So for this question, we are asked to identify an element, and we're given a couple clues to help us figure it out.
00:10
So the information that we are given is that it's an anion with a negative 2 charge, and that the anion has a total of 36 electrons.
00:24
So an anion with a negative 2 charge means that that atom or that element gained two electrons to make it a negative 2 charge.
00:45
So from going to a neutral atom to an ion, this negative 2 means that it gained two electrons.
00:56
Right? more electrons an atom gets, the more negative it becomes.
01:05
So we know that as an anion, it had 36 electrons.
01:12
So because it gained two electrons in order to form the anion, the neutral atom would be two electrons less than 36.
01:28
So we will subtract 36 from 32.
01:31
So the neutral atom or the element that we're discussing would have 34 electrons...
