Question

GIve two examples in each case
i) Monovalent Cation
ii) divalent cation
iii) trivalent cations
vi) trivalent cation
v) Monovalent anion
vi) divalent anion
vii) trivalent anion
viii) tetravalent anion.

Answer 1

Hint: Cations are positively charged ions (atoms or organizations of atoms that have greater protons than electrons because of having misplaced one or greater electrons). Anions are negatively charged ions (which means they have got greater electrons than protons because they have won one or greater electrons).

Complete Answer:
The ions have a contrary electric charge, consequently they get interested in every different. Cation repels different cations while anion repels every other anion. The variety of protons is extra than the variety of electrons in a cation while the variety of electrons is extra than the variety of protons in an anion.
Two examples of monovalent cation are: \[L{i^ + },{\text{ }}N{a^ + }\]
Two examples of divalent cation are: \[M{g^{2 + }},{\text{ }}C{a^{2 + }}\]
Two examples of trivalent cation are: \[A{l^{3 + }},{\text{ }}A{u^{3 + }}\]
Two examples of tetravalent cation are: \[S{i^{4 + }},{\text{ }}P{b^{4 + }}\]
Two examples of monovalent anions are: \[C{l^ - },{\text{ }}B{r^ - }\]
Two examples of divalent anions are: \[{O^{2 - }},{\text{ }}{S^{2 - }}\]
Two examples of trivalent anions are: \[P{O_4}^{3 - },{\text{ }}{P^{3 - }}\]
Two examples of tetravalent anions are: \[S{i^{4 - }},{\text{ }}{C^{4 - }}\]

Note:
Ions which can be part of the technological know-how issue Chemistry paperwork from atoms and electrons which have both won or misplaced their weight via means of the elimination or including of 1 or extra valence electrons which might create both superb or a bad rate. The ions with a bad rate are referred to as anions and those with a superb rate are referred to as cations. Since each of them has costs of opposing qualities, they get drawn to each other and thereby form an ionic bond among them.
