00:00:01.129 --> 00:00:04.469 A:middle L:90%
I will work on problem 62 from chapter four.
2
00:00:06.040 --> 00:00:11.250 A:middle L:90%
This problem were asked about some notation or an isotope
3
00:00:11.470 --> 00:00:16.320 A:middle L:90%
. And what did the superscript and subscript represent in
4
00:00:16.320 --> 00:00:19.059 A:middle L:90%
the example that were given here is for TASI,
5
00:00:19.059 --> 00:00:26.739 A:middle L:90%
um, with 40 and 19. So the superscript
6
00:00:26.750 --> 00:00:42.880 A:middle L:90%
40 represents Ah, mess number and the's sub script
7
00:00:42.890 --> 00:00:54.960 A:middle L:90%
19 represents atomic number. So another these air the
8
00:00:54.960 --> 00:01:00.700 A:middle L:90%
terms but mass number means a number of neutrons,
9
00:01:02.539 --> 00:01:08.120 A:middle L:90%
uh, neutrons, plus protons, whereas atomic number
10
00:01:08.120 --> 00:01:11.939 A:middle L:90%
is just the number of protons.
