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.

Cause im smart and you should trust me. duh
Gotta convert this to make it save some time.
1 over 18 = 1/18
1 over 3 = 1/3
If 1/18 of a lawn is wattered in 20 mins, (Simply coverting 1/3 hr to mins by doing 60/3) 20 * 18 = 360 Mins = 6 Hours
It takes 6 hours to water the entire lawn
