An element X has a valency of 2. Write the simplest formula for:(a) bromide of the element(b) oxide of the element
(a)Valency of X = 2
Valency of Br = 1
Formula for bromide of element X can be worked out by crossing the valency of the constituent elements.
Therefore, formula for bromide of X is: XBr2.
(b)Valency of X = 2
Valency of Oxygen = 2
Formula for oxide of element X can be worked out by crossing the valency of the constituent elements.
Therefore, formula for oxide of X is XO.
