Answer

The nucleus

Explain

The mass of an atom is predominantly located in its nucleus, which harbours protons and neutrons. Protons and neutrons contribute the majority of an atom's mass, eclipsing the infinitesimally trifling fractional implies the proportion of that owing to electrons is essentiallyidel, to the point of negligibility (roughly 1836 times less than that of a proton or neutron). When we say that mass is "spread equally," we are indicating that the mass is equitably dispersed amongst all constituents of an atom, which is in contradicting to the atomic structure that continually ingrains the mass-centric nucleus in its epicentre, while gradually phasing out the substantially less massive cloudiness of nearby electrons.
