Solution

The correct option is D Remains unchanged
Gamma radiation is produced from the release of pure energy from a nucleus. A gamma ray has no mass and no charge, it is simply a stream of high frequency energy.So atomic number remains unchanged .

Q. What happens to the atomic number of an element when

γ

-radiation, is emitted?

Q. Assertion :

{_{z} X}^{A}

undergoes

2

α

- decays,

2

β

- decays (negative

β

) and

2

γ

-decays. As a result , the daughter product is

{_{z - 2} Y}^{A - 8}

Reason: In

α

- decay, the mass number decreases by

4

unit and atomic number decreases by

2

unit. In

β

- decay (negative

β

), the mass number remains unchanged and atomic number increaess by

1

unit. In

γ

-decay, mass number and atomic number remain unchanged

Q. Assertion :

_{Z} X^{4}

undergoes

2 α - d e c a y s, 2 β - d e c a y s

(negative

β

), and

2 γ - d e c a y s

. As a result, the daughter product is

_{z - 2} Y^{A - B}

Reason: In

α - d e c a y

, the mass number decreases by 4 unit and atomic number decreases by 2 unit. In

β - d e c a y

(negative

β

), the mass number remains unchanged and atomic number increases by 1 unit. In

γ - d e c a y

, mass number and atomic number remain unchanged.

Q. STATEMENT - 1 :

_{Z} X^{A}

undergoes 2

α

decays, 2

β

decays (negative

β

) and 2 decays. As a result the daughter product is

_{Z - 2} Y^{A - 8} .

STATEMENT -2 : In

α

decay the mass number decreases by 4 unit and atomic number decreases by 2 unit. In

β

decay (negative

β

) the mass number remains unchanged and atomic number increases by 1 unit. In

γ

decay, mass number and atomic number remains unchanged.

Q. A nuclide has mass number

(A)

and atomic number

(Z)

. During a radioactive process if
1. both

A

and

Z

decrease, the process is called

α

-decay.
2.

A

remains unchanged and

Z

decreases by one, the process is called

β^{+}

or positron decay or

K

-electron capture.
3. both

A

and

Z

remain unchanged, the process is called

γ

-decay.
4. both

A

and

Z

increase, the process is called nuclear isomerism.
