Question:
Which of the following groups of elements contains the most valence electrons?
(a) Halogens
(b) Chalcogens
(c) Noble gases
(d) Alkali metals
Valence Electrons:
Valence electrons are electrons in the outermost shell of an atom. Generally, those are the electrons that the atom can use to make covalent bonds or ionic bonds. A quick way to tell the valence electrons is by the group number i.e. the columns in a periodic table.
