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
