What is the charge of a particle having 12 protons and 10 electrons?

Answer 1

The net charge of the particle or atom would be 2+

Since particles in chemistry usually refer to the electrons, protons, and neutrons of an atom, I'm assuming you mean the atoms themselves. A proton has a charge of 1+, an electron a charge of 1, and a neutron has no charge. Since there are 12 protons, the cumulative proton charge would be 12+. The ten electrons make up a 10-charge, which you add together to get the net charge: +12 + (-10)= 2+.

The charge of a particle with 12 protons and 10 electrons would be +2, since protons have a positive charge of +1 each and electrons have a negative charge of -1 each.

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
