Hydrogen's Dual Periodic-Table Position
This video presents the same text shown beside it, spoken and on screen. It adds nothing the text does not say.
State
Hydrogen fits group 1, losing one electron to form H+, or group 17, gaining one to form H−, since its single electron half-fills its shell.
Show
Hydrogen forms HCl by sharing an electron pair, like a nonmetal, yet forms H+ in acids, like a metal.
Watch for
Neither placement is fully correct alone — treating hydrogen as typical of either group misses its special status.
