what is atomic mass?
HALOGENS The halogen group (17) is the biggest electronegative in the periodic table, and all elements readily form halide ions X-. Trends in chemistry resemble those collect in
The order of filling of electrons in the orbitals of an atom will be : (1) 3d, 4s, 4p, 4d, 5s, (2) 4s, 3d, 4p, 5s, 4d (3) 5s, 4p, 3d, 4d, 5s
The postulate of Bohr theory that electrons jump from one orbit to the other, rather than flow is according to : (1) The quantisation concept (2) The wave nature of elect
Every substance poses exact amount of energy known as internal energy or intrinsic energy (E).
