Question

Draw the structure of the following atoms showing the nucleus containing – protons, neutrons and the orbits with the respective electron:

Isotopes of hydrogen [1₁H, 2₁H, 3₁H]

Answer 1

Structure of atoms:

\[\ce{^2_1H}\] 

\[\ce{^3_1H}\]

Z is Atomic Number and A is the mass number
Isotopes of hydrogen \[\ce{^1_1H}\]
Z = 1 = p = e
∴ e = 1
A = p + n
1 = 1 + n
∴ n = 1 − 1 = 0
