I hope my answer has come to your help. God bless and have a nice day ahead!
To calculate the atomic mass of a single atom of an element, add up the mass of protons and neutrons. Example: Find the atomic mass of an isotope of carbon that has 7 neutrons. You can see from the periodic table that carbon has an atomic number of 6, which is its number of protons.
Hope this helps :)
X has valency 3 and oxide ion has valency 2
So, the formula of oxide will be X
2
O
3
