Covalent nature of the bond
They are between two atoms.These atoms have high electro negativity difference
Electronegativity decreases down the group. Metallic character increases.
The electronegativity can be defined as the tendency of an atom to attract an electron.There are three rules of Bonding:-Metallic elements form metallic bonded solids and metal: Metal combinations form metallically bonded solids.Nonmetallic elements and non-metal : Non-metal combinations are covalently bonded. A bond between two non-metal atoms is Covalent.Bonds between metals and nonmetals are either ionic or covalent, depending on the electro-negativity difference.The third rule is governed by critical electro-negativity difference from Pauling's expression for the ionicity fraction of a bond.For more insight on Electro-negativity difference you can search Pauling's Scale or study the related link below.
Electro negativity difference is zero.So it is non polar.No it is non polar.It contains same atoms and no e.negativity difference.
Yes they form H bonds.They have enough electro negativity difference
They are between two atoms.These atoms have high electro negativity difference
The element with the highest electro negativity is Fluorine. The general trend on the periodic table for electro negativity is that as you go across periods (horizontally) the electro negativity increases while going down groups (vertically) the electro negativity decreases.
The electro-negativity of elements increases as you move across a period.
There should be much electro negativity difference to form H bond.There is no enough difference between H and S.
Electro negativity difference is zero.So dipole moment is zero.

Francuim is thought to have the lowest electro-negativity.Linus Pauling estimated that francium had the same electro-negativity as Caesium = 0.7. The electro-negativity of caesium was later revised to 7.9 but francium is so unstable and reactive that it is not possible to obtain samples of pure francium to accurately determine its electro-negativity.
Yes Because the electro-negativity number of N is 3.0 - the electro-negativity number of H is 2.1 =.09 If two elements have an electro-negativity number between 0.5 and 2.1, it has a polar bond. Another way is that N and H are both non-metal and they have an unequal share of electron so it is a polar covalent bond.
