Ionic, Covalent & Metallic

Front

What happens to potassium (K) when it bonds with chlorine (Cl) to form KCl?

Back

Potassium (K) loses an electron to have a full valence shell, becoming positively charged.

Front

What type of bond involves electron donation or transfer?

Back

Ionic bond.

Front

True or False: Ionic compounds are formed by the attraction of positive to negative charges.

Back

True.

Front

What is meant by 'sea of electrons' in metallic bonding?

Back

It refers to delocalized electrons that are free to move throughout the metal structure.

Front

Why do atoms bond?

Back

Atoms bond in order to have a full valence shell.

Front

What is an ionic bond?

Back

A bond formed through the transfer of electrons from one atom to another, resulting in the attraction between positively and negatively charged ions.

Front

What is a covalent bond?

Back

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

Front

What is a metallic bond?

Back

A bond formed between metal atoms where electrons are shared in a 'sea' of delocalized electrons.

Front

What is the charge of an ion formed when an atom loses an electron?

Back

The ion becomes positively charged.

Front

What is the charge of an ion formed when an atom gains an electron?

Back

The ion becomes negatively charged.
