Question

calculate proton neutron and electron in a species are equal to the 18 15,16​

Answer 1

Answer:

(1) Atomic No. - 18

(2) Atomic No. - 15

(3) Atomic No. - 16

Explanation:

Since,Atomic No.=No. of protons=No. of electrons

Therefore,

(1) protons =18

electrons = 18

(2) protons = 15

electrons =15

(3) protons = 16

electrons = 16

Mass No. of (1) = 40

Mass No. of (2) = 31

Mass No. of (3) = 32

Since, No. of neutron = Mass No. - No. of protons

Therefore,

No. of neutrons of (1) = 40-18 = 22

No. of neutrons of (2) =31-15 = 16

No. of neutrons of (3) = 32-16 = 16
