How are atoms glued together to make molecules?

The bonds that hold atoms together to form molecules are called covalent bonds. They are pretty tough and not easily made or broken apart. It takes energy to make the bonds and energy is released when the bonds are broken.

How atoms are held together to form a substance?

Chemical bonds are forces that hold atoms together to make compounds or molecules. Atoms with relatively similar electronegativities share electrons between them and are connected by covalent bonds. Atoms with large differences in electronegativity transfer electrons to form ions.

What are two main ways that atoms can stick together?

There are three basic ways that the outer electrons of atoms can form bonds:

• Electrons can be transferred from one atom to another.
• Electrons can be shared between neighbouring atoms.
• Electrons can be shared with all atoms in a material.

When a molecule forms which part of the atoms cause them to stick together?

A covalent bond is formed when two atoms share electron pairs. In a covalent bond, the stability of the bond comes from the shared electrostatic attraction between the two positively charged atomic nuclei and the shared, negatively charged electrons between them.

How do atoms make molecules?

When two or more atoms link up, they create a molecule . A molecule of water is made of two atoms of hydrogen (H) and one atom of oxygen (O). The molecular mass is the sum of the masses of all the atoms in the molecule. A collection of molecules is called a compound.

How is the molecule of a substance formed?

A molecule is formed when two or more atoms of an element chemically join together. If the types of atoms are different from each other, a compound is formed. Water is also a molecule because it is made from atoms that have been chemically combined.

What happens when atoms combine to form a compound explain with an example?

When atoms combine to form a new substance, they are forming chemical bonds that bind them together. For instance both diamond and graphite are made of carbon atoms. However, due to different types of bonds, they form entirely different types of structures.

Why is it important that atoms stick together in some way what can they form?

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.

When an atom loses an electron what does it become?

If an atom has an equal number of protons and electrons, its net charge is 0. If it gains an extra electron, it becomes negatively charged and is known as an anion. If it loses an electron, it becomes positively charged and is known as a cation.

When one atom loses an electron and another atom accepts the electron?

This electron exchange results in an electrostatic attraction between the two atoms called an ionic bond. An atom that loses one or more valence electrons to become a positively charged ion is known as a cation, while an atom that gains electrons and becomes negatively charged is known as an anion.

What are atoms and molecules give examples?

Difference Between an Atom and Molecule

	Atom	Molecule
Examples	Oxygen (O)	Water (H2O)
	Hydrogen (H)	Sodium chloride (NaCl)
	Argon (Ar)	Nitrogen (N2)
	Plutonium (Pu)	Carbon dioxide (CO2)
