Ionic Bonding

Metals

They normally lose electrons during chemical reactions. Usually, form positive ions.

Non-metals

They normally gain electrons during chemical reactions. Usually form negative ions.

Ion

An atom that has a positive or negative charge.

what is a Anion

An ion with a negative charge. Formed by gaining electrons

what is a Cation

An ion with a positive charge. formed by losing electrons.

what is an Ionic compound

A giant ionic lattice is a compound that has ionic bonds.

how do atom becoming an ion

When a neutral atom loses an electron, it loses a negative charge. It becomes a positive ion. When a neutral atom gains an electron, it gains a negative charge and becomes a negative ion

explain Ionic bonds

is is an attraction between two oppositely charged ions.

A compound that is ionically bonded

NaCl ect

NaCl

sodium chloride (salt)

Mg2+

magnesium ion (cation)

protons and neutrons

found in the nucleus of an atom

electrons

Negatively charged particles

what are two types of atoms required for ionic bonding

non metal and metal

reason for high melting point

giant ionic lattice

strong electrostatic force of attraction between oppositely charged ions

therfore high levels of energy reqired to overcomes forces
