Answer 5

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.

Answer 6

its alluminum so what is alluminum

Answer 7

Pure aluminium is a silvery-white metal with many desirable characteristics. It is light, nontoxic (as the metal), nonmagnetic and nonsparking. It is somewhat decorative. It is easily formed, machined, and cast. Pure aluminium is soft and lacks strength, but alloys with small amounts of copper, magnesium, silicon, manganese, and other elements have very useful properties. Aluminium is an abundant element in the earth's crust, but it is not found free in nature. The Bayer process is used to refine aluminium from bauxite, an aluminium ore.

Name: aluminium
Symbol: Al
Atomic number: 13
Relative atomic mass (Ar): 26.9815386 (8)
Standard state: solid at 298 K
