Question

Mass number of an atom is 27 and number of neutrons is 14 what is the electrons in tha ion

Answer 1

Answer:

13

Explanation:

mass no. = no. of neutrons + no. of protons

so, 27 = n +p

27= 14+p

p= 13

and to maintain electric neutrality the no. of protons is equal to no. of electrones so, the no. of electrones is 13.

Answer 2

Answer:

13

Explanation:

A=P+N

P=27-14=13

P=E

THEREFORE , E=13
