Question

You can find the number of valence electrons by identifying which period it is in.
true
false

Answer 1

False. The number of valence electrons is primarily determined by the group (or family) of the element on the periodic table, not the period. Elements in the same group have the same number of valence electrons, regardless of their period. For example, all elements in Group 1 have one valence electron, while those in Group 2 have two, and so on. The period indicates the number of electron shells, not the number of valence electrons.
