Proton was discovered by E. Rutherford in 1917.
Electron was discovered by J. J. Thompson in 1897.
Neutron was discovered by J. Chadwick in 1932.
All were of English origin.
J. J. Thomson in the late 1800's
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.
Atoms consist of negatively charged electrons , positively charged protons and electrically neutral neutrons.
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
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)
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.
The neutron has no charge. The proton is + and the electrons is -
It is proton neutron in the nucleus and then electrons in the electron cloud.
The three main particles in atoms are a proton which is a positive charge, electron which is a negative charge and a neotron which has no charge at all. Tahlia :)
Atoms have equal numbers of protons and electrons.
An atoms nucleus contains the proton and neutron while the electron cloud contains its electrons
The parts of Atom are Proton, Neutron, and Electron.
Protons and neutrons have almost the same mass.
Loss or gain of electrons.

Proton and neutron.

yes they are what makes up the atom
