WebIsotopes of an element are atoms with the same number of protons, but a different number of neutrons. Changing the number of neutrons in an atom changes that atom's atomic mass. [2] All matter is made up of atoms in various arrangements. Atoms have protons and neutrons in a dense nucleus at the centre, and electrons in orbitals around the nucleus. WebAn isotope is a compound with the same number of protons and electrons, but different number of neutrons. The three most natural isotopes of Mg are Mg-24, Mg-25, and Mg-26. Mg-24 (12 neurtrons) is 78.9%, Mg-25 (13 neutrons) is 10% and Mg-26 (14 neutrons) is 11.01%, of all the Magnesium found in nature.

WebIsotope Pennies Lab. Introduction: Isotopes are atoms, of a given element, that have the same number of protons, but a different number of neutrons in the nucleus. For example: C-12 and C-14 are carbon isotopes. They each have 6 protons (atomic # = 6), but one has 6 neutrons while the other has 8 neutrons. WebIsotopes are atoms that have the same numbers of protons but different numbers of neutrons. An ion is an atom that has gained or lost electrons, so it now has more or fewer electrons than it does protons. So an ion has a negative or positive charge. All atoms are isotopes and if an isotope gains or loses electrons it becomes an ion.
