The mass number of a nucleus is
1 always less than atomic number
2 always more than atomic number
3 equal to atomic number
4 sometimes more than and sometimes equal to atomic number
Explanation:
D The mass number of a nucleus is defined as the total number of protons and neutrons in an atomic nucleus. It is equal to atomic number but sometimes it is more than atomic number depends upon the number of neutrons.

In sun, the important source of energy is
1 proton-proton cycle
2 carbon-nitrogen cycle
3 carbon-carbon cycle
4 nitrogen-nitrogen cycle
Explanation:
A In the sun, the important source of energy is proton- proton cycle. According to this cycle nuclei of hydrogen through many reactions fuse to form nucleus of helium and in this process huge amount of energy is released.

Which one of the following statements is correct?
1 Only electrons reside inside the nucleus of an atom
2 Both electrons and protons reside inside the nucleus of an atom
3 Only neutrons reside inside the nucleus of an atom
4 Both protons and neutrons can reside inside the nucleus of an atom
Explanation:
D The nucleus contains protons which have a positive charge equal in magnitude to the electrons' negative charge. The nucleus may also contain neutrons which have virtually the same mass but have no charge.
