A group of atom bonded together.
Any of the elements in group ( 1 ) in the periodic table.
ALKALI EARTH METALS
Any of the elements in group ( 2 ) in the periodic table.
Elements in group 7 which are non-metal.
Gases in group (8) which are in unreactive.
Any of the set of metallic elements occupying a central block.
A table of the chemical elements arranged in order of atomic number, usually in rows which has the same properties.

Is a force between particles.
The forces between particles that are caused by their electric charges.
Is the charge of the ions.For example copper has a valency of 2+.
Giant ionic lattice
Positive and negative ions held in place by strong electrostatic attraction between oppositely charged ions.
It's bond between metal and non-metal.
An electrically charged atom or group of atoms formed by the loss or gain of one or more electrons,
Two metals which share electrons.
Simple molecular substances
Low melting and boiling point and non-conductive .
Molten means melted into a liquid state
Giant covalent structure
Giant covalent structures contain a lot of non-metal atoms, each joined to adjacent atoms by covalent bonds. The atoms are usually arranged into giant regular lattices - extremely strong structures because of the many bonds involved.

A precious stone consisting of a clear and typically colorless crystalline form of pure carbon, the hardest naturally occurring substance.
A form of carbon having molecules of 60 atoms arranged in a polyhedron resembling a geodesic sphere.
