All right, so this question asks us to complete the table.
00:05
The first one, uranium 92, 338, number of proton will be equal to z number, which is 92, number neutron will be equal to the atomic number minus 92, atomic mass minus 92, which is equal to 146, number of electrons.
00:26
This is a neutron one, some number of electron will be equal to.
00:30
Proton which is 92.
00:32
Now the second one, atomic number is 20 and that is calcium 2 plus 20 and the atomic mass would be the sum of this which is 40.
00:52
Number of electrons will be equal to 20 minus 2 because it's a 2 plus cation is 18.
00:59
The next one molecule number of 23, that is vanadium...
