A radioactive nuclide emits `gamma`-rays due to
a. K-electron capture
b. Nuclear transition from higher to lower energy
c. Presence of greater number of neutrons than protons
d. Presence of greater of protons than neutrons

A

K-electron capture

B

nuclear transition from high to lower energy state

C

Presence of greater number of neutrons than protons

D

presence of greater numbe of protons than neutrons

Text Solution

Verified by Experts

The correct Answer is:
b
After `alpha, beta` emission, nucleus goes to excited state, when it returns to normal state, emission of `gamma` radiations takes place.

Q 4 Two atoms are said to be isobars if. * (a) they have same atomic number but different mass number. (b) they have same number of electrons but different number of neutrons (c) they have same number of neutrons but different number of electrons. (d) sum of the number of protons and neutrons is same but the number of protons is different.

Read assertion and reason carefully to mark the correct option. Assertion: Heavy nuclides tend to have more number of neutrons than protons. Reason: In heavy nuclei, as there is coulomb repulsion between protons, so excess of neutrons are preferable.
