The Structure of Matter Landon Hodge Flashcards
Chemical structure
The order of atoms in a certain substance
Chemical bond
Force that keeps atoms or ions from separating
Bond length
Average space between two bonded atoms nuclei
Bond angle
Angle made from two bonds attached to the same atom
Ionic bond
Bond made because of the attraction between two ions with opposite charge
Metallic bond
Bond made by attraction between two metal ions with a positive charge and electrons around them
Hydrogen bond
When an oxygen atom of a water molecule is attracted to the hydrogen atom of a nearby water molecule
Covalent bond
Bond made when atoms share electrons
Polyatomic ion
An ion formed of two covalently bonded atoms
Formula unit
Formula for the compound of two ions
Non polar covalent bond
Bond where electrons are shared equally
Polar covalent bond
Bond where electrons are not shared equally
Empirical formula
Composition of compound in relative numbers and types of atoms in most reduced ratio
Molecular formula
Chemical formula which shows numbers of atoms and the kind in a certain molecule but not how the atoms are arranged
Organic compound
Compound that is covalently bonded with carbon in it
Polymer
Big molecule made with five or more small units
Carbohydrate
Compound with carbon hydrogen and oxygen which provides nutrient
Protein
Compound made of chains of amino acids that is a key part of cells
Amino acid
An organic molecule with a carboxyl and amino group which combine to make proteins
Hydrocarbon
Compound made of only hydrogen and carbon atoms
Alkane
Hydrocarbons with single covalent bonds
Alkene
Hydrocarbons with one or more covalent bond between carbon atoms
DNA
Complex structure which determines genetics
