no. of electrons = no. of proton
protons = 7
electrons = 7
mass number = no. of neutrons + no. of proton
18 = neutron + 7
no. of neutrons = 18-7
neutron = 11
atomic no. = no. of proton
Atomic no. = 7
protons = 7
electrons = 7
mass number = no. of neutrons + no. of proton
18 = neutron + 7
no. of neutrons = 18-7
neutron = 11
atomic no. = no. of proton
Atomic no. = 7
