Question

A neutron breaks down to form ?

Answer 1

1. A.) A proton and electron.

2. C.) Proton.

3. C.) Mass remains the same.

4. D.) Decreased by 2.

Answer 2

Answer:

1) The correct answer is option A.

2) The correct answer is option B.

3) The correct answer is option C.

4) The correct answer is option C.

Explanation:

Alpha Decay, a heavier nuclei decays into lighter nuclei by releasing alpha particle. The mass number is reduced by 4 units.

$_A^Z\textrm{X}\rightarrow _{A-2}^{Z-4}+_2^4\alpha$

In Beta-decay, a neutron breaks down into proton and an electron releasing a beta-particle. The beta particle released carries a charge of -1 units.

$_Z^A\textrm{X}\rightarrow _{Z+1}^A\textrm{Y}+_{-1}^0\beta$

In Gamma ray emission, an unstable nuclei gives out large amount of energy by a spontaneous electromagnetic process and releases $\gamma$ -radiations. These radiations are electrically neutral.

$_Z^A\textrm{X}^*\rightarrow _Z^A\textrm{X}+_0^0\gamma$
