Elements of Life: Electronic Structure Flashcards
What is another name for electron shells
Energy levels
What do electron shells contain
Sub shells
How many sub levels are there in the 1st shell
1
How many sub levels are there in the 2nd shell
2
How many sub levels are there in the 3rd shell
3
How many sub levels are there in the 4th shell
4
What is the order of subshells ( letters )
s, p, d, f,
Number of orbitals in subshell s
1
Number of orbitals in subshell p
3
Number of orbitals in subshell d
5
How many electrons can each orbital hold
2 electrons with opposite spins
Max no. electrons for s subshell
2
Max no. electrons for p subshell
6
Max no. electrons for d subshell

Explain Hunds Rule ( terms of how electrons fill orbitals )
Bus seat theory = rather sit alone if seats free than in a pair
= electrons prefer to occupy orbitals on there own = only pair up when no empty orbitals of the same energy available
In ions what electrons are lost first
Electrons in the highest energy levels
What is special about transition metals
Loose 4s electrons before 3d when forming ions
Important rule to remember about 4s and 3d
4s = power energy then 3d = 4s orbital filled before 3d orbitals
What is the short hand way of representing electronic configuration
Replace sublevels before hand with the noble gas just before the atom
Learn sub shell blocks on periodic table
Look at periodic table
How do you draw shape of an s orbital
As a circle
How do you draw shape of p orbital
