Based on their locations on the periodic table, which best compares the properties of the metalloids arsenic (as) and antimony (sb)? arsenic has a more metallic behavior than antimony because arsenic’s atoms have fewer electron shells. arsenic has a more metallic behavior than antimony because arsenic’s atoms have more electron shells. arsenic has a more nonmetallic behavior than antimony because arsenic’s atoms have more electron shells. arsenic has a more nonmetallic behavior than antimony because arsenic’s atoms have fewer electron shells.

The answer is D because The correct option is this: ARSENIC HAS A MORE NON METALLIC BEHAVIOR THAN ANTIMONY BECAUSE ARSENIC ATOMS HAVE FEWER ELECTRON SHELLS.

Both arsenic and antimony are metalloids. Metalloids are chemical elements that has intermediate properties of those of metals and non metals. The properties of metals shown by metalloids are high melting point and conductivity while the properties of non metals shown by metalloids are brittleness and formation of acidic compounds. Metalloids can be found on group 13 to 16 of the periodic table. This means that they have between 3 and 6 electrons in their outermost shells and this makes it possible for them to either gain or lose electrons. 

The atomic number of arsenic is 33 while that of antimony is 51, this implies that, antimony has more electron shells than arsenic and this confers on it more metallic properties than that of arsenic.

the density of gold = 19.3 g/cm3

the relation between density and mass and volume is

density = mass / volume

given :

mass of gold = 13 g

density = 13g / volume = 19.3

volume = 13 /19.3 = 0.67 cm^3

thus volume of gold nugget = 0.67 cm^3
