Question 1

Different types of radiation on their charges

Answer 1

Alpha Radiation (α): Consists of alpha particles (2 protons and 2 neutrons). It has a +2 charge and is relatively heavy.

Beta-minus (β-): An electron with a -1 charge.

Beta-plus (β+): with a +1 charge.

Gamma Radiation (γ): Consists of high-energy photons with no charge and no mass.

Neutron Radiation: Comprises neutrons, which are uncharged particles.

Question 2

Compare Nuclear and Chemical Reactions

Answer 2

Nuclear Reactions:

Involve changes in the nucleus of an atom.
Can result in the transmutation of elements (changing one element into another).
Typically involve large amounts of energy.
Can emit alpha, beta, or gamma radiation.

Chemical Reactions:

Involve the rearrangement of electrons in chemical bonds.
Do not change the identity of the elements involved.
Generally involve less energy compared to nuclear reactions.
No radiation is typically emitted (unless involving radioactive substances).
