Question

Write down the number of electrons in X & neutrons in Y & the formula of the compound formed by X & Y.
1. Element X is a metal with a valency
2. Element Y is a non-metal with a valency

Answer 1

Explanation:

X --> X^(+2) + 2 electron

Y + 3electron --> Y ^(-3)

pls mark it as brainliest

Answer 2

Answer:

Element X is a metal with valency 2 that means it is a reducing agent and can release 2 electrons but cannot accept while Y is a non-metal with a valency 3 that means it can accept 3 electrons and the stable ion is Y

3−

.

So the balance equation for formation of ion is :

X−2e

−

→X

2+

Option (B) is showing addition of two electrons that will not be able to form stable ion Y

3−

. Metal ion X

+

is also unstable.
