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 = [tex]\dfrac{2}{6}[/tex] electrons added
1 atom = [tex]\dfrac{1}{3}[/tex] electrons added
x atoms = [tex]\dfrac{1}{3}x[/tex] electrons added
Therefore, the net change in charge is represented by the expression [tex]-\dfrac{1}{3}x[/tex] because we subtract number of electrons to find atom charge, where, x is the number of atoms.
6 atoms = 2 protons removed
1 atom = [tex]\dfrac{2}{6}[/tex] protons removed
1 atom = [tex]\dfrac{1}{3}[/tex] protons removed
x atoms = [tex]\dfrac{1}{3}x[/tex] protons removed
Therefore, the net change in charge is represented by the expression [tex]-\dfrac{1}{3}x[/tex], where, x is the number of atoms.
Answer:
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).
Step-by-step 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
