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.
Answer:
Step-by-step explanation:
1) 4(2a+p)=c+p+a
2) Expand: 8a+4p=c+p+a
3) subract a and 4p: 7a=c-3p
4) Divide: a=
