What is fluorine and how many electrons does it have?

What is fluorine?

Fluorine is a chemical element with the symbol F and atomic number 9. It is a noble gas and a halogen, which means it is a reactive and highly reactive element. Fluorine is the most reactive of the known elements and is the only element that can form covalent bonds with hydrogen.

How many electrons does fluorine have?

Fluorine has 9 electrons. These electrons are distributed in two energy levels. The first energy level contains two electrons, while the second energy level contains seven electrons.

These electrons are distributed in three orbitals, two s orbitals and one p orbital. This distribution of electrons gives fluorine an electron configuration of 2-7. This electronic configuration is what allows fluorine to form covalent bonds with other elements.
