How can ionic compounds conduct electricity?

Back

Ionic compounds can conduct electricity when dissolved in water, as the ions are free to move.

Front

Which ion is written first in the chemical formula for an ionic compound?

Back

The positive ion (cation) is written first.

Front

What is a cation?

Back

A cation is a positively charged ion that is formed when an atom loses one or more electrons.

Front

What is an anion?

Back

An anion is a negatively charged ion that is formed when an atom gains one or more electrons.

What is the significance of subscripts in a chemical formula?

Back

Subscripts indicate the number of atoms of each element in a compound.

Front

What is the octet rule?

Back

The octet rule states that atoms tend to gain, lose, or share electrons to achieve a full outer shell of eight electrons.
