WebAll the elements of the periodic table are arranged in order of increasing atomic (proton) number. The table was named the periodic table because similar properties occur at regular intervals. Elements with similar properties are in columns called groups. Elements to the left of this line are metals. Elements in the same group of the periodic ... WebFor ionic compounds you have to balance the charge of each part by multiplying each ion until the sum of the charges = 0; Example: what is the formula of aluminium sulfate? Write out the formulae of each ion, including their charges; Al 3+ SO 4 2-Balance the charges by multiplying them out: Al 3+ x 2 = +6 and SO 4 2- x 3 = -6; so +6 – 6 = 0
