Chemical bonding

Front

What happens when an atom gains an electron?

Back

The atom becomes negatively charged.

Front

What happens when an atom loses an electron?

Back

The atom becomes positively charged.

Front

Are atoms more stable when they are bonded together or when they are apart?

Back

Atoms are more stable when they are bonded together.

Front

What charges attract each other?

Back

Opposite charges attract each other.

Front

What happens when a sodium atom loses an electron?

Back

The sodium atom becomes positively charged.

Front

What is a chemical bond?

Back

A chemical bond is a lasting attraction between atoms that enables the formation of chemical compounds.

Front

What are the two main types of chemical bonds?

Back

Ionic bonds and covalent bonds.

Front

What is an ionic bond?

Back

An ionic bond is formed when one atom transfers electrons to another atom, resulting in oppositely charged ions that attract each other.

Front

What is a covalent bond?

Back

A covalent bond is formed when two atoms share one or more pairs of electrons.

Front

What is the octet rule?

Back

The octet rule states that atoms tend to bond in such a way that they have eight electrons in their valence shell, achieving stability.
