Penetration Order of Orbitals

### Formula:

$$s>p>d>f$$

### Terminologies:

- Penetration β†’ Ability of an electron to come close to the nucleus.

- s, p, d, f β†’ Types of atomic orbitals.

### Usage:

- Used to compare electron density near nucleus.

Question 1

The $$2s$$ and the $$2p$$ orbital energies of hydrogen atom are $$E_{2s}(\mathrm{H})$$ and $$E_{2p}(\mathrm{H})$$, respectively. The $$2s$$ and the $$2p$$ orbital energies of lithium atom are $$E_{2s}(\mathrm{Li})$$ and $$E_{2p}(\mathrm{Li})$$, respectively. The correct option(s) about the orbital energies is(are)
