Electrons and protons are particles in an aton with equal but opposite charges. Electrons have a negative charge and protos have a positive charge. What is the charge of an atom with 2 more electrons than protons?

Respuesta :

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 [tex]x[/tex] be the number of protons.

Then, the number of electrons are [tex](x+2)[/tex]

Total charge on atom =

=Charge on atom = Charge of protons + Charge of electrons

[tex]=(+1)(x) + (-1)(x+2)\\=x-x-2\\=-2[/tex]

Thus, the total charge on atom is -2.
