Concept explainers
(a)
Interpretation:
The nuclear symbol for a beta particle is to be stated.
Concept introduction:
When a narrow beam is aimed into an electric field, it divides into three beams. These three beams indicate that radioactive emissions are made up of three different products. These three products are alpha particles, beta particles, and gamma particles. Alpha, beta, and gamma are the radioactive particles.
(b)
Interpretation:
The name for the Greek letter

(c)
Interpretation:
The most penetrating and the least penetrating among the radiations alpha, beta, and gamma are to be stated.
