Key Concepts
Group 16 elements are: naturally occurring oxygen, sulfur, selenium, tellurium, polonium, and the man-made element livermorium.
The atoms of Group 16 elements have 6 valence electrons.
An atom of hydrogen has 1 valence electron.
Bonds between hydrogen and Group 16 atoms are covalent so the hydrides of Group 16 elements are covalent molecules.
Group 16 hydride molecules have a bent shape.
The most significant intermolecular force acting between water (H2O) molecules is the hydrogen bond.
Weaker intermolecular forces act between other Group 16 hydride molecules.
The melting point and boiling point of water (H2O) molecules is unexpectedly high due to the stronger hydrogen bonds acting between water molecules.
Structure of Group 16 Hydrides
Consider the structure of a hydrogen, H, atom.
Hydrogen has atomic number, Z, 1 so it has only one positively charged proton in the nucleus of the aotm.
A neutral hydrogen atom must therefore have just one negatively charged electron occupying the space around the nucleus in order for the charge to be balanced.
The Lewis Structure (electron dot diagram) for an atom of hydrogen is shown on the right.H
An atom of hydrogen can achieve the stable electron configuration of helium, He, by contributing its 1 electron to be shared between itself and another atom, such as an atom of a Group 16 element.
So, let's consider the structure of each Group 16 element:

Number (Z)NameSymbolNo. Valence ElectronsTrends8oxygenO6Atomic number (Z), the number of protons in the nucleus of the atom and therefore the number of electrons present in an atom of the element, increases down the group from oxygen (O) to livermorium (Lv).
The number of valence electrons, the number of electrons in the highest energy level, remains constant at 6 for the atoms of Group 16 elements.

Due to the H-Bonding with other molecules of hydrogens in hydride compound.
