Answer:
The total charge on atom is -2.
Step-by-step explanation:
We are given the following in the question:
Electrons have a negative charge.
Let this charge be represented by -1.
Protons have a positive charge. Let this charge be represented by +1.
An atom have 2 more electrons than protons.
Let be the number of protons.
Then, the number of electrons are
Total charge on atom =
=Charge on atom = Charge of protons + Charge of electrons
Thus, the total charge on atom is -2.
Hey there!☺
When you are solving an equation, it is important to use <em>inverse</em> operations. You will need to use the <em>inverse</em> operations on both sides of the equation. And it is also important to isolate the variable. After you do that, you will need to reverse it up. The way to do all of this is using the <em>inverse</em>.
To solve an equation, you use <u>inverse</u> operations.
Hope this helps!
