What is the quantum number of americium?

Answer 1

1s: ↑↓

2s: ↑↓ 2p: ↑↓, ↑↓, ↑↓

3s: ↑↓ 3p: ↑↓, ↑↓, ↑↓ 3d: ↑ ↑ ↑ ↑ ↑

4s: ↑

It's important to recognize from the above that chromium is an exception to the normal aufbau progression which would predict 1s2 2s2 2p6 3s2 3p6 4s2 3d4, which is to say that you would normally fill the 4s orbital completely with 2 electrons before starting on the 3d which would then have only 4. Copper is another such exception.

Answer 2

1s 2s 2p 2p 2p 3s 3p 3p 3p 4s 3d 3d 3d 3d 3d 4p

Answer 3

The orbital notation of Ce is [Xe]4f15d16s2. This is using the noble gas shortcut. The full notation is the following: 1s22s22p63s23p64s23d104p65s24d105p66s24f15d1.

Answer 4

It is when Souheil combines with Elyas to form A Elyas Baltaji. Simple.

Answer 5

The quantum number of americium is 8S7/2 (it is impossible to write correct on WA).

Answer 6

The electron configuration of californium is: [Rn]5f10.7s2.

Answer 7

Ground state electronic configuration of americium: [Rn].5f7.7s2.
