Question

What is natural radioactivity? What type of radiations are emitted ? Write two properties of each one.

Answer 1

$\bold{ANSWER}$

✨The spontaneous process by virtue of which a nucleus changes its state with the emission of An some particle/s or e.m.w. is called $\bold{Natural\: radioactivity}$ .

For example :-
=============
Radium and uranium are natural radioactive elements.
Following three types of radiations are emitted Aipha (a), Beta (B) and gamma .

@$\bold{properties\: of\: α-particles }$

(i) These particles carry positive (+ ve) charge.

(ii) These are deflected by electric and magnetic fields.

@$\bold{properties\: of\: β-particles}$

I) These particles carry negative (-ve) charge.
(ii) These are deflected by electric and magnetic fields.

@$\bold{properties\: of\: y-rays}$

i)These are the packets of energy and carry no charge.

ii) These are not deflected by electric and magnetic fields.

Answer 2

Explanation:

\bold{ANSWER}ANSWER

✨The spontaneous process by virtue of which a nucleus changes its state with the emission of An some particle/s or e.m.w. is called \bold{Natural\: radioactivity}Naturalradioactivity .

For example :-

=============

Radium and uranium are natural radioactive elements.

Following three types of radiations are emitted Aipha (a), Beta (B) and gamma .

@\bold{properties\: of\: α-particles }propertiesofα−particles

(i) These particles carry positive (+ ve) charge.

(ii) These are deflected by electric and magnetic fields.

@\bold{properties\: of\: β-particles}propertiesofβ−particles

I) These particles carry negative (-ve) charge.

(ii) These are deflected by electric and magnetic fields.
