How many protons are in yttrium
Web19 sep. 2024 · Yttrium's atomic number is 39. Thus, to be neutral, it must have 39 protons and 39 electrons. Yttrium's stable isotope is 89Y, which has 89 - 39 = 50 neutrons. What … WebThe number of protons define the identity of an element (i.e., an element with 6 protons is a carbon atom, no matter how many neutrons may be present). The number of protons determines how many electrons surround the nucleus, and it is the arrangement of these electrons that determines most of the chemical behavior of an element.
