is the physical science that deals with the composition, structure, and properties of substances and also the transformations that these substances undergo.
is the scientific study of the properties and behavior of matter. It is a physical science within the natural sciences that studies the chemical elements that make up matter and compounds

Branches of Chemistry
Organic Chemistry
Inorganic Chemistry
Analytical Chemistry
Physical Chemistry
Mostly concerned with the study of chemicals containing the element carbon
the study of the structure, properties, composition, reactions, and preparation of carbon-containing compounds?
Organic chemistry
the study of all elements of compounds other than organic compounds
the study of the synthesis, reactions, structures, and properties of compounds of the elements
Inorganic Chemistry
The study of qualitative and quantitative analysis of elements and compounds
the science of obtaining, processing, and communicating information about the composition and structure of matter
Analytical Chemistry
The study of reaction rates, mechanisms, bonding and structure
deals with the principles of physics involved in chemical interactions
in terms of the principles, practices, and concepts of physics such as motion, energy, force, time
Physical Chemistry
Is the positively charged particle
Proton
Negatively charged particle
Electron
No change ( neutral particle )
Neutron
Refers to the sum of the number of protons and neutrons
Atomic Mass
A pure substance that cannot be decomposed into simpler substances; made up of only one kind of atom
Example: Gold, copper, iron, hydrogen, oxygen
Element
the process by which heat or electricity is directly transmitted through a substance
Conduction
the process by which sound waves travel through a medium.
Conduction
Heat transfer through solids
Conduction
Heat transfers through liquid or moist air
Convection
the process of heat transfer by the bulk movement of molecules within fluids such as gases and liquids.
Convection
Heat transfers through dry air or a vacuum / empty space
Radiation
is energy that comes from a source and travels through space at the speed of light.
Radiation
