प्रश्न
Draw a diagram of a simple atom showing the nucleus and electrons. In this atom:
(a) What type of charge will there be on the nucleus?
(b) What is the value of this charge?
उत्तर
The central sphere is nucleus where small spheres are electron moving in circular orbit around nucleus.
(a) There is positive charge on nucleus.
(b) Charge on proton is equal to +1.6 x 10-19 c and neutron is neutral so value of charge on nucleus is p x 1. 6 x 10-19 c where p is the number of proton in nucleus.
