Vanadium has five valence electrons. Valence electrons are the electrons that an element gives up or gains during a chemical bond with another element. Vanadium can be found five elements in from the left on the periodic table, which is a way of showing that it has five valence electrons.
Vanadium was discovered in Mexico in 1801 by Andres Manuel del Rio and again in 1831 by Nils Sefström. Its name comes from the Scandinavian goddess of beauty, Vanadis. Vanadium is a silver-gray metal. The abbreviated electron configuration for vanadium is [Ar] 3d3 4s2. The abbreviated electron configuration shows where an element's valence electrons are located; for vanadium, it is on the 4s sub-shell (2) and the 3d sub-shell (3).Learn More
Beryllium has two valence electrons. Valence electrons are those electrons that are capable of participating in the formation of chemical bonds with other atoms. These chemical bonds occur through the sharing of these two electrons with other atoms.Full Answer >

Molybdenum has six valence electrons. The atomic number of molybdenum is 42, and its electron configuration is 1s22s22p63s23p63d104s24p64d55s1 or 2, 8, 18, 13, 1 electrons per shell. The electrons in the 4d55s1 constitute its valence electrons.Full Answer >
Chromium has six valence electrons. The atomic number of chromium is 24, and its electron configuration is 1s22s2 2p63s23p63d54s1 or 2, 8, 13, 1 electrons per shell. The electrons in the 3d54s1 shells form the valence electrons as the five electrons in the 3d shell participate in chemical bond formation.Full Answer >
