What is :-
a) Valence orbit/shell
b) Valence electrons
C) Valency
Answers
Explanation:
(a) The number of electrons in the outermost shell of a particular atom determines its reactivity, or tendency to form chemical bonds with other atoms. This outermost shell is known as the valence shell, and the electrons found in it are called valence electrons.
(b) In chemistry and physics, a valence electron is an outer shell electron that is associated with an atom, and that can participate in the formation of a chemical bond if the outer shell is not closed; in a single covalent bond, both atoms in the bond contribute one valence electron in order to form a shared pair.
(c) the combining power of an element, especially as measured by the number of hydrogen atoms it can displace or combine with.
Answer:
heya mate ☺
✏ Valence shell = last shell .
✏ Valence electron = electrons iN the last shell .
✏ Valency = combining capacity of an electron .
hope it helps u mate ⛄
