Can any one help me​

Answer 1

Answer:

27

Explanation:

the atom is neutral that means the

no of proton= no of electron

and the no of electron = 13

so no of proton = 13

mass number = no of proton + no of neutron

= 13+14

= 27

hope u got it

Answer 2

Answer:

here is your solution

Explanation:

it is given that it is an neutral atom so the number of electron is equal to proton as the atom has not reacted and formed ion

so the proton is also 13

mass number = proton + neutron

so mass number = 13 + 14 which is 27u.

so the mass number is 27u. option d
