Eight. The electrons with the highest energy levels are counted as the valence, or outer, orbitals. There are shells that contain more electrons such as D or F shells that can accommodate for 10 and 14 electrons respectively, however they are a lower energy level than their respective S and P shells that fill up before them which hold 2 and 6 electrons equaling a max of 8 outer orbitals.
A maximum of two (when two they are spin paired i.e are of opposite spin).
The valence electrons fill in 4d orbital The electron configuration of yttrium is [Kr]4d15s2.
How many atoms / electron clouds does helium have ?
An electron orbital describes the most probable region that an electron occupies outside the nucleus
There can only be 2 electrons in each single orbital, and they will be on opposite sides of the electron cloud (orbital).
The Specific orbital the electron is in
The M orbital, there's only 1 electron in it.
any time there are as many electrons and protons and they fill each orbital optimally.
The valence electrons fill in 4d orbital The electron configuration of yttrium is [Kr]4d15s2.
How many atoms / electron clouds does helium have ?
An electron in a 2s orbital is on average closer to the nucleus.
It needs to lose one electron so that it can have 8 electrons in its outer orbital
there r 2 electrons in the s orbital, their r 6 electrons in p orbital , their r 10 electron's in the d orbital and 14 electrons in f orbital.
Fluorine in its elemental stage has 1 unpaired electron. ( 2p5 orbital has one unpaired electron in 2p orbital)
The specific orbital the electron is in
Each orbital must contain a single electron before any orbital contains two electrons.
One electron in each of the three p orbitals (Hund's rule)
2 at the most
