Electron Configuration of Fluorine

Fluorine (F), atomic number 9, follows Pauli's exclusion principle:
- A maximum of 2 electrons with opposite spins can occupy each orbital.

Covalent Bonds

One characteristic of covalent bonds is the sharing of electrons between atoms.

Sublevel with One Orbital

The 's' sublevel contains one orbital.

Lewis Structure Element Identification

Information from Electron Distribution

The given electron distribution shows an element located in Group IVA, Period 4 (not calcium).
It is a representative element.
Electron distribution identifies that it's not calcium.

Type of Chemical Bond (N and O)

Nitrogen (N) and oxygen (O) form a covalent bond.

Sulfur Electron Configuration

The electron configuration of sulfur (S) is 1s², 2s², 2p⁶, 3s², 3p⁴.

Ionic Compound Formation

Calcium and oxygen, potassium and bromine are more likely to form ionic compounds than the other pairs.

Element with Electron Distribution

The element with the given electron distribution is phosphorus (P), containing 5 valence electrons. It's located in period 3.

Octet Rule

The octet rule states that atoms tend to gain, lose, or share electrons to achieve a full outer electron shell (8 valence electrons).

Pauli Exclusion Principle

The Pauli Exclusion Principle states that no two electrons in an atom can have the same four quantum numbers. Electrons must fill orbitals individually before pairing up.
