Nucleus of an atom whose atomic mass is 24 consists of
1 11 electrons, 13 protons and 11 neutrons
2 11 electrons, 11 protons and 13 neutrons
3 11 protons, 13 electrons
4 11 protons, 13 neutrons
Explanation:
Nucleus does not contain electron. So the only possible option is (4)

Which of the following statements are correct? I. Atoms of isotopes have same electronic structure. II. Atoms of isotopes occupies same place in periodic table. III. Atoms of isotopes have same number of protons. IV. Atoms of isotopes have same number of neutrons.
1 I and II
2 I, II and III
3 I, II, III and IV
4 II and IV
Explanation:
Isotopes have same atomic number. In atoms number of electrons and protons are equal. The chemical properties of elements depend on their electronic structure. As the atoms of isotopes have identical electronic structure they have identical chemical behaviour and are placed in the same location in the periodic table.

Which one of the following pairs of nuclei are isotones?
1 \(_{34}S{e^{74}}{,_{31}}G{a^{71}}\)
2 \(_{42}M{o^{92}}{,_{40}}Z{r^{92}}\)
3 \(_{38}S{r^{84}}{,_{38}}S{r^{86}}\)
4 \(_{20}C{a^{40}}{,_{16}}{S^{32}}\)
Explanation:
Nuclei of \(_{34}S{e^{74}}\,and{\,_{31}}G{a^{71}}\) are isotones as \(A - Z = 74 - 34 = 71 - 31 = 40\)
