Element X has three electrons in its outermost orbit.
Element Y has seven electrons in its outermost orbit.
What is the chemical formula of the ionic compound formed by these elements when they react together? (Use X and Y as the chemical symbols.)
Answers: 2
.
cation and element Y is having an oxidation state of -1 as it can gain one electron in its outermost orbit called as 
anion. Thus they combine and their oxidation states are exchanged and written in simplest whole number ratios to give neutral
