Define atomic number, mass number, isotopes, isobars, isotons, isoelectronic species
Answers
Answer:
atomic number: the number of protons in the nucleus of an atom, which is characteristic of a chemical element and determines its place in the periodic table.
mass number: the total number of protons and neutrons in a nucleus.
isotopes: Isotopes are variants of a particular chemical element which differ in neutron number, and consequently in nucleon number. All isotopes of a given element have the same number of protons but different numbers of neutrons in each atom
isobars: each of two or more isotopes of different elements, with the same atomic weight
isotons: Two nuclides are isotones if they have the same neutron number N, but different proton number Z. For example, boron-12 and carbon-13 nuclei both contain 7 neutrons, and so are isotones.
isoelectronic species: Isoelectronic species are elements or ions that have the same, or equal number of electrons. This module explores that although isoelectronic species have the same number of electrons, they are different in their physical and chemical properties.
