Under most conditions, an atom has the same number of protons and electrons. True or False

True! Under most conditions, they are usually the same.

This is because to balance out the negativity or positivity of an atom, the opposite joins in.

Hope this helps.

since the atomic number is the number of protons in the nucleus, as we move to the left on the periodic table, the electrostatic pull between the nucleus and the valence electron shell decreases. as we move down a group (vertical column), the valence shell energy level gets further and further from the nucleus.
