branches and periodic table stuffs

Chemistry

Study of Matter and how it interacts with energy

Organic chemistry

the study of carbon containing compounds

inorganic chemistry

study of non-organic things (not actually a branch but a starting point for many degrees, etc)

physical chemistry

properties and changes of matter and relationships with energy

analytical chemistry

identifying components and compositions of substances

biochemistry

substances and processes in living things

theoretical chemistry

math, computers, and predictions

metalloids

found on the staircase

metals

located on the left side of the periodic table

noble gases

full valence shell, found as single atoms (monoatomic), and are colorless/tasteless/odorless/non flammable and are located in the far right column on the periodic table

nonmetals

located on the upper right side of the periodic table, and also hydrogen

fact

basic statement established by experiment or observation (true under those conditions)

hypothesis

tentative educated prediction or guess about what will happen in an experiment

theory

a widely accepted explanation for why something happens in the realm of science. supported by much and many, but can change if something is discovered that it cannot explain

law

explain what happens as opposed to why it does (often an equation for an observed pattern)

pure substance

elements (1+ of the same atom) and compounds- chemically bonded together

homogenous mixture

elements and/or compounds that are only physically mixed, but so uniformly so that it still appears uniform under the microscope

heterogenous mixture

either by eye or microscope, is not uniformly mixed
