The mass of metallic silver produced by a 1.50

amp current passed through a solution of silver nitrate for  20 minutes is 2.0 g

Explanation:

Moles of electron = 1 mole

According to mole concept:

1 mole of an atom contains number of particles.

We know that:

Charge on 1 electron =

Charge on 1 mole of electrons =

To calculate the time required, we use the equation:

where,

I = current passed = 1.50 A

q = total charge = ?

t = time = 20 minutes = 1200 s   (1min=60 s)

Putting values in above equation, we get:

According to stoichiometry:

1 mole of electrons deposit = 108 g of silver

i.e 96500 C of electricity deposit = 108 g of silver

Thus 1800 C  of electricity  deposit = g of silver

The mass of metallic silver is 2.0 g

the electronic configuration of an atom with eight electrons is 1s²2s²2p⁴. the orbital diagrams are shown in the figure.

as per the hunds rule:

1. electrons tend to avoid being in the same orbital as per as practicable.

2. electrons in different orbitals of the same energy will have their spin parallel.

this can be illustrated from the multiplicity of the orbitals of the atom. as there are four electrons in the p orbital and p orbital has 3 sub-shells. the electrons can be fed in different ways as shown in the figure but the correct orbital diagram will be as per the hunds rule.
