What part of this orbital diagram for Nitrogen is INCORRECT?
↑ ↓ ↑ ↓ ↑ ↓ ↑
__ ___ ___ ___ ___
1s 2s 2p
the arrows in 2p should not be paired, it should be 3 up arrows each in their own spot
What word describes the tendency of an atom to attract electrons?
Electronegativity

What is the electron configuration for Mg+2 ion?
1s2 2s2 2p6
What is the name of "The Bus Rule" that states one electron must be in each orbital of a sublevel before they are paired.
Hund's Rule
Which of the following would have this electron configuration:
1s22s22p63s23p6
Ne, Cl-1, S, K-1
Cl-1
When comparing Iron and Zinc, which element has a weaker effective nuclear charge?
Iron because it has less protons
Order these from smallest to largest atomic radius:
H, K, Li, Na
H < Li < Na < K
What is the complete electron configuration for Magnesium?
Complete the orbital diagram for Lithium.
_____ ______
1s 2s
↑ ↓ ↑
1s 2s
What element has this electron configuration:
1s22s22p63s23p64s23d5
Mn
WHAT causes atomic radius to DECREASE from left to right in a period.
more protons = stronger nuclear charge = pulls electrons in closer making the atom smaller
Order these by electronegativity from least to greatest:
Cl, P, S, Ar
Ar < P < S < Cl

[Ar] 4s23d3
Complete the orbital diagram for Carbon
____ ____ _____ ______ ______
1s 2s 2p
↑ ↓ ↑ ↓ ↑ ↑ ______
1s 2s 2p
Which would have a smaller atomic radius, K or K+1?
K+1 because it would lose its 3rd energy level making it have only 2 energy levels where as K has 3 energy levels
