The chemical behaviour of an atom depends on its:
(A) on the number of protons in the nucleus
(B) on the number of neutrons in the nucleus
(C) on the number of electrons revolving around the nucleus
(D) on the number of nucleons in the nucleus
The chemical properties of an element depend on the atomic number of that element. The chemical properties depend on the number of the electrons and the configuration of the valence electrons of that element.
22. Nucleons are considered to be a mixture of which components?
(A) Mason
(B) Quark
(C) Lepton
(D) Photon
Two types of particles may be considered as main constituents of atomic nuclei, namely the protons (p) and the neutrons (n), jointly called the nucleons.

(B) in monoecious plants
(C) both of the above
(D) in algae
In dicots, the guard cells are kidney bean shaped. The inner wall of guard cell surrounding the stomata are thicker than the outer wall. In monocots, stomata are dumb-bell shaped with thick intervening walls.
