So to solve this, there's a lot of questions here, but i'm just going to answer the first question.
00:11
Okay, so we'll calculate b, net charge of h ion here.
00:15
So for a, we have phosphorus.
00:18
Just remember that net charge derived here for a formula is equivalent to a number of protons minus number of electrons.
00:29
Okay, so the number of protons is that's equivalent to the atomic number of the elements.
00:36
So we need a periodic table so that we'll get the number of protons of each ion.
00:42
So we have phosphorus and then the atomic number of phosphorus is 15, right? so it's 15 and we subtract the number of electrons.
00:53
We have 18, so that means the net charge will be equal to negative 3.
00:58
And then for p, we have our gun...
