What is a chemical structure?
A chemical structure is the arrangement of atoms in the molecule.
What is a chemical bond?
A chemical bond is the attractive force that holds atoms together.
What is a bond length?
Bond length is the distance between the nuclei of two bonded atoms.
What is a bind angle?
A bond angel is the angle formed by two bonds to the same atom.
What is a hydrogen bond?
Hydrogen bond is one oxygen atom attracted to two hydrogen atoms.
What is an ionic bond?
An ionic bond is a bond formed by the attraction of two different charged ions.
What is a formula unit?
A formula unit is the formula of the molecule.
What is a metallic bond?
A metallic bond is a bond formed by the attraction between positively charged metal ions and electrons.
What is a covalent bond?
A covalent bond is a bond formed when atoms share more or one pairs of electrons.
What is a nonpolar covalent vond?
A nonpolar covalent bond is a bond when electrons are shared equally.
What is a polar covalent bond?
A polar covalent bond is when the shared electrons are attracted to the nucleus of one atom more then the other.
What is a polyatomic ion?
A polyatomic ion is an ion made of two or more atoms.
What is a empirical formula?
A empirical formula is the composition of a compound in terms of the relative numbers and kinds of atoms in the simplest ratio.
What is a molecular formula?
A molecular formula is a chemical formula that shoes the number and kinds of atoms in a molecule, but not the arrangement of the atoms.
What is an organic compound?
An organic compound is a covalently bonded compound that contains carbon.
What is polymer?
Polymer is a large molecule that is formed by more than five monomers.
What is a carbohydrate?
A carbohydrate is any organic compound that is made of carbon, hydrogen, and oxygen and that provides nutrients to the cells of living things.
What is protein?
Protein is an organic compound that is made of one or more chains of amino acids and that is a principal component of all cells.
What is amino acid?
Amino acid is any one if 20 different organic molecules that could contain a carboxyl and an amino group and that combine to form protein.
What is a hydrocarbon?
A hydrocarbon is a compound that is made of only carbon and hydrogen.
What is alkanes?
Alkanes are hydrocarbons that have only single covalent bonds.
What are alkene?
Alkene are also hydrocarbons. Alkene are different from alkanes because they have at least one double covalent bond between carbon atoms.
What is DNA?
DNA is a polymer with a complex structure.
