A chemical substance formed by the union of two or more atoms.
The same or different is equal to what term?
Compound
What is the smallest particle of a compound, That has all of the compounds properties??
A Molecule
Exsplain Isotopes
Isotopes are the same element properties within an atom however they have a different number of nuetrons.
Radioactive Isotopes are created though what process?
Decaying which occurs when the outermost ring has an unstable amount of electrons
What are the 3 three types of chemical bonds?
Ionic
Covalent Polar and Non Polar
Hydrogen Bonds
What is a Cation
Positively charged particles through the loss of an electron
What is an anion
Negatively charged particles that become negative through gaining a electron
When bonding occurs within atoms and they become compounds The elements that make up this compound are now called?
Cations And anions because
1) To form the bond they needed a positive and negative charge
2)Cation is the positive charge for one of the two elements
3)anion is the negative charged element
WHAT IS DEHYDRATION SYNTHESIS?
When two molecules unite by losing water
What is hydrolisys
When a Molecule is broken and water is added
What is oxidation
A Reaction in which an atom or molecule loses an electron
What is reduction
A reaction in which a molecule or atom gains an electron
What is anabolic
Chemical reaction in whichlarge molecules are made from smaller ones
What is catabolic
Chemical reaction which large molecules are broken into smaller ones
Exothermic
Energy is released as chemical bonds are formed or broken
Endothermic
Energy must be supplied in order to form or break bonds
Inorganic Compounds
All of these lack Carbon.
Relatively small in number 100 of thousands
Salts
All of these are ionic, All are soluble in water,
They conduct electricity because they disassociate
What is called the universal solvent?
Water

What are positively formed particles that have lost an electron
Cation
What are negatively charged particles because they have gained an electron
Anion
What are triglycerides
Simplest form of Lipids which are fats
Triglycerides are formed by?
Dehydration synthesis?
What makes isotopes radioactive?
Decaying over a period time because of it instability
Define Chemical Reactions?
Chemical reactions are an attempt by an atom to form an out most complete orbit and become stable and unreactive.
Define Compound?
A chemical substance formed by the union of two or more atoms (same or different atoms)
Define Molecule?
The smallest particle of a compound that has all of the properties of the compound
3 types of chemical bonds?
Ionic
Covalent (polar-nonpolar)
Hydrogen
Define Ionic Bonds?
One atom gives electrons to another atom
Define Covalent Bonds?
Formed by the sharing of electrons
What happens when covalent bonds are broken?
Energy is released
List chemical bonds from strongest to weakest?
Covalent, Ionic, Hydrogen
What is a common occurance from intermolecular attractions
+ & - regions attracted to themselves causes them to fold and bend
Define Exothermic?
Energy is realesed as chemical bonds are formed or broken
Define Reduction?
Energy must be supplied in order to form or break bonds = eating
Difference between Inorganic and Organic compounds?
Carbon (is in all Organic Compounds)
