subshells and orbitals- copper and chromium

what happens to the energy in subshells as you move away from the nucleus?

energy increases

which orbitals are filled first?

orbitals with the lowest energy

how many electron can you have in the same orbital?

2

what spin must each electron in an orbital have?

opposite spins

in both chromium and copper, how many electrons do they contain in the 4s orbital?

1 electron

when is the 3d subshell more stable

when it is either half full or completely full

is chromiums 3d subshell half full or completely full?

half full

is coppers 3d subshell half full or completely full?

completely full

which subshell are the highest energy electrons in s block found in?

the s subshell

which electrons are the only electrons involved in chemical reactions?

the outer electrons

can elements in a d subshell also be involved in chemical reactions ?

yes
