Question

An ion with mass number 37 possesses one unit of negative charge. If the ion contains more neutrons than electrons, find the symbol of the ion.​

Answer 1

Answer:

Hope it helps you.

Explanation:

Let x be the number of electrons.

The number of neutrons is x+0.111x=1.111x.

The number of protons is x−1.

The mass number is 37.

It is equal to the sum of the number of protons and the number of neutrons.

x−1+1.111x=37

2.111x=38

x=18

The number of electrons is 18.

The number of protons is 17.

Hence, the symbol of the ion is

17

37
