Verified step by step guidance1
Identify the element in question, which is hydrogen (H).
Recall that valence electrons are the electrons in the outermost shell of an atom that participate in chemical bonding.
Determine the electron configuration of hydrogen. Hydrogen has only one electron, which occupies the first energy level (1s orbital).
Since the first energy level can hold up to 2 electrons and hydrogen has 1 electron in this shell, all of hydrogen's electrons are valence electrons.
Conclude that hydrogen has 1 valence electron.
