Ions of the elements oxygen (o), sulfur (s), and selenium (se) usually have charges of 2-. ions of the elements fluorine (f), chlorine (cl), and bromine (br) usually have charges of 1-.

True

Explanation:

Hello,

As long as the group VIA elements have 6 valence electrons (electrons at the outermost shell) they just need two electrons to attain the octate, it means that the resulting charge must be -2. In such a way, since VIIA elements have 7 valence electrons, they just need one electron to attain the octate, it means that the resulting charge must be -1.

Best regards.

The Elements in the same group share certain properties, and each group has unique properties.
