Mass Energy Relation
Mass Energy Relation - Einstein derived a formula given the relation between mass and energy as E = mc 2 . Here 'm' is the mass, 'c' is the velocity of light and 'E' is the energy. This equation has given equal states to mass and energy. It states that a ..
Atomic Number and Atomic Mass
The nuclei of atoms is made up of protons and neutrons. These two components of the nucleus are referred to as nucleons. The electrons occupy the space outside the nucleus. Since an atom is electrically neutral, the number of protons in the nucleus is exactly equ..
Relation Between Atomic Number and Atomic Mass
While studying the periodic table, it will be noticed that with the increase in the atomic number, there is an increase in atomic mass as well (with some exceptions). Usually an element with high atomic number has high atomic mass as well. If you recall from earlier lessons, At..

The charge and mass of the positive particles
The positive particle from hydrogen is 1837 times heavier than the electron. This positively charged particle was called proton. The proton is produced by the loss of an electron from a neutral hydrogen atom and is thus a hydrogen ion H + . The mass of H is found to be..

Solution:
Atomic number = number of protons = 11 Mass number = number of protons + number of neutrons = 11 + 12 = ..
Nuclear Stability
Surprisingly, the mass of the nucleus is less than the sum of the masses of the individual protons and neutrons which makeup the nucleus. The lost mass (mass defect) has been changed into the energy necessary to bind the nucleus toge..
See what our Users say :
Very fast and clear. Made sure I understood the concepts instead of giving the answers to the problem.
all my questions were answered in a very clear way and i learned a new math rules which i did not know this service is very helpful - mike
I think the tutors knew their stuff really well and was very helpful. math was actually something I dread.not anymore ,Thank you Tutor Vista - jennifer,New york
It is at a nice pace to shoot down all my problems I was having on my assignment. excellent tutoring at affordable cost ...Really amazing,Thank you
