Flashcards in Chapter 3 Deck (27):
is the force of attraction between any two atoms in a compound
uses atomic symbol to represent the nucleus and core electrons and dots to represent valence electrons
involves a transfer of one or more electrons from one atom to another.
involves a sharing of electrons
is the electrostatic force, the attraction of opposite charges resulting cation and anion
Positive and negative ions arrange themselves in a regular three-dimensional repeating array to produce a stable arrangement
Covalent compounds consists of?
compounds containing only covalent bonds
are neutral (uncharged) species made up of two or more atoms joined by covalent bonds
List the most obvious examples of diatomic molecules?
H2, N2, O2, F2, Cl2, Br2, I2
Polar Covalent Bond
diatomic molecule composed of two different elements, not sharing electrons equally
measure of the ability of an atom to attract electrons in a chemical bond
ions consisting of a single atom
an example: OH- hydroxide ion, are composed of two or more atoms bonded together. These ions, although bonded to other ions with ionic bonds, are themselves held together by covalent bonds.
temperature at which a solid is converted to a liquid
is the temperature at which a liquid is covered to a gas a specified pressure
Ionic solids are?
crystalline, characterized by a regular structure
covalent solids are?
crystalline or have no regular structure (amorphous)
an ionic solid, if soluble, will form positive and negative ions in solution
three pairs of electrons are shared by two atoms
amount of energy in units of kilocalories
compounds that share the same molecular formula but have different structures
when a compound has 2 or more lewis structures that contribute to the real structure
ions consisting of a single charge
ions composed of 2 or more atoms bonded together with an overall positive or negative charge
ions present in solution allowing the solution to conduct electricity
covalent solids usually do not do what?
dissociate and do not conduct electricity
