how many electrons does hydrogen have in its valence shell when it is full? (1 point)\none\nseven\neight\ntwo

Answer:

one, seven, eight, two

Brief Explanations:

Hydrogen has one electron in its valence shell when it is full. Hydrogen is in the first energy level (n = 1). The first energy level can hold a maximum of 2 electrons, but hydrogen only needs 2 electrons to fill its valence shell. However, this is a special case as hydrogen follows the duet rule. The options provided in the question are one, seven, eight, two. But the correct answer is two. There might be a mis - understanding in the options. Hydrogen's valence shell (n = 1) has a maximum capacity of 2 electrons. When it is full (as in H₂, for example), it has 2 electrons in its valence shell.
