Question

3.
If no. of protons in X-2 is 16. then no. of electrons in X+2 will be-
(1) 14
(2) 16
(3) 18​

Answer 1

Answer:

1) 14

Explanation:

so no.of protons x is 16

no.of electrons x+2 = 14

Answer 2

Answer:

if x - 2 = 16

then x = 16 + 2

therefore x = 18

now number of electrons in x + 2 will be

x + 2 = O

x - 2 = 16
