Ion formation, ionic and metallic bonding

Front

What happens to metals when they become ions?

Back

Metals lose electrons when they become ions.

Front

Front

What is the formula of Sodium oxide?

Back

The formula of Sodium oxide is Na2O.

Front

What is the basis of a metallic bond?

Back

The basis of a metallic bond is the attraction between positive metal ions and free floating electrons.

Front

Define ionic bond.

Back

An ionic bond is a chemical bond formed between two ions with opposite charges.

Front

What is the octet rule?

Back

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

Front

What type of elements typically form ionic bonds?

Back

Ionic bonds typically form between metals and nonmetals.

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.
