Where is the nucleus of an atom?

Answer 1

The number of nucleons in an atom can vary. A nucleon is either of the two components that make up an atomic nucleus. That's either a proton or a neutron. Different atoms have different numbers of nucleons, and even different atoms of a given element can have different numbers of nucleons (because of isotopic variation). Let's look an a couple of examples to make our point.

In hydrogen-1, which is the simplest and most common form of hydrogen, there is one proton in the nucleus of the atom. It has 1 nucleon. In hydrogen-2, there are a proton and a neutron in the nucleus, and that's 2 nucleons. In hydrogen-3, there are a proton and two neutrons in that nucleus, and that's 3 nucleons. In helium-3, there are two protons and a neutron in the nucleus, and that's 3 nucleons. You can see what's happening if you think it through.

Answer 2

The nucleus of an atom is located at the center of the atom. It contains protons and neutrons, which make up the majority of the atom's mass. Surrounding the nucleus are the electrons, which orbit around it.

Answer 3

in the bottom Atomic nucleus is at the center of the atom.

Answer 4

The nucleus of an atom is:

The central core of the atom. Containing protons, and usually neutrons.
