Question

The number of electrons in an ion M² will
be CAtomic number = 20)​

Answer 1

e = (2 + 8 + 14) = 24

Here, mass number : A = 58

Z = No. of protons = No. of electrons in the neutral atom = 24 +2 = 26

Mass Number = 58

No. Of Neutrons = Mass No. - Atomic No. = 58 - 26 = 32

thank you

Answer 2

《Answer 》

e=(2+8+14)

=24

here mass no is 58

Z=24+2

=26

Mass no=58

No of neutrons =58-26

=32
