In any one orbital there is only one way to arrange the two electrons and that is with opposite spin. (Paulis exlusion principle)
In the 3 different p orbitals you could arrange 2 electrons without spin pairing in the same orbital in 3 ways,
The middle two are the same.
The same applies to d orbitals
20 electrons
42 electrons
there are 10 electrons.
how many valence electrons does chalcogens have
Two electrons from each element are shared; the total is four electrons.
I'm not sure this question has any meaning. That is, the words each mean something, but when you arrange them in this way, it's sort of like asking what color five is.
You can arrange and rearrange the word as many times as you like!There are 5040 different ways.
You can arrange 4 in 2 ways 1x4 and 2x2.
you can arrange 8 pictures 28 different ways
you can arrange three beads 9 different ways.
There are two syllables in the word arrange. The syllables of the word are ar-range.
In order to determine the number of electrons in the outer orbit/ valence electrons of a metal, first the total number of electrons needs to be determined. This is done by deriving the atomic number from a periodic table. Arrange these in the shell format of 2, 8, 18, 32... The number of electrons in the outermost shell are the valence electrons
