Question

Elaborate on what can be learned about the properties by the location of element on the periodic table. Use atomic number 13 as an example. A) It is a non-metal, has 3 valence electrons, becomes a cation with a -3 charge, and is brittle, moldable, and non-conductive. B) It is a metalloid, has 3 valence electrons, becomes a cation with a -5 charge, and is workable, inelastic, and non-conductive. C) It is a main group metal, has 3 valence electrons, becomes a cation with a +3 charge, and is ductile, malleable, and conductive. D) It is a transition metal, has 1 valence electrons, becomes a cation with a +1 charge, and is ductile, malleable, and conductive. Eliminate

Answer 1

C. It is a main group metal, has 3 valence electrons, becomes a cation with a +3 charge, and is ductile, malleable, and conductive.

Explanation:It is a main group metal, has 3 valence electrons, becomes a cation with a +3 charge, and is ductile, malleable, and conductive.

The location of element on the periodic table gives the electron configuration. From this you know the number of valence electrons, type of ion formed (cation or anion), and the charge of the ion. Additionally the location gives info about the properties because you know if the element is a metal, nonmetal, or metalloid. Using atomic number 13 as an example - Aluminum is a main group metal, has 3 valence electrons, becomes a cation with a +3 charge, and is ductile, malleable, and conductive.
