Question

calculate the number of protons, neurons and electrons in 80Br 35...ans of que 39

Answer 1

protons=80-35=25electrons =35. and neutrons=35. hope ur help

Answer 2

Given
mass of element = 80
atomic number = 35

As number of electrons = Atomic number = number of protons

then
Electrons = 35
Protons = 35

Also
Total number of Protons + Neutrons = Mass no
then
35 + no. of neutron = 80
or
no. of neutrons = 45

Hope it helps
