Question

similar to the previous picture, here is how will fill the electrons in orbitals. hydrogen 1s^1 carbon 1s^2 2s^2 2p^2 oxygen 1s^2 2s^2 2p^4 sodium 1s^2 2s^2 2p^6 3s^1 aluminum 1s^2 2s^2 2p^6 3s^2 3p^1 phosphorus 1s^2 2s^2 2p^6 3s^2 3p^3 6. match up what you think each of these symbols mean: 1s^2 2s^2 2p^4 1. 2. 3. 4. 5. a) manager’s code b) a single orbital (place where electrons are likely found) c) 2 electrons with opposite spins d) a single electron e) a sublevel (orbitals with equal energy)

Explanation:

1. The notation like $1s^{2}2s^{2}2p^{4}$ represents the electron - configuration of an atom, which is related to the sublevels where electrons are located. So it corresponds to a sublevel (orbitals with equal energy).
2. A single box represents a single orbital where electrons are likely found.
3. Three connected boxes represent a set of orbitals within a sublevel (e.g., the three $p$ - orbitals in a $p$ sublevel).
4. Two arrows in opposite directions in a box represent 2 electrons with opposite spins.
5. A single arrow represents a single electron.

Answer:

1. E
2. B
3. E
4. C
5. D
