What is the electron configuration of fluorine?

Fluorine is the ninth element with a total of 9 electrons. In writing the electron configuration for fluorine the first two electrons will go in the 1s orbital. Since 1s can only hold two electrons the next 2 electrons for F go in the 2s orbital. read more

Fluorine's electron configuration in the ground state is 1s2 2s2 2p5. This means that the electrons in the fluorine atom are in their lowest possible energy state. These electrons are held in orbitals in each energy level. read more
