number of neutrons

An equipment in which the nuclear chain reaction is carried out in a controlled manner is called a nuclear reactor. The energy liberated in a controlled manner is used to produce steam, which can run turbines and produce electricity. In nuclear reactors, the nuclear fission is controlled by c..

Nuclear Reactors - An equipment in which the nuclear chain reaction is carried out in a controlled manner is called a nuclear reactor. The energy liberated in a controlled manner is used to produce steam, which can run turbines and produce electricity. In nuclear reactors, the nuclear fission is co..

The atoms of different elements, which have the same mass number but different atomic numbers are called isobars. These have different number of protons but equal sum of number of protons and neutrons..

Isotopes - These are the elements having same atomic number but different mass number. They have the same atomic number because the number of protons inside their nuclei remains the same. The difference in their mass number is due to the difference ..

Mass number of 1 4 C is 14. So 14 g of 1 4 C contain 6.023 x 10 2 3 atoms of 1 4 C = 3.012 x 10 2 0 atoms Number of neutrons in 1 atom of 1 4 C = 14 - 6 = 8 Number of neutrons in 7 mg of 1 4 C = (8 x 3.012 x 10 2 0 ) = 24.1 x10 2 ..

The Nucleus - Rutherford and his co-workers, performed series of scattering experiments and concluded that the entire mass and the positive charge is concentrated in a very small region at the centre of the atom, known as nucleus. The radius of the nucleus is about 10 - 1 5 m i.e., 10 - 5 times tha..

Atomic number = 12 Number of protons = Number of electrons = Atomic number = 12 The nucleus of an atom of an element contains 11 protons and 12 neutrons. Determine the atomic number and mass number of the element..

The existence of negative and positive charges on these materials can be explained on the basis of the structure of the atom. Almost all the mass of an atom resides in a central nucleus which contains a number of tightly packed protons and neutrons..

A symbol represents one atom of an element. Example: H stands for one atom of hydrogen. However, if a symbol has a subscript and a superscript, as given along side, then more in formation can be derived from it...

>The mass of electrons is negligible compared to the mass of the protons. Ordinary hydrogen is the only element that has no neutron in it. According to Bohr electrons revolve around the nucleus in fixed orbits called K, L, M, N etc. The energy of the shells increases as the distance form ..
