Question

Write a nuclear balanced equation An atom of strontium-80 emits a positron

Answer 1

Answer:

₃₈Sr⁸⁰  →  ₃₇Rb⁸⁰ + ⁰₊₁e

Explanation:

Positron emission:

It is also called beta positive decay in which the neutron inside of the nucleus converted into the proton an thus emit the positron and electron neutrino which is called β particle.

Properties of beta radiation:

The mass of beta particle is smaller than the alpha particles.

They can travel in air in few meter distance.

These radiations can penetrate into the human skin.

The sheet of aluminium is used to block the beta radiation

⁴₆C → ¹⁴₇N + ⁰₋₁e

The beta radiations are emitted in this reaction. The one electron is ejected and neutron is converted into proton.  It is beta minus decay.
