It contains the nucleons (protons and neutrons)
the denser part of an atom is the nucleus. about 99% of the mass of an atom is concentrated within the atom.
An atom's nucleus contains protons and neutrons, which are the subatomic particles that make up the majority of an atom's mass. The nucleus is the central core of an atom where these particles are located, surrounded by the electron cloud.
nucleus
The central area of an atom is called the nucleus. It contains protons and neutrons, which are tightly bound together. The nucleus makes up the majority of an atom's mass and is surrounded by a cloud of electrons.
The nucleus of an atom contains protons and neutrons, while the electron cloud surrounds the nucleus and contains the electrons. The nucleus is positively charged and is much smaller in size compared to the electron cloud. The electron cloud determines the size of the atom and contains most of the atom's volume.
An atom contains protons and neutrons in the nucleus (though Hydrogen does not have neutrons) and electrons orbiting the nucleus.
The nucleus, made up of protons and neutrons, contains most of an atom's mass.
the nucleus is the center of an atom that contains the positively charged protons and the neutrally charged neutrons. It contains most of the mass of the atom.

The nucleus contains the mass.
The "dense" central portion of an atom is called the nucleus. The nucleus of an atom contains neutrons and protons.
It is the nucleus. It is the middle of the atom
The nucleus of a helium atom contains two protons and two neutrons.
It contains protons and neutrons and no electrons.
