WebNov 14, 2024 · Isotopes 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. shutterstock empty car repairWebFeb 20, 2014 · Feb 20, 2014 The neutron/proton ratio and the total number of nucleons determine isotope stability. NEUTRON/PROTON RATIO The principal factor is the neutron to proton ratio. At close distances, a strong nuclear force exists between nucleons. This attractive force comes from the neutrons. shutterstock eps downloader

"WebJan 15, 2008 · To determine the ages of these specimens, scientists need an isotope with a very long half-life. Some of the isotopes used for this purpose are uranium-238, uranium-235 and potassium-40, each of which has a half-life of more than a million years. Unfortunately, these elements don't exist in dinosaur fossils themselves. " - How do you determine isotopes

How do you determine isotopes

WebIsotopes are atoms of the same element that have different number of neutrons. (In order for them to be atoms of the same element, their number of protons would be the same.) Examples: is an isotope of chlorine that has 17 protons and 18 neutrons. is an isotope of chlorine that has 17 protons and 20 neutrons.
