The electron configuration of vanadium is [Ar.] 3d3.4s2; the "Ar." refers to the electrons of argon, and the additional notations describe further electrons. There are 2 electrons in the first shell, 8 electrons in the second, 11 electrons in the third and 2 electrons in the fourth shell.
Like many elements, vanadium was discovered more than once. The first discovery was by Andres Manuel del Rio in Mexico in 1801. The second discovery was by Nils Sefstrom in 1831. It was named after a Germanic goddess of beauty.
Vanadium is a hard metal with a high melting point. It's often alloyed with other metals to make gears, springs, castings and forgings.
