Question

If an ion with unit negative charge has a mass no
37 and contains 11 1% more nutrons than that of the no of electrons
, then write the symbol of the atom

Pankaj Singh · Accepted Answer

Let the number of electrons in the ion carrying a negative charge be x.

Then,

Number of neutrons present

= x + 11.1% of x

= x + 0.111 x

= 1.111 x

Number of electrons in the neutral atom = (x – 1)

(When an ion carries a negative charge, it carries an extra electron)

∴ Number of protons in the neutral atom = x – 1

Given,

Mass number of the ion = 37

∴ (x – 1) + 1.111x = 37

2.111x = 38

x = 18

∴The symbol of the ion is

0

If an ion with unit negative charge.. has a mass no. 37 and contains 11.1% more nutrons than that of the no. of electrons , then write the symbol of the atom.
