Question

Hey frnd !!

need ur help!

A ion with mass no. 37 posses one unit of negative charge if the ion contain 11.1% more neutral than electron .find symbols of the ion ???

spam ans will be deleted on the spot .........☺☺☺

Answer 1

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

Therefore 37 = 1.111x + x -1

Or 2.111 x = 38

Or x = 18

Therefore no of protons = atomic no = x -1 = 18 – 1 = 17
37
the symbol is cl-
17

✌✌ hope you like my answer and it may help you ❤❤☺
