What is Chemistry/Basics
small particles that make up matter
microscopic
Contains carbon
a compound always contains the same elements in the same proportion by mass
Law of Definite Proportions
Positively charged
Proton
Makes up nucleus
Protons and Neutrons
study of composition of matter and the changes it undergoes
Chemistry
matter without carbon
Inorganic Chemistry
same two elements can be in multiple compounds, but they must combine in different ratios which are simple whole numbers
Law of Multiple Proportions
Negatively charged
Weight of 1
Proton and Neutron
can be seen, touched, and measured
Macroscopic
behavior and changes to matter related to energy change and reactions
Psychical Chemistry
during a chemical reaction the mass of reactants=Mass of products
Neutral
Neutron
No weight
Electron
directed towards a specific goal
Applied Chemistry
components and composition, food, nutrients, quality control
Analytical Chemistry
Important scientist that helped discover most about atoms
Daltons Atomic Theory
Number of protons
Atomic number
same Atomic number with different neutrons
Isotopes
greater understanding of the theories behind how matter is changing
Pure Chemistry
matter and processes of living organisms, metabolism, fermention
Biochemsitry
Gold foil experiment
Ernest Rutherford
total protons + neutrons
Mass number
weighted average of all the isotopes of an element
Atomic Mass
