In what world regions are the hearths of the indo-european languages?

Originally in Anatolia, but spread around Europe (hence the name Indo-European)

Explanation:

A hearth is where something originated from. So the beginning of a branch of languages starts with a single language that evolves into different dialects and vocabulary to form a different language branched off from the original.

because the two particles have an equal charge, the charges will cancel out and give the atom an overall charge of 0. so, if at atom has 35 protons in the nucleus, we could expect it to have 35 electrons orbiting that nucleus.
