Do you mean the electrons? They have a negative charge
Valence electrons occur in the outermost energy level, or valence shell, of an atom. These electrons are involved in the formation of chemical bonds and determining the atom's reactivity and chemical properties.
Depends, but it is probably electron
Rutherford discovered the atomic nucleus and the proton. A short answer for the Rutherford atomic model: the atom is composed from a central part - a nucleus, positively charged, surrounded by electrons - very small negative charged particles.
Electrons - the valence electrons
None - because electrons are part of the atom.

The Protons (in the nucleus).
An atom has a negative part (called electrons) because it has a positive part also (called protons), so the electrons make it electrically neutral.
Electrons - the valence electrons
Nucleus does not have electrons in it. It contain protons and neutrons.
