It depends on what you mean by what parts are equal. Protons and electrons both have the same magnitude of charge with opposite signs and electrons are much less massive than protons. Protons and neutrons are approximately equal in mass but protons have a charge of +e Coulombs while neutrons have a charge of 0. Atoms can often exist with unequal numbers of protons and electrons. Such atoms are called ions and have a negative charge if they have more electrons than protons and positive charge if they have more protons than electrons.

From 1 to 12 the numbers add to 78. If each of the 3 parts has to be equal then they must add up to 26 (a third of 78). I think the closest you will be able to get is 25, 26, 27.
Yes the ratios are sometimes equal to each other.
yes and they intersect at 90degree each diagonal divides the other diagonal in 2 equal parts
28 can be split equally into: 2 equal parts of 14 each 4 equal parts of 7 each 7 equal parts of 4 each 14 equal parts of 2 each

An atom is electrically neutral because it has an equal number of protons (positive charge) and electrons (negative charge). The protons and electrons balance each other out, resulting in no overall charge for the atom.
The number of protons and electrons in a neutral atom must always be equal, as they balance each other out. This equivalence ensures that the atom has no overall charge.
The number of protons in an atom is equal to its atomic number.
balanced
A free atom has no electrical charge because it has an equal number of protons and electrons. Each proton has a single positive charge, and each electron has a single negative charge. These balance each other and the result is a net neutral atom (or no net charge).
there is an equal number of positive and negative charges which exactly cancel each other out.
An atom's atomic number IS the number of protons it has. The number of protons and electrons are equal to each other also. Illustrate and explain why?
equal symmetry
An atom has a neutral charge because the number of protons in the nucleus, which are positively charged, is equal to the number of electrons orbiting around the nucleus, which are negatively charged. The positive and negative charges cancel each other out, resulting in a neutral overall charge for the atom.
Divide each side into three equal parts. Then join the division marks on opposite sides with straight lines parallel to the other side(s).
