"Electronegativity is the power of an atom to attract the electron density in a covalent bond to itself"
In order to understand electronegativity we mu...

Remember that ionisation energy is an endothermic process, in which energy from the chemical system is used to remove electrons from atoms in the GASEOUS STATE.

A coordinate bond is a bond formed through the donation of a lone pair of electrons from an atom bonding to another atom which has an empty orbital.The lone pair from one atom is donated to the empty orbi...

Step 1: Using the periodic table, find how many electrons are in the outer shell of the central atom. Step 2: Add one electron for every other atom that the central atom is bound to. Step 3: Look at the n...

An empirical formula is the simplest whole number ratio of atoms of each element present in the compound.1) Divide by atomic relative mass to find the number of moles. 2) Find a ratio between the moles. 3...
