The isotopes of an element differ in (1) The number of neutrons in the nucleus (2) The charge on the nucleus (3) The number of extra-nuclear electrons ( 4) Both the nuclear charge and the number of extranuclear electrons.

A radioactive decay can form an isotope of the original nucleus with the emission of particles

Originally the radioactive beta decay was thought as a decay of a nucleus with the emission of electrons only (Case I). However, in addition to the electron, another (nearly) massless and electrically neutral particle is also emitted (Case II). Based on the figure below, which of the following is correct:

Why is atomic number always calculated from the number of protons in the nucleus and not from the number of electrons present in the extra nuclear part?

Total number of electrons, protons and neutrons present in the nucleus of ._(92)U^(238) is

A nucleus has atomic number 11 and mass number 24. State the number of electrons, protons and neutrons in the nucleus

In a radioactive decay, a nucleus is transformed into another with the emission of a positron. In this process the neutron-proton ratio

Assertion : In a radioactive disintegration, an electron is emitted by the nucleus. Reason : Electrons are always present inside the nucleus.
