Chemical Bonding and Properties (Warm-Up)

Front

What is an Ionic Bond?

Back

A bond formed between a metal and a nonmetal, where electrons are transferred from one atom to another.

Front

What happens to an atom when it loses an electron?

Back

It becomes a cation, which is a positively charged ion.

Front

What is a Covalent Bond?

Back

A bond formed between two nonmetals, where electrons are shared between the atoms.

Front

What type of bond is formed in KBr?

Back

Ionic bond, formed between potassium (K) and bromine (Br).

Front

What do atoms with many valence electrons (5-7) tend to do?

Back

They tend to gain more electrons to achieve a full outer shell.

Front

What is a cation?

Back

A positively charged ion that results from an atom losing one or more electrons.

Front

What is an anion?

Back

A negatively charged ion that results from an atom gaining one or more electrons.

Front

What is the octet rule?

Back

Atoms tend to gain, lose, or share electrons to achieve a full outer shell of eight 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 metallic bond?

Back

A bond formed between metal atoms, characterized by a 'sea of electrons' that are free to move.
