Question

(a) α-rays, β-rays and cathode rays consist of particles of matter.

(b) The addition of a neutron to the nucleus of an atom do not affects its chemical properties.

(c) When the speed of electron increases its specific charge decreases.

(d) The fundamental particle with highest specific charge is proton​

Answer 1

Answer:-

_____________________________________

Q. Give reasons:-

• Alpha particles carry a positive charge, beta particles carry a negative charge, and gamma rays are neutral. An alpha particle is made up of two protons and two neutrons bound together. Beta particles are high energy electrons. Gamma rays are waves of electromagnetic energy, or photons.

• The number of neutrons in a nucleus affects the mass of the atom but not its chemical properties. Thus, a nucleus with six protons and six neutrons will have the same chemical properties as a nucleus with six protons and eight neutrons, although the two masses will be different.

• When speed of electron increases the specific charger decreases because with increase in velocity charge remains constant. Another reason is specific charge is the ratio of the charge to mass.

• Yeah ! It's proton
