Front

What do covalent compounds do?

Back

Covalent compounds share electrons.

Front

How do covalent bonds form?

Back

Electrons are shared to fill outer electron shells.

Front

What does the group number in the periodic table represent?

Back

The number of valence electrons.

Back

2 electrons.

Front

What is a covalent bond?

Back

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

Front

What is the difference between ionic and covalent bonds?

Back

Ionic bonds involve the transfer of electrons, while covalent bonds involve the sharing of electrons.

Front

What is a molecule?

Back

A molecule is a group of atoms bonded together, representing the smallest fundamental unit of a chemical compound.

Front

What is a polar covalent bond?

Back

A polar covalent bond is a type of bond where electrons are shared unequally between atoms, resulting in a molecule with a slight charge.

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.
