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.

Explanation:

Atomic number 13 is aluminum (Al). It is in Group 13 (main group metal) of the periodic table, so it has 3 valence electrons. Metals in this group lose 3 electrons to form a +3 cation, and as a metal, it has ductile, malleable, and conductive properties. Option A is wrong because it's a metal, not non-metal, and forms +3 not -3 charge. Option B is wrong as it's not a metalloid, forms +3 not -5 charge, and is conductive. Option D is wrong because it's not a transition metal, has 3 valence electrons, and forms +3 not +1 charge.

Answer:

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