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 equal to ..
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 mass m has energy E given b..
Relation Between Atomic Number and Atomic Mass
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 ..

Atomic Number (Z) is the number of protons in the nucleus of an atom. It is also equal to the number of electrons since the atom is electrically neutral. Mass Number (A) is the total number of neutrons and protons present in the nucleus of an atom. The p..

In 1936, Neils Bohr suggested that the nucleus might be like a droplet of dense liquid, composed of sub droplets of protons and neutrons. A uranium nucleus is spherical in shape. In this spherical nucleus, protons and neutrons are together because of the del..
Sub Critical Mass
If the mass of the fissionable material is less than the critical mass then the mass is called sub-critical mass. Note : Neutron is considered to be the ideal bombarding agent because being neutral in charge there is no force of attraction or r..
Order of magnitude of mass
Masses of objects also have values of wide range. They are tabulated as below in the order of magnitude. Object Order of magnitude of length (kg) Electron 10 -31 Proton 10 - 27 Uranium atom 10 - 25 Cell 10 - 10 Earth 10 25 S..
Solution:
Atomic number = number of protons = 11Mass number = number of protons + number of neutrons= 11 + 12 = ..
Example: 2
The nucleus of an atom of an element contains 11 protons and 12 neutrons. Determine the atomic number and mass number of the elemen..

When ever i visit TutorVista, I always leave with a good understanding of what they are teaching me, you guys are wonderful - Anna
My son started joined Tutor Vista in 6 th grade, Now he is 8 th grade, He likes Tutor Vista tutors more than his school teachers…Lucy
My daughter use to study from personal tutor for Maths, but now when she is studying through TutorVista, she gets tutoring for Maths, Science, English.. everything at a price cheaper than the Math tutor she had.
