Which particle is not found in the nucleus?

Atoms are the building blocks of matter. Atoms are made up of electron, neutron and proton particles. Electrons are negatively charged, neutrons are neutral and protons have a positive charge.


Three particles that make up an atom?

Atoms consist of negatively charged electrons , positively charged protons and electrically neutral neutrons.


Describe the charges and types of particles that make up all atoms?

The three particles that make up an atom are:electron,proton and neutron. ELECTRON has a negative charge PROTON has a positive charge and NEUTRON has a neutral charge i.e, it contains an equal number of positive and negative charge


Where are the subatomic particles found in an atom?

the particles that make up an atom are; a proton/protons a neutron/neutrons an electron/electrons these are also made up of other particles but to go any further into this subject would require that you have at least a basic understanding of quantum mechanics and these particles are not important at any educational level below degree level (generaly speaking)


What is the subatomic particle discovered by Chadwick?

In 1932, James Chadwick discovered the neutron. Neutrons help stabilize the protons in the atom's nucleus. Because the nucleus is so tightly packed together, the positively charged protons would tend to repel each other normally. Neutrons help to reduce the repulsion between protons and stabilize the atom's nucleus. Neutrons always reside in the nucleus of atoms and they are about the same size as protons. However, neutrons do not have any electrical charge; they are electrically neutral.
