Electrons in Atoms and Ions Flashcards
1
Q
orbital
A
a region around the nucleus of an atom that can hold up to 2 electrons with opposite spins

Q
what is unique about how the subshells fill for chromium and copper?
A
they fill 3d subshell over 4s subshell (i.e. 4s gives 3d 1 electron)

Q
how does energy level change as period number increases and why?
A
- energy increases
- as period number increases, number of shells increases and orbitals within it get larger so electrons further away from nucleus
