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.
