Question

Arrange the following into monovalent, bivalent, trivalent, tetravalent cations.
A) Stannic
B) Nickel
C) Antimonous
D) Cuprous​

Answer 1

Answer:

nickel the correct answer

Answer 2

a) Ammonium (NH

4

+

):

It is a monovalent cation as it has a charge of +1 i.e it haas lost one electron so it has an excess of protons.Hence, it is positive.

b) Oxide (O

2

−):

It is a divalent anion as it has gained two electrons to attain the state of −2 charge. After gaining two electrons, it has more electrons in its atom than protons, hence it has a negative charge.

c) Nitride (N

3

−):

It is a trivalent anion as it carries a charge of −3 on nitrogen. Here, the nitrogen atom has gained 3 electrons to attain the state of −3 as there are more electrons in its atom now than protons.
