Question

How many electrons does hydrogen have in its valence shell when it is full?(1 point)
seven
eight
two
one

Answer 1

Hydrogen has one electron in its valence shell. When it is involved in bonding or achieving a stable configuration, it can share or gain another electron to fill its shell, achieving a full valence shell similar to the noble gases (which is two electrons, as hydrogen follows the duet rule). However, it doesn't have seven, eight, or two electrons when it is full; thus, the answer to the given options is "one".
