Definitions
New substances formed as a result of a chemical change
Products
The notation indicating elements in a compound and the ratios of the atoms of each element.
Chemical formula.
Surface tension is a result of this force.
Cohesion
What substances can non-polar substances dissolve?
Only other non-polar substances.
(Ionic and Polar substances can dissolve each other.)
Substances that undergo a chemical change.
Reactants
Numbers that appear before a formula in a chemical equation to show how many atoms or molecules of each reactant or product are involved in the reaction.
Coefficient.
A chemical bond in which two atoms share one or more pairs of valence electrons.
Covalent bond
When atoms lose electrons they become this.
Positive Ions or Cations.
A molecule that has slight positive and negative charges due to an imbalance in the way electrons are shared.
Polar Molecule
Numbers in a chemical equation which show the number of atoms of an element in a molecule or compound.
Subscripts
A chemical bond formed between oppositely charged ions.
Ionic Bond
In a water molecule, which atom has the greater attraction for elelctrons.
Oxygen.
This make water molecules polar, because the shared electrons spend more time around the Oxygen than the Hydrogen. giving the Oxygen a partial negative charge and the Hydrogen a partial positive charge.
Electrons that are in the highest energy level of an atom.
Valence electrons
Butane, which contains 8 atoms of Carbon and 18 atoms of Hydrogen, has this chemical equation.
C8H18
The force of attraction between molecules of different substances so that they tend to stick together.
Adhesion.
This property allows water to dissolve many substances.
Its polarity.
A region of space around the nucleus where electrons are most likely to be found.
Orbitals
An electron configuration in which the highest occupied energy level is filled with electrons is called this.
Stable.
The force of attraction between molecules of the same substance so that they tend to stay together.
Cohesion
What is happening to electrons in the outer orbital that causes a chemical bond?
The orbital is not full, so they either give up or take on an electron.
