What element has 2 protons neutrons? Heliumis the second element of the periodic table and thus is an atom with two protons in the nucleus. Most Helium atoms have two neutrons in addition to the protons. In its neutral state, Helium has two electrons in orbit about the nucleus. Model of ...
Until 1897, scientists believed that there was no smaller unit of matter in existence than the atom. This changed when J.J. Thomson first discovered the electron, proving the existence of subatomic particles. Later, scientists would also discover protons and neutrons. ...

The meaning of PROTON is an elementary particle that is identical with the nucleus of the hydrogen atom, that along with the neutron is a constituent of all other atomic nuclei, that carries a positive charge numerically equal to the charge of an electro

The number of electrons in an electrically neutral atom is also equal to the atomic number, Z. The total mass of an atom is determined very nearly by the total number of protons and neutrons in its nucleus. This total is called the mass number, A. The number of neutrons in an atom, ...
Why neutrons and protons are modified inside nuclei The structure of a neutron or a proton is modified when the particle is bound in an atomic nucleus. Experimental data suggest an explanation for this pheno... G Feldman - 《Nature》
This reduces to a cubic equation in the symmetric case of an equal number of protons and neutrons. Qualitative features of the solution can be followed without an explicit solution of this equation, and explicit expressions are given for the excitation spectrum at the Fermi level. The method is...
The protons and neutrons live in the nucleus, while the electrons are orbiting the nucleus similar to the way planets orbit a star. (We’ll see in a later video the various orbits these electrons can occupy.) In a neutral atom, the number of positively-charge protons must equal the number...
Today we know that protons (and neutrons) are formed from even smaller particles, quarks, and that the nucleus of an atom is made from protons and neutrons (with the exception of the basic form of hydrogen, which has no neutrons). What is the charge of a proton? A proton has what is...
