chapter 5 Alyssa Flashcards
Chemical structure
Arrangement of atoms in a substance
Chemical Bond
Force that holds atoms or ions together
Bond length
Distance between two bonded atoms at their minimum potential energy
Bond angle
Angle formed by two bond stop the same atom
Hydrogen bond
Force when hydrogen atom that is bonded to another atom of one molecule
Ionic bond
Bond formed by the attraction between oppositely charged ions
Metallic bond
Bond formed by the attraction between positively charged metal ions and electrons
Covalent bond
Bond formed when atoms share one or more pairs of electrons
Polyatomic ion
Ion made of two or more atoms
Formula unit
formula of any ionic or covalent network solid compound used as an independent entity
Nonpolar covalent bond
with equal sharing of the bond electrons, arise when the electronegativities of the two atoms are equal.
Polar covalent bond
electrons shared by the atoms spend a greater amount of time, on the average
Empirical formula
Composition of a compound of the relative numbers and kinds of atoms
Molecular formula
Chemical formula that shows number and kinds of atoms in a molecule
Organic compound
Bonded compound that contains carbon
Polymer
Large molecule that is formed by more than five small units
Carbohydrate
Any organic compound made of carbon oxygen and hydrogen
Protein
Organic compound made of one or more chains of amino acids
Amino acid
Organic molecules that contain a carboxyl and a amino group
Hydrocarbon
organic compound consisting of hydrogen and carbon
Alkane
consist of hydrogen and carbon atoms and all bonds are single bonds
Alkene
unsaturated hydrocarbon that contains at least one carbon–carbon double bond
DNA
Determines genetic makeup
