number of protons

Naturally occurring radioactive substances have high nucleon number. It is possible to make artificial radioactive substances by bombarding lighter nuclides with - particles, protons or neutrons. The radioactive substances produced in this manner are known as radioisotopes. A nu..

Hydrogen atom (Z = 1) has no neutrons. Number of protons = 1Number of electrons = 1Number of neutrons = 0It has been reported that the hydrogen element has atoms with mass number 2 and 3 also i.e., Atoms of elements having the same atomic numb..

Rate of reaction Protons and neutrons Nuclear forces Electromagnetic repulsion between the protons Nuclear fusion and fission reactions Radioactive isotopes Three most common forms of radioactive decay (alpha, beta, gamma) Changes in the nucleus in each type of deca..

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 three isotopes in nature..

The discovery of the electron, proton and neutron was the starting point of new avenues of research in science, which gave physicists an insight into the structure and nature of the atoms of matter. An atom is made up of three elementary particles, namely electrons, protons..

>Lead-214 decays with the emission of a - particle. The equation for charge is 82 - (-1) = 82 + 1 = 93. But the nucleus is supposed to be made up of protons and neutrons only, so how can a - particle be emitted? A neutron in the nucleus has changed into a proton by emitting an e..

An atom is made up of three particles, electrons protons and neutrons. Electrons have a negative charge and protons have a positive charge whereas neutrons have no charge. They are neutral. Due to the presence of equal number of negative electrons and positive p..

Introduction - The reactions of amines are mainly due to participation of unshared pair of electrons of nitrogen which makes them react as a nucleophile or a base (A nucleophile is a species that attacks an electron - deficient carbon and a base is a species that attacks an electron deficient hydro..

Mass Energy Relation - Einstein derived a formula given the relation between mass and energy as E = mc 2 . Here 'm' is the mass, 'c' is the velocity of light and 'E' is the energy. This equation has given equal states to mass and energy. It states that a mass m has energy E given by the above formu..

At present we know that the atom is the smallest particle of an element, which may or may not have independent existence. It is made up of sub-atomic particles like electrons, protons and neutrons. Atoms of one type of element differ from those of the other due to different number..
