CHAPTER 3 Flashcards
When a metal and nonmetal combine, the bond is __.
ionic
When two nonmetals combine, or a metalloid bonds to a nonmetal, the bond is____.
covalent
This result from the transfer of electrons from one element to another.
Ionic bonds
This result from the sharing of electrons between two atoms.
Covalent bonds
A ___ is a compound or element containing two or more atoms joined together with covalent bonds.
molecule
There are two types of chemical compounds:
Ionic and covalent
These are composed of positively and negatively charged ions held together by strong electrostatic forces
Ionic compounds
the electrical attraction between oppositely charged ions.
electrostatic forces
These are composed of individual molecules, discrete groups of atoms that share electrons.
Covalent compounds
It is the joining of two atoms in a stable arrangement.
Bonding
It is a favorable process because it always forms a compound that is more stable than the atoms from which it is made.
Bonding
Bonding involves only the ___ of an atom.
valence electrons
A main group element is especially stable when it possesses an ___ of electrons in its outer shell.
octet
Metals form:
Cations
Nonmetals form:
Anions
Anions are ____ than the atoms from which they are formed
Larger
Cations are _____ than the atoms from which they are formed
Smaller
Assigning an unambiguous name to each compound is called___.
chemical nomenclature
This have extremely high boiling points.
ionic compounds
A great many ionic compounds are ____ in water.
soluble
An ___ contains a substance dissolved in liquid water.
aqueous solution
A __ is a cation or anion that contains more than one atom.
polyatomic ion
This have very high melting points.
