Question

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.​

Answer 1

Adding two electrons to each of six atoms results in a net change in charge of (-2)(6). Removing two protons from each of six atoms results in a net change in charge of (2)(-6).

Explanation:

I know this is right because i just did the problem and got it wrong then it showed the correct answer and that is the exact answer so you might wanna switch the answer up a little so you dont get in trouble

Answer 2

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 =
`(2)/(6)` electrons added

1 atom =
`(1)/(3)` electrons added

x atoms =
`(1)/(3)x` electrons added

Therefore, the net change in charge is represented by the expression
`-(1)/(3)x` because we subtract number of electrons to find atom charge, where, x is the number of atoms.

6 atoms = 2 protons removed

1 atom =
`(2)/(6)` protons removed

1 atom =
`(1)/(3)` protons removed

x atoms =
`(1)/(3)x` protons removed

Therefore, the net change in charge is represented by the expression
`-(1)/(3)x`, where, x is the number of atoms.
