Water

What binds hold the elements together in a water molecule?

Hydrogen bonds hold together the atoms in a water molecule. A single water molecule is made up of two hydrogen atoms and one oxygen atom

Elements that make up a water molecule

The two elements that make up a molecule of water are hydrogen and oxygen; there are two hydrogen atoms and one oxygen atom, resulting in the chemical formula H2O. Hydrogen and oxygen bond together due to the number of electrons in their orbitals.

What does water hold

Thermal energy

Cohesion and Adhesion

They are nouns that describe a state of molecules sticking together. The difference between them is that adhesion refers to the clinging of unlike molecules and cohesion refers to the clinging of like molecules. Adhesion is the mutual attraction between unlike molecules that causes them to cling to one another.

Polarity of a water molecule

Water is a "polar" molecule, meaning that there is an uneven distribution of electron density. Water has a partial negative charge ( ) near the oxygen atom due the unshared pairs of electrons, and partial positive charges ( ) near the hydrogen atoms.

Nonpolar

a type of bond that occurs when two atoms share a pair of electrons with each other

Polar

a type of chemical bond where a pair of electrons is unequally shared between two atoms.

Solvent

able to dissolve other substances.

Universal Solvent

because more substances dissolve in water than in any other chemical. This has to do with the polarity of each water molecule. The hydrogen side of each water (H2O) molecule carries a slight positive electric charge, while the oxygen side carries a slight negative electric charge.

Hydrophilic

having a tendency to mix with, dissolve in, or be wetted by water.

Hydrophobic

tending to repel or fail to mix with water.

Capillary Action

the ability of a liquid to flow in narrow spaces without the assistance of, or even in opposition to, external forces like gravity.

What is hydrogen bonding?

the attractive force between the hydrogen attached to an electronegative atom of one molecule and an electronegative atom of a different molecule. Usually the electronegative atom is oxygen, nitrogen, or fluorine, which has a partial negative charge.

Solute

the minor component in a solution, dissolved in the solvent.

Surface Tension

the tension of the surface film of a liquid caused by the attraction of the particles in the surface layer by the bulk of the liquid, which tends to minimize surface area.
