Hydrogne has three isotopes which are wirtenas:
`overset(1)underset(1)H,overset(2)underset(1)H,overset(3)underset(1)H`
Explain why:
(a) These isotopes have identical chemical properties. ,(b) These isotopes are electrically neutral
(c ) The isotopes differ fin theeir masses because they differ in their of certain elements are given:

Explanation

(a) The isotopes have idential chemical propertites because all of them have one electron in the only shell (K-shell)
(b) The isotopes are electrically neurtral because each one has one proton and one elctron
(c ) The isotopes different in their masses because they different in their mass number (1,2and 3 respectively)
