Characteristics of Electrons, Protons and Neutrons
Characteristics of Electrons, Protons and Neutrons - Particle Electron Proton Neutron Symbol e p n Nature Negatively charged Positively charged Neutral Relative charge -1 +1 0 Absolute charge 1.6 x 10 -19 C 1.6 x 10 -19 C 0 Relative mass 1/1840 amu ..
Neutron
A neutron is a particle having a mass equal to 1.67 x 10 - 2 4 g (hydrogen atom) and no electrical charg..
Proton
The proton has a mass equal to that of hydrogen atom, which is equal to 1.67 x 10 - 2 4 g or 1.0073 amu while it has an unit positive charge of +1.602 x 10 -19 ..
Discovery of Neutrons
The whole mass of an atom is due to the nucleus, which means that the nucleus must contain protons equal to the mass of the atom. As the number of protons is equal to the atomic number, the atomic mass should be equal to the atomic number. But for ..
Mass of a proton
A proton can be thought of as a hydrogen atom that has lost its electron. Since the mass of an electron is small, the mass of a proton is equal to the mass of a hydrogen atom. As the mass of hydrogen atom is for all practical purposes 1 a..
Nuclear Stability and Neutron/Proton Ratio
It has been found that the stability of nucleus depends upon its neutron to proton (n/p) ratio. A plot of N (the neutron number) against Z (atomic number or number of protons) show that for stable nuclides upto Z = 20, N = 20 i.e., the relationship ca..

A proton is actually a hydrogen atom, which has lost its electron. Since the mass of an electron is small, the mass of a proton is equal to the mass of a hydrogen atom. As the mass of hydrogen atom is 1 a.m.u., the relative mass..
Atomic mass, mass number or nucleon number
The total number of protons and neutrons present in one atom of an element is known as its mass number. Mass number = number of protons + number of neutrons It can also be said that: Mass number = Atomic number + number of ..

Binding Energy and Mass Defect - An atomic nucleus is a stable structure. The nucleus is bound by very strong short range forces called nuclear forces. Certain amount of work has to be done to separate the nucleons to such a distance that there is no interaction. This work done therefore ..

Very good, Tutor was clear and guided me through the whole algebra problems
This Tutor Vista is GREAT! loved this session, it helped me heaps.
Tutor are so organized and neat with their teachings. She set up everything that made the problems more understandable by showing them in such a simple manner, I feel I could really learn from them and pertain it to my class! :)
Thank you very much for helping to me is very important to have my lessons. Because you manage to take good notes in school thank you Tutor Vista
