The electron configuration of sulfur is [Ne) 3s2.3p4.
The electron configuration provided seems to be incorrect. The correct electron configuration for an element is based on the Aufbau principle, which governs the way electrons fill energy levels and sublevels. Double-check the electron configuration using the correct order of filling for orbitals.
The element with that electron configuration is Iron.
The electron configuration for an atom of fluorine is [He]2s2.2p5.

an element with 2 valence electrons can obtain a stable electron configuration by "kicking out" two electrons to have the same electron config as the noble gas in the previous period
The electron configuration is the number of electrons in each energy level of an element. The electron configuration of Li is, 1s2 2s1. The electron configuration of F is, 1s2 2s2 2p5.
