How many bonding electrons are in water?
Two bonding electrons are in the molecule of H2O (light water)
What attractive force holds molecules of H2o together?
The attractive force is electrostatic, and described mathematically by Coulomb's Law. Because oxygen has a greater electronegativity than hydrogen, the electrons are shared unequally by these atoms, giving oxygen a negative charge and hydrogen a positive charge. And opposite charges attract.
How many bonding sites does beryllium have?
Beryllium has 2 bonding sites.

What forces between water molecules are responsible for many of water's unusual physical properties?
Hydrogen bonding between water molecules is responsible for many of water's unusual physical properties, such as high surface tension, cohesion, and adhesion. This bonding is a result of the attraction between the partially positive hydrogen atoms of one water molecule and the partially negative oxygen atom of another water molecule.
What does high incidence of hydrogen bonding mean?
It can mean high surface tension. Hydrogen bonding occurs in water because each water molecule contains 2 hydrogen atoms, and that constitutes the positive end of that molecule with no electron present (other than the one tied up in the covalent bond with oxygen.) The oxygen end of the molecule is negative (because of unshared electrons.) The attaction between the positive end of one water molecule to the negative end of another is hydrogen bonding, and it explains many of water's properties, including surface tension, how water expands when it freezes, and even why snowflakes are 6-sided.
How do an atom of hydrogen and a molecule of hydrogen differ?
A molecule consists of many atoms. When you have a hydrogen molecule, or whatever other type of molecule for that matter, you have many hydrogen atoms that make it.
Why do hydrogen bonds matter?
Hydrogen bonds are the strongest of the intermolecular forces that hold molecules together. They are important because the presence or absence of hydrogen bonds determines many physical and chemical characteristics of the compound in question. For example, a molecule with significant hydrogen bonding will have a much higher boiling point than one with no hydrogen bonding.
What type of bond does water polarity allow it to make?
Water polarity allows it to form hydrogen bonds. These bonds are formed between the slightly positive hydrogen atom of one water molecule and the slightly negative oxygen atom of another water molecule. The presence of hydrogen bonding gives water its unique properties, such as high surface tension and the ability to dissolve many substances.
In the molecule below how many atoms could make hydrogen bonds with water?
To determine how many atoms in a molecule can form hydrogen bonds with water, look for electronegative atoms that can either donate or accept hydrogen bonds, such as oxygen, nitrogen, or fluorine. Each of these atoms can form hydrogen bonds with the hydrogen atoms of water. If you provide the specific molecule in question, I can give a more precise answer regarding the number of atoms that could participate in hydrogen bonding with water.
