How many electron potons and mass number in a nucleus of atomic number `11` and mass `24`?
(i) number of electron = (ii)number of proton = (iii)number of neutrons =

Text Solution

Verified by Experts

Number of protons in nucleus =atomic number` 11`
Number of elcectrons in an atom =Number of protns `=11`
Number of neutrons = mass number (A) - atomic number `(Z) =24 -11 =13.
