1. a. Principal quantum number (energy level)
b. Subshell/orbital type
c. Number of electrons in the subshell
2. Same: Both are s and p orbitals with the same shape types (s spherical, p dumbbell) and follow the same Aufbau principle rules.
Differ: 2s is lower in energy than 2p; 2s penetrates closer to the nucleus; 2s has no angular nodes while 2p has one.
3. 3d
4. 14
5. 5
6. i. E
ii. A
iii. E
iv. D
Lewis dot diagram: Xe with 8 dots (2 on each side)
v. B
vi. A = Cs, B = I, C = Sn, D = Xe, E = Al
