Answer 1) The group number of the most nonmetallic group that contains metalloids is Group VI A.
Explanation : Astatine (At) is the elemental metalloid which is found in group VI A which is placed in the bottom of most nonmetallic groups containing oxygen (O), sulfur (S), selenium (Se), tellurium (Te), and the radioactive element polonium (Po).
Answer 2) The group number of the most metallic group that contains metalloids is Group III A.
Explanation : Boron (B) is the metalloid which belongs to group III A which is the most metallic groups containing aluminum (Al), gallium (Ga), indium (In) and thallium (Tl). Amongst the placement in the top of metallic group Boron behaves like a metalloid.
Answer:
3) H-O
Explanation:
because oxygen and hydrogen have very high difference in electronegativity
Answer:
CO2
Explanation:
They share 2 electrons with carbon.
The elements can also be classified into the main-group elements (or representative elements) in the columns labeled 1, 2, and 13–18; the transition metals in the columns labeled 3–12; and inner transition metals in the two rows at the bottom of the table (the top-row elements are called lanthanides and the bottom-row ...
The reason is that the smaller ones make a high note depending on the size. The larger ones will make a deeper, lower notes.
