Questions that came up during the presentation:
When will the first ground state atom with 'g' electrons appear in the periodic
table?
Response: I think it is most likely that the element with an atomic number
of 121 will be the first element with a 'g' electron. Why? The first 'd'
subshell occurs in the n = 3 level, but does not appear until after the
4s sublevel. Electron configurations are written as ns2(n-1)dx
(where x is a variable). The first 'f' subshell occurs in n = 4 level, but
does not appear until after 6s sublevel. Electron configurations are written
as ns2(n-2)fx(n-1)dx. So following the
same pattern a 'g' subshell occurs in the n = 5 level, so it would be expected
to occur following the 8s sublevel. The electron configuration would be;
ns2(n-3)gx(n-2)fx(n-1)dx.
Why do the melting point fo rthe alkali metals decrease as you go down the
group and the boiling points of the halogens increase?
Response: coming soon.
I think there was one more question I was going to answer. Anyone remember
what it was? Send me an e-mail.
