The "dense" central portion of an atom is called the nucleus. The nucleus of an atom contains neutrons and protons.
A PH3 molecule has a triangular pyramidal shape. The central atom is the Phosphorus atom, which is connected to three Hydrogen atoms.
CARBON
The electron is the part of the atom that accounts for electricity.
The water molecule is one oxygen atom connected to two separate hydrogen atoms. The three are not in a perfect straight line, though there is symmetry through the central oxygen atom.
I'm not really sure if it's called a HUB, but I do know that the central core of an atom is called the nucleus, and is made out of protons (with a positive charge) and neutrons (with no charge).

The nucleus.
In the nucleus of an atom, the positively charged particles are called Protons.
The nucleus is the central part of the atom. (It's in the center)
a nucleus cant be a central atom. the nucleus is part of the atom. you are probably talking about why certain atoms are central atoms in a molecule and why some arent. the answer to that question is that the more electronegative atom will always appear as a central atom.
The central part or the nucleus
The central part of an atom is called the nucleus. It contains protons and neutrons, surrounded by orbiting electrons.
the mitochondria
The nucleus is the central part of the atom. (It's in the center)
The part of the atom that contains neutrons and protons is called the nucleus.
the small part of an atom is a subatomic particle so that's what my science teacher says your welcome :)
