Protons and neutrons make up most of the mass of an atom. Electrons weigh almost nothing by comparison.


What kind of subatomic particle does not make up the nucleus of an atom?

Electrons do not make up the nucleus of an atom. They orbit the nucleus at various energy levels.


What are particles that make an atom?

the particles that makes up an atom are protons neurons electrons among which electrons are the smallest.


Does electrons make up an atom nucleus?

No, the electrons are around the nucleus, not in the nucleus.


Are electrons and protons part of atom?

Yes, electrons and protons are both part of an atom. Electrons are negatively charged particles that orbit the nucleus of an atom, which contains protons (positively charged) and neutrons (uncharged). Together, these particles make up the structure of an atom.


How do we know what parts make up the atom?

An atom contain protons, neutrons and electrons.


Which part of an atom make up most of the size?

The electron cloud makes up most of the size of an atom. Electrons are found in regions around the nucleus, and their movement creates a cloud-like structure that extends far beyond the nucleus itself.


What is smaller than a atom?

Neutrons, protons, and electrons make up an atom, so they are smaller.


What parts of an atom makes up all the mass of an atom?

The nucleus is the part of an atom that contains practically all its mass. In the nucleus, you can find the proton and neutron. The number of electrons, which move about the nucleus, is equal to the number of protons.


What are the two particles which make up an atom called?

What types of particles make up carbon atom?

A carbon atom is made up of six neutrons and six electrons.


What part of the atom is attributed most of the atom's size?

The nucleus. The nucleus contains both of the protons and neutrons of an atom, and make up more than 99% of the atoms matter and weight. If size is talking about measurements of width and space taken up, the outer ring of the atom, the electrons, span out away from the nucleus, orbiting it in an elliptical shape. The electrons of an atom are not physically attached to the atom, and can be arguably not part of the specific atom because the electrons can become intertwined with other atoms' electrons.
