What is contained in the nucleus of a atom?

Protons and neutrons. Virtually all of the atom's mass.


The mass of an atom is contained primarily in its?

The mass of an atom is primarily contained in its nucleus, which is made up of protons and neutrons. Electrons, which have a much smaller mass compared to protons and neutrons, occupy the space surrounding the nucleus.


Where is most of the mass of an atom contained?

When calculating the mass of an atom, you add the mass of the protons and the neutrons. This is the nucleus of the atom. The electrons are small enough to be ignored except in the most delicate calculations.


Over 99 percent of the mass of an atom is contained where?

Over 99% of the mass of an atom is contained in the nucleus, where protons and neutrons are located. Electrons, which have negligible mass compared to protons and neutrons, occupy the remaining space in the electron cloud surrounding the nucleus.

Why is are protons and neutrons called subatomic particles?

because they are contained inside the subsection of the atom (nucleus.)


Where are protons and neutrons in an atom?

protons and neutrons are located in the atom's nucleus.


What number of protons and neutrons must be contained in the nucleus to result in a neutral atom?

For a neutral atom, the number of protons (which determines the element) must be equal to the number of electrons. This means that the number of protons should be equal to the number of electrons for the atom to be neutral. Neutrons have no charge, so the number of neutrons does not affect the overall charge of the atom.


What is contained inside the nucleus of an atom?

The nucleus of an atom contains protons and neutrons, which are called nucleons. Protons have a positive charge, while neutrons have no charge. Electrons, which have a negative charge, orbit around the nucleus in electron clouds.
