how do atoms come together to form molecules

by Foster Simonis Published 11 months ago Updated 3 weeks ago

When atoms join together to form molecules, they are held together by chemical bonds. These bonds form as a result of the sharing or exchange of electrons between the atoms. It is only the electrons in the outermost shell that ever get involved in bonding.

What are two ways atoms can combine to form compound?

There are three possible ways for any atom to take in pursuit of an octet:

  1. Electrons could be given up to some other atoms or group of atoms.
  2. Electrons could be gained from some other atoms.
  3. Electrons could be shared between two atoms.

Does atom combine with other atoms or molecules?

Atoms combine to form molecules, which then interact to form solids, gases, or liquids. For example, water is composed of hydrogen and oxygen atoms that have combined to form water molecules.

Is it true that atoms combine to form compounds?

When two or more elements combine to form a new substance, it is called a compound. There are many different types of compounds, because atoms of elements combine in many different ways to form different compounds. Examples include water (H2O) and table salt (NaCl). The smallest part of a compound is a molecule.


How do atoms combine to form molecules?

When atoms combine by forming covalent bonds, the resulting collection of atoms is called a molecule. We can therefore say that a molecule is the simplest unit of a covalent compound.

Shell. Remember one thing atoms always keep trying to fill their shells.

Why do atoms bond to make molecules?

Atoms form chemical bonds to make their outer electron shells more stable. The type of chemical bond maximizes the stability of the atoms that form it.

Do all atoms combine to form molecules?

At the most basic level, all organisms are made of a combination of elements. They contain atoms that combine together to form molecules. In multicellular organisms, such as animals, molecules can interact to form cells that combine to form tissues, which make up organs.

Why do atoms form molecules quizlet?

How do atoms form molecules? atoms form molecules by sharing electrons through chemical bonds. This results in atoms becoming more stable.

What holds a molecule together?

Explanation: The chemical bonds that hold the atoms of a molecule together are covalent bonds, formed when two atoms share electrons.

How molecules are formed from non metals?

Covalent bonds form when two or more nonmetals combine. For example, both hydrogen and oxygen are nonmetals, and when they combine to make water, they do so by forming covalent bonds.

How do you explain molecules to kindergarteners?

A molecule is two or more atoms joined (or “bonded”) tightly together. The number and kinds of atoms in a molecule, and the way they are arranged, determine what substance it makes. For example, a molecule made of two oxygen atoms joined to one carbon atom forms carbon dioxide, a colorless gas.

How are molecules formed Class 9?

Atoms of different elements join together in definite proportions to form molecules of compounds. For example, a molecule of water consists of two atoms of hydrogen and one atom of oxygen to form a triatomic molecule H2O.

What are the parts of a molecule?

Molecules are made up of groups of atoms. Describing the structure of an atom, an atom is also sub-divided into smaller units. Proton, electrons, and neutrons are sub-particles of an atom. The protons and neutrons are contained inside the nucleus of the atom and electrons revolve around the nucleus.

Which part of an atom contains protons and neutrons?

The nucleus of an atom contains protons and neutrons only, and therefore is positively charged. The electrons occupy the region of space around the nucleus. Therefore, most of the mass is concentrated within the nucleus. The center of the atom is called the nucleus.

How to determine the atomic weight of an element?

The atomic weight of an element is determined by combining the total number of protons and neutrons in the nucleus. An electron carries a single negative charge. If an atom of an element is to have zero charge, it must have the same number of electrons as protons.

What is a collection of two or more atoms that make up the smallest recognisable unit into

A molecule is a collection of two or more atoms that make up the smallest recognisable unit into which a pure material may be split while maintaining its makeup and chemical characteristics. Some examples of molecules are

Why is it impossible to measure the size of an isolated atom?

It is impossible to measure the size of an isolated atom because it’s difficult to locate the positions of electrons surrounding the nucleus. However, the size of an atom can be estimated by assuming that the distance between adjacent atoms is equal to half the radius of an atom.

Why is the nucleus positively charged?

So we can say that the nucleus is positively charged due to the presence of protons. The nucleus is a bulk mass at the centre of an atom. Atoms are largely vacant. Every element has a certain atomic number. The atomic number of an element is defined as the number of protons present in its nucleus. It is denoted by Z.

What are the basic building blocks of matter?

Atoms are defined as “the basic building blocks of matter”. It is the smallest constituent unit of matter that posses the properties of the chemical element. Atoms don’t exist independently, instead, they form ions and molecules which further combine in large numbers to form matter that we see, feel and touch.

How are atoms linked together?

Atoms, in a sense, are tied together to form molecules. The atoms of molecules are linked together through a reaction known as chemical bonding. A chemical bond is a force that holds atom together.

How are compounds formed?

Some compounds are formed when electrons are shared between two atoms to fill up the incomplete outer shell of both in order to attain the stable configuration of an inert gas. This usually occurs when reaction takes place between atoms of Group IV, V, and VII. The chemical bond in which two atoms share a pair of electron and form molecules is called covalent bond. The atoms of covalent compounds are not free like those in ionic compounds. They are tightly linked to one another by the covalent bond. Hence each independent particle is a combination of the atoms.

What is the chemical bond in which two atoms share a pair of electrons and form molecules called?

Illustrations of covalent bonds. pinterest-pin-it. The chemical bond in which two atoms share a pair of electron and form molecules is called covalent bond . pinterest-pin-it. Covalent bonds are classified into non polar and polar covalent bonds.

What is the difference between ionic and covalent bonds?

It is a force that holds atom. Ionic bond is transferring of atom while Covalent bond is sharing a pair of electron. Polar bond is unequal sharing of electrons and Non-polar bond is equal sharing of electrons.

What type of bond is the transfer of electrons between atoms?

There are two types of chemical bonds, (1) ionic bond and (2) covalent bond.

How are chemical bonds formed?

Chemical bonds are produced when the outer-shell electrons are either transferred or shared from one atom to another. The formation of chemical bonds usually enables an atom to acquire a chemically stable outer-shell consisting of an octet of electrons. There are two types of chemical bonds. (1) Ionic bond, in which electrons are actually transferred from the outer-shell of one atom to the second atom. The resulting particles are ion – atom or groups of atoms with an unbalance electrostatic charge. (2) Covalent bond, in which two atoms share a pair of electrons and form molecules. The bond that results whenever unequal sharing occurs is called a polar covalent bond. Equal sharing of electrons is called non polar covalent bond.

Why is chemical bonding important?

It is either ionic bond (transferring of electrons) or covalent bond (sharing of electrons). Chemical bonding is important because with the help of this , we will know how to combine substances to form new compounds.


Atoms are the building blocks of all matter. Everything is made of atoms - even yourself.


Molecules are made when two or more atoms chemically bond together. Atoms from different elements can combine. When the atoms are from different elements, the molecule can also be called a compound.

Drawing atoms and molecules

Atoms can be drawn as circles. But all the atoms of an element need to look exactly the same.
