Question

all of the following statements about different elements are true except:
sulfur is considered a metalloid.
iodine is a halogen.
barium is an alkaline earth metal.
manganese is a transition metal.
krypton is one of the noble gases.

Explanation:

• Sulfur (\(S\)) is a non - metal, not a metalloid. Metalloids have properties intermediate between metals and non - metals. Common metalloids include boron (\(B\)), silicon (\(Si\)), germanium (\(Ge\)), arsenic (\(As\)), antimony (\(Sb\)), tellurium (\(Te\)), and polonium (\(Po\)).
• Iodine (\(I\)) is in group 17 of the periodic table, which are the halogens.
• Barium (\(Ba\)) is in group 2 of the periodic table, and group 2 elements are alkaline earth metals.
• Manganese (\(Mn\)) is in the d - block of the periodic table, so it is a transition metal.
• Krypton (\(Kr\)) is in group 18 of the periodic table, and group 18 elements are noble gases.

Answer:

Sulfur is considered a metalloid.
