A : During radioactive disintegration an alpha -particle and a beta -particle do not emit simultaneously from any nucleus. R : An alpha -particle emits from a nucleus when the N/Z ratio is less than the stability range (where N=number of neutrons and Z=number of protons in a nucleus. )

Atomic number is the sum of number of protons and neutrons.

If A,Z and N denote the mass number, the atomic number, and the neutron number for a given nucleus, we can say that.

If A,Z and N denote the mass number, the atomic number, and the neutron number for a given nucleus, we can say that.

Staements I: Light nuclei are most stable if N =Z, while heavy nuclei are more stable if N gt Z. (N rarr number of neutrons, Z rarr number of protons) Staements II: As the number of protons increases in a nucleus, the Coulomb's repulsive forece increases, which tends to break the nucleus apart. So, to keep the nucleus apart. So, to keep the nucleus stable, more number of neutrons are needed which are neutral in nature.

Which of the following are true for an element ? (i) Atomic number = number of protons + number of electrons (ii) Mass number = number of protons + number of neutrons (iii) Atomic number = number of protons = number of neutrons (iv) Atomic number = number of protons = number of electrons
