electrons - subshells/orbitals Flashcards
1
Q
electron cloud
A
region of space where there is a possibility of electrons being found.
2
Q
subshell
A
- all electron shells after the first shell can be divided into subshells, with each shell containing one more subshells than the previous.
- each type of subshell can hold 4 more electrons than the previous
3
Q
orbital
A
region of space in which up to two electrons are likely to be located. orbitals may also be empty
4
Q
bohr’s model
A
further away from the nucleus means more energy
no in between energy level but sub levels to each major level
5
Q
s-subshell
A
- the lowest energy subshelll in every electron shell
- made of one orbital
- hold only 2 electrons
6
Q
p subshell
A
- contains 3 orbitals starting at second shell
- can hold up to 6 electrons in total
7
Q
d subshell
A
- third shell is the first to contain a d-subshell
- each d-subshell contain 5 different orbitals - each hold 2 so 10 in total
8
Q
f subshell
A
- start at the 4th energy level
- seven different orbitals so 14 electrons.
9
Q
subshell notation
A
1s2
1 = 1st shell
s = subshell
2 = number of electrons
