Answer:
b) beta decay
Explanation:
Beta radiations:
Beta radiations are result from the beta decay in which electron is ejected. The neutron inside of the nucleus converted into the proton an thus emit the electron which is called β particle.
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.
(2) three fewer valence electrons is your answer.
1. Chemical name
2. Generic name
3. Brand name
In the blank there will be WAVELENGTH.
In a longitudinal wave, the WAVELENGTH is the distance from one compression to the next compression or from one rarefaction to the next rarefaction.
