Answers
Explanation:
Isobar, in nuclear physics, any member of a group of atomic or nuclear species all of which have the same mass number—that is, the same total number of protons and neutrons. ... Thus, chlorine-37 and argon-37 are isobars.
Answer:
1. Isobars are atoms of different chemical elements that have the same number of nucleons. Correspondingly, Isobars differ in atomic number (or the number of protons) but have the same mass number. EXAMPLES: 40 S, 40 Cl, 40 Ar, 40 K, 40 Ca.
2. According to Rutherford's model an atom consists of: The centrally located nucleus: The nucleus is a centrally located positively charged mass. The entire mass of the atom is concentrated in it. ... The outer circular orbits: Electrons revolve in circular orbits (shell) in the space available around the nucleus.
4. The distribution of electrons in different orbits or shells is governed by a scheme known as Bohr bury scheme. The arrangement of electrons in various energy levels of an atom is known as the electronic configuration of the atom. According to this scheme. ... The third shell can accommodate as many as 18 electrons.
5. Nucleons are the protons and neutrons in the nucleus of an atom. Protons are positively charged particles, and neutrons have no charge. Protons are slightly less massive than neutrons. The nucleons make up most of the mass of an atom.
