Question

what is valancy of magnease​

Answer 1

Answer:

25 7

ElementAtomic NumberValencyValency of Manganese257, 4, 2Valency of Iron (Fe)262, 3Valency of Cobalt273, 2Valency of Nickel282

Answer 2

Answer:

2+

Step-by-step explanation:

manganese is a transition metal and hence it can have more than one valency

. the atomic number of manganese is 25 . hence the electronic configuration is [Ar] 3d5 4s2.

and hence it requires 2 electrons therefore the valency is 2+. note that it can have more than ne valency .
