Answer:
(1) name of anion is written first followed by
the name of cation.
(2) name of cation is written first followed
by the name of anion.
(3) valency of cation is written first followed
by the valency of anion.
(4) name of cation and anion are written in
alphabetic order.
Answer:
1) The compounds are named by writing the name of the cation first followed by the name of the anion. For example, KCl, an ionic compound that contains K+ and Cl- ions, is named potassium chloride.
2) There are two rules that must be followed through: The cation (metal) is always named first with its name unchanged. The anion (nonmetal) is written after the cation, modified to end in.
3)Till 10th standard, Since concept of oxidation no. is not introduced to you. You can say if atom gains electron, valency is positive and if it loses electrons its valency is -ve. But 11th standard onwards, we don't talk about valency, we consider oxidation no.
4) Coordination compounds are complex or contain complex ions, for example:
Complex Cation: [Co(NH3)6]3+
Complex Anion: [CoCl4(NH3)2]−
Neutral Complex: [CoCl3(NH3)3]
Coordination Compound: K4[Fe(CN)6].
i think this answer will helpful for you !!!
