Based on the atomic number, mass number, and neutron number of the element, three things can be considered. These are isotope, isobar, and isotone. The number of neutrons depends on the isotope of the atom. Number of protons, electrons and … Meer weergeven An atom is the smallest particle of an element that has no independent existence but is directly involved in chemical reactions as the smallest unit. Atoms are so … Meer weergeven When an atom carries a negative or positive charge by accepting or rejecting electrons, it is called an ion. The ionic properties of the elements depend on the exchange of electrons. In an atomic ion only the … Meer weergeven Atoms that have the same number of protons but different mass numbers are called isotopes of each other. The English chemist Frederick Sodi first came up with the idea of … Meer weergeven An atomic number is a number that carries the properties of an element.
