Ans. The central longitude that divides the earth into the eastern hemispher
Answer:
We have
\begin{gathered}\sf Atomic \; Number \begin{cases} \bf X = 16 \\ \bf Y = 12\end{cases}\end{gathered}
AtomicNumber{
X=16
Y=12
So,
They may be broken into Electronic configuration to find the modem
Element X = 2,8,6
Element Y = 2,8,2
Now
We may observe that the both element are divided or have three shells. They belong to third period
Now
According to the question
The element x will have electropositive ion and element Y will have the electronegative ion.
Chemical equation is
\sf Mg + S \longrightarrow MgSMg+S⟶MgS
