Electron Configuration and Sublevels

These flashcards cover key concepts from the lecture notes on electron configurations, sublevels, and the order of filling orbitals.

What is the maximum number of electrons that can be held in an s sublevel?

2 electrons

What is the order of filling for the electron sublevels?

1s, 2s, 2p, 3s, 3p, 4s, 3d, 4p, 5s, 4d, 5p, 6s.

What is the maximum number of electrons in a p sublevel?

6 electrons

How many electrons can a d sublevel hold at maximum?

10 electrons

What is the formula to calculate the maximum number of electrons for any principal energy level (PEL)?

2n², where n is the principal energy level.

Which sublevels contain 5 orbitals?

The d sublevel contains 5 orbitals.

Which sublevels can be found in the third principal energy level (PEL)?

s, p, and d sublevels.

In which order do the sublevels increase in energy?

s < p < d < f.

What is the maximum number of electrons in an f sublevel?

14 electrons.

What must you do before filling higher energy sublevels?

Completely fill the lower energy sublevels first.
