mass number

Average binding energy per nucleon is the total binding energy divided by the mass number of the nucleu..

Emission of alpha particle reduces the atomic number by 2 and the mass number by 4. b - emission advances the atomic number by one unit without changing the mass number. Emission of a - rays affects neither the mass no..

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

Question: Define the following terms: a) Nucleons b) Atomic number c) Mass number d) Nucleus Answer: a) Nucleons: The particles found inside the nucleus i.e., protons and neutrons are called nucleons. b) Atomic number: The number of prot..

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..

When four different atoms are attached to the chiral carbon, priority depends on atomic number. The atom with the highest atomic number gets top priority. If the two atoms are isotopes of the same element, the atom of higher mass number has higher prior..

All isotopes of the same element have the same number of protons, but a variable number of neutrons. The isotopes of hydrogen have the following structures (Fig.9.1)...

Radioactive Decay Series - The emission of a or b - particles from a radioactive element results in the function of new element called daughter element. If the daughter element still has unstable nucleus, it further disintegrates by emitting a or b - particle and produces a new daughter element. Th..

(i) The average binding energy/nucleon for light nuclei like 1 H 1 , 1 H 2 , 1 H 3 is small. (ii) For mass numbers ranging from two to twenty, the sharply defined peaks correspond to nuclei, which are relatively more stable than the neighborhood nuclei. (iii) The binding en..

Isotopes are the different forms of the same element, which have the same atomic number but different mass numbers. The isotopes of hydrogen are protium, deuterium and tritium with mass number 1, 2 and 3 respectively. The relative abundance of thre..
