Answer 1

The different sublevels on the periodic table are represented by the s, p, d, and f orbitals. Each sublevel can hold a specific number of electrons. The sublevels fill up in a specific order based on the energy levels of the orbitals.

Step-by-step explanation:

The different sublevels on the periodic table are represented by the s, p, d, and f orbitals. The s sublevel has one orbital, the p sublevel has three orbitals, the d sublevel has five orbitals, and the f sublevel has seven orbitals. Each orbital can hold 2 electrons, so the s sublevel holds 2 electrons, the p sublevel holds 6 electrons, the d sublevel holds 10 electrons, and the f sublevel holds 14 electrons.

The sublevels fill up in a specific order based on the energy levels of the orbitals. The order of filling is as follows: 1s, 2s, 2p, 3s, 3p, 4s, 3d, 4p, 5s, 4d, 5p, 6s, 4f, 5d, 6p, 7s, 5f, 6d, 7p. This order ensures that the lower energy orbitals are filled before the higher energy ones.
