Write an expression for the net change in charge if two electrons are added to each of six atoms in a group. Also, write an expression that represents removing two protons each from a group of six atoms.

Given:

Two electrons are added to each of six atoms in a group.

To find:

The expression for the net change in charge.

Solution:

Charge of atoms = Number protons - Number of electrons.

Let number of atoms be x.

6 atoms = 2 electrons added

1 atom = electrons added

1 atom = electrons added

x atoms = electrons added

Therefore, the net change in charge is represented by the expression because we subtract number of electrons to find atom charge, where, x is the number of atoms.

6 atoms = 2 protons removed

1 atom = protons removed

1 atom = protons removed

x atoms = protons removed

Therefore, the net change in charge is represented by the expression , where, x is the number of atoms.
