What are isotopes and how do they differ from each other?
WebThe commonly used heavy isotopes are 13 C, 15 N, 18 O, and 2 H, with 2 H being less popular due to the potential risk of varying LC retention times of the same peptide modified with a different number of deuterium atoms (Boutilier et al., 2012; Di Palma et al., 2011; Koehler et al., 2015; Zhang et al., 2002), which is caused by the differential ... WebJul 25, 2014 · Isotopes differ in the number of neutrons; in ions the number of electrons is different from the number of protons.

Atomic number, atomic mass, and isotopes - Khan Academy
WebAnswer: Isotopes are atoms with the same number of protons but that have a different number of neutrons. Since the atomic number is equal to the number of protons and the atomic mass is the sum of protons and neutrons, we can also say that isotopes are elements with the same atomic number but different mass numbers. WebAll other radioisotopes have half-lives under 20 seconds, most less than 200 milliseconds. ... The least stable isotope is 8 C, with a half-life of 3.5(1.4) × 10 −21 s. Light isotopes tend to decay into isotopes of boron and heavy ones tend to decay into isotopes of ... The quantities of the different isotopes can be measured by mass ...
