Answer»

isotopes and isobars
isobars and isotones
isotones and isotopes
isobars and isotopes.

Solution :`{:(""(32)^(76)Gerarr{:("protons = 32 = ELECTRONS"),("neutrons = 76 - 32 = 44"):}),(""(34)^(76)Serarr{:("protons = 34 = electrons"),("neutrons = 76 - 34 = 42"):}):}]{:("Mass no. same"),("but atomic no."),("different. So,"),("they are isobars."):}`
`{:(""(14)^(30)Sirarr{:("protons = 14 = electrons"),("neutrons = 30 - 14 = 42"):}),(""(16)^(32)Srarr{:("protons = 16 = electrons"),("neutrons = 32 - 16 = 16"):}):}]{:("Same no of"),("neutrons."),("So, they are"),("isotones."):}`
