1 Explain the meaning of various chemical formulas (empirical, molecular, and structural formulas). 2  Calculate weight and mole percentages from a formula.  Derive chemical formulas from a given set of information.
A: Zinc belongs to the family of elements found in Group 12. Some other elements in this family are cadmium and mercury. These three elements are metals, but mercury is a metal that is liquid at room temperature, while zinc and cadmium are solids at room temperature.
An element's main group number indicates how many valence electrons each atom of that element will have, and because sulfur is part of group six on the periodic table, this indicates that this element has six electrons in its outermost electron shell..
