Contains a blend of 2 or more kinds of matter each of which retains it's own identity and properties

A logical approach to solving problems

Name given to any of isotope of an element

Distance between corresponding points on adjacent waves

Is credited with developing the first successful periodic table

The study of the composition, structure, and properties of matter and the changes and it undergoes

Any digit in a measurement that is known plus one final digit, which is uncertain or estimated

6.02 x 1023 parts or atoms in 1 mole of substance

States that an electron occupies the lowest energy orbital that can receive it

Contains element's name, atomic mass and properties

The state of matter in which a material has neither a definite shape nor a definite volume

Written in the form M x 10n where M is a number greater than or equal to 1 but less than 10

Mass is neither created nor destroyed during ordinary chemical or physical change.

3 orientations (x, y, and z)

The principle that states that the physical and chemical properties of the elements are periodic functions of their atomic numbers

Organic, Inorganic, Physical, Analytical, Biochemistry, and Theoretical

Calculated by subtracting the exponential value from accept. value, divide by the accept., and x 100

Fired positively charged particles at metal foil and concluded that most of the mass of an atom was concentrated in the nucleus

States that orbitals of equal energy are occupied by one electron before any orbital is occupied by a second electron, and all electrons in singly occupied orbitals must have the same spin

Contains nearly all of the atom's mass
Contains nearly all of the atom's volume

States that it is impossible to determine simultaneously both the position and velocity of an electron

Mendeleev predicted that the spaces in his periodic table represented
