an atom with too many protons can decay by

Since the atom is electrically neutral there had to be positively charged particles present in the atom to neutralize the negative charge of the electron..

Alpha decay is the phenomenon of emission of an a - particle from radioactive nucleus...

Production of anode rays - Since the atom is electrically neutral there must be positively charged particles present in the atom to neutralize the negative charges of the electrons. Goldstein experimentally proved the existence of protons in the atom..

Nuclear Stability and Neutron/Proton Ratio - It has been found that the stability of nucleus depends upon its neutron to proton (n/p) ratio. A plot of N (the neutron number) against Z (atomic number or number of protons) show that for stable nuclides upto Z =..

b - particle, and reverts to nitrogen In nature, radiocarbon is formed when high energy atomic particles called cosmic rays break down the atoms in the atmosphere into electrons, protons, neutrons and other particles. Some of the neutrons strike the nuclei of ni..

A radioactive nucleus or element emits an alpha or a beta particle and gets converted into a new nucleus or element. The process of destruction of the original nucleus during the formation of new nucleus due to radioactivity is called Radioactive decay or disintegration. When a α..

Atom is the smallest particle of an element, which may or may not have independent existence. It is made up of subatomic particles like electrons, protons and neutrons. Atoms of one type of element differ from those of the other due to different number of subatomic pa..

Gamma decay is the phenomenon of emission of gamma ray photon from a radioactive nucleus...

Rate of Radioactive Decay - The spontaneous breaking up of the nucleus is known as radioactive disintegration or radioactive decay. Radioactive disintegration is found to obey the following two laws: i) Atoms of all radioactive elements are undergoing spontaneous disin..

;). For Balmer series, n 1 = 2, n 2 = 3,4,5,… For Paschen series, n 1 =3, n 2 = 4,5,6… For Brackett series, n 1 = 4, n 2 = 5,6,7…. For P fund series, n 1 = 5, n 2 = 6,7,8…. Total energy of an electron in a stationary orbit is calculated from the relation Atomic..
