B) write chemical formula of its chloride
Answers
Answer:
Symbol X P
Valency 3 3-
So , by criss cross method ,Chemical formula = XP
---------------------------------------------------------------------------------------------------------------------------------------------------
Symbol X CO₃
Valency 3 2
So , by criss cross method , chemical formula = X₂ (CO₃)₃

X is a metal.
The elements with valency less than 5 are known as metals.
The elements with valency more than or equal to 5 are known as non -metals.
The elements with valency zero are noble gases / inert gases....
