Question

for the symbol H, Dec and T tabulate three sub atomic particles found in each of them .....​

Answer 1

a) H ( Protium ) (11H)

Atomic number = 1

Mass number = 1

Number of protons = 1

Number of electrons = 1

Number of neutrons = Nil

(b) D ( Deuterium ) ( 21H )

Atomic number = 1

Mass number = 2

Number of protons = 1

Number of electrons = 1

Number of neutrons = 1

(c) T ( Tritium ) ( 31H )

Atomic number = 1

Mass number = 3

Number of protons = 1

Number of electrons = 1

Number of neutrons = 2

hope it helps !!
