A nonpolar bond could only occur with covalent bonds, as all ionic bonds are polar. This means that all elements involved in nonpolar bonds are nonmetals.
Boron is in group 3 and forms generally 3 covalent bonds. Because forming 3 bonds only gives boron a share of 6 electrons boron compounds are Lewis acids.

Hydrogen, depending upon what element it is combining with, can act either as a metal or a nonmetal. But as a nonmetal it shares electrons in the form of covalent bonds, rather than actually donating them. Similarly, carbon can react with metals or nonmetals but forms covalent bonds. To truly donate or accept electrons is to form ionic bonds, and no element has the flexibility to form ionic bonds both as a donor and as an acceptor. Elements can do one or the other, if they form ionic bonds. Some elements only form covalent bonds.
Only one covalent bond.
yes.
The only group of neutral elements is the noble gases. They are in group 0. They are electronically stable elements that do not tend to react. They exist as single molecules.
Only halogens and members of the oxygen group can form diatomic molecules joined by a single covalent bond.
Elements don't have bonds, only compounds do.
hydrogen, oxygen, fluorine, bromine, iodine, nitrogen, and chlorine are all nonmetals. nonmetals form covalent bonds.
Only nonmetals can form covalent bonds. Mainly because in a covalent bond the atoms are sharing electrons, as in an ionic bond the two atoms are taking electrons.
Hydrogen is not considered a key part in any covalent bond. There are many covalent bonds that don't include hydrogen (C-O, N-O, N-C, etc.) Though Hydrogen is in group 1 with metals that do not form covalent bonds, Hydrogen itself does form covalent bonds. Hydrogen is the oddball in the periodic table and appears in group 1 because of the fact that it has only 1 valence electron, like the other elements in that group.
A nonpolar bond could only occur with covalent bonds, as all ionic bonds are polar. This means that all elements involved in nonpolar bonds are nonmetals.
Only oxygen. The halogens and hydrogen form single covalent bonds, and nitrogen forms a triple covalent bond.
Boron is in group 3 and forms generally 3 covalent bonds. Because forming 3 bonds only gives boron a share of 6 electrons boron compounds are Lewis acids.
All elements which have distinct multiatomic molecules are covalent. (Noble gases have only one atom per molecule, so no bonds; metals are ... metallic.) If they were ionic, how would the iodine atoms "know" which ones were supposed to be positive and which ones were supposed to be negative?
Since it is composed of one element it can only have covalent bonds.
