Answer : The correct option is, (A) Aluminum foil

Explanation :

Penetration power : It is the movement of particles or the ray through an object.  As we know that the more the energy of a particle, the more will be the penetrating power.

The ascending order of the penetration power of alpha rays, beta rays, and gamma rays are:

Alpha rays < Beta rays < Gamma rays

The penetrating power of the alpha, beta and gamma rays varies greatly.  That means,

  • The alpha particles are restricted by paper.
  • The beta particles can pass through the paper but it can not pass through the aluminum foil.
  • The restriction of gamma rays is very difficult. It can be restrict or blocked only by concrete, lead, or other heavy shielding.

Hence, Aluminium foil will stop beta particles.

mafiozo [28]

Answer:

Option B is correct.

4

Explanation:

We know that an atom consist of electron, protons and neutrons. Protons and neutrons are present with in nucleus while the electrons are present out side the nucleus.

All these three subatomic particles construct an atom. A neutral atom have equal number of proton and electron. In other words we can say that negative and positive charges are equal in magnitude and cancel the each other. For example, if neutral atom has 6 protons than it must have 6 electrons. The sum of neutrons and protons is the mass number of an atom while the number of protons are number of electrons is the atomic number of an atom.

In given problem we are given with 2 neutrons of helium. We know that the atomic number of He is 2. Thus Mass number of He is,

Number of neutrons + number of proton

2 + 2 = 4

Thus, option B is correct.
