Flashcards in Lecture 2 Deck (20):
An attraction between two atoms resulting from a sharing of of outer shell electrons or presence of opposite charge on atoms
The making and breaking of chemical bonds leading to changes in composition matter.
A substance consisting of two or more different elements combined in fixed ratio
A type of strong chemical bond in which two atoms share one or more parts of valence electrons.
An energy level of electrons at characteristic average distance from the nucleus of an atom.
A subatomic particle with a single negative electrical charge and mass. One or more electrons move around the nucleus of an atom.
Any substance that can't be broken down by chemical reactions.
Weak chemical bond that's formed when the positive hydrogen atom of a polar covalent bond is one molecule is attracted to the negative atom of a polar covalent bond in another molecule.
An atom that has gained or lost one or more electrons thus Acquiring a charge.
A chemical bond resulting from the attraction between oppositely charge ions.
One of several forms of an element, each with same number of protons but different number of neutrons
A type of molecular notation representing the quantity of constituent atoms
The two or more atoms held together by covalent bonds
Subatomic particle with no charge.
A material resulting from a chemical reaction
Subatomic particle with a positive charge.
A starting material in chemical reaction
A type of molecular notation in which the constituent atoms are joined by lines representing covalent bonds
The bonding capacity of a given atom
