00:01 So here in this question we're told that we have a bromide ion, which would be br minus, mass number of 79.
00:17 And we can look out from our periodic table, the atomic number for bromine.
00:23 We already have the charge indicated minus one.
00:26 Atomic number here is 35.
00:28 So number of neutrons can be calculated by taking the mass number.
00:36 And subtract the atomic number...
