atom labeled \y\ in the attached picture?
it is positively charged
it contains most of the volume of the atom
it is the location of the protons
it is neutral
it is the location of the electrons
it is negatively charged
it contains most of the mass of the atom
it is the location of the neutrons

Explanation:

In an atomic model, the central part (assuming 'Y' is the nucleus) contains protons and neutrons. Protons are positively - charged and neutrons are neutral. The nucleus contains most of the mass of the atom as protons and neutrons are much heavier than electrons. Electrons are located outside the nucleus in electron - shells. The nucleus is positively charged due to protons. It does not contain most of the volume of the atom (electron - cloud takes up most of the volume).

Answer:

It is positively charged, It is the location of the protons, It contains most of the mass of the atom, It is the location of the neutrons
