Electrons and protons are particles in an aton with equal but opposite charges. Electrons have a negative charge and protos have
1 answer:
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.

I show an example in the picture below. If you know how to solve with Pythagorean theorem this problem should be fairly easy. All you have to do is make 2 triangles and solve for C. Once you solve for C for both triangles you should get 20 for one answer and 15 for the other answer. Then all you do is just add them together so your answer should be 35 feet.
