Transcript

00:01 Okay, as far as i can tell, something got very wrong with the transcribing of this problem, and it's really choppy.

00:08 But i think what we're supposed to do is when given the element, we have to give the atomic mass.

00:21 We have to give the number of protons, the number of neutrons, the number of electrons, the number of electrons.

00:42 Think that's it.

00:45 And what we've been given is silicon, but i can't actually see what number is up there and cobalt.

00:53 So let me try to figure out what might be there, what is likely to be there.

01:09 So silicon 14.

01:21 There's just like a bunch of numbers.

01:24 Cobalt.

01:34 So the most common isotope of silicon is silicon 28.

01:52 Okay.

01:54 So maybe hopefully that would correspond to something that they would have put up there.

02:01 Right.

02:02 And as silicon is silicon 14, maybe this is what was up there.

02:11 Given that, what would be the atomic mass unit, while the mass is always given right up there.

02:17 So the mass should be 28 in this case.

02:22 The number of protons is always given right there.

02:25 So this should be 14...
