metals to nonmetals
In ionic bonding, electrons are usually transferred from these types of atoms (A) to these types of atoms (B).
nonmetals
In covalent bonds, bonding usually occurs between these types of atoms.
cations
Ions with positive charges--usually metals of Groups 1A, 2A, and 3A.
-ide
A nonmetal ion is named by changing the end of its name to:
anions
Negatively charged ions (nonmetal) are also called:
gained
Have nonmetal ions from Groups 5A, 6A, & 7A lost or gained 3, 2, or 1 electrons, respectively?
cation
An atom whose outer valence shell is less than half-filled will lose electrons and form a positively charged ion, called a/an
anion
When an atom's outer electron shell is more than half-filled, the atom will gain electrons and form a negatively charged ion, called a/an
ionic bond
This bond is an attraction between atoms of opposite charge.
covalent bond
This bond is formed by two atoms sharing one or more pairs of electrons.
false
T or F: Ionic bonds are stronger and are far more common in organisms than are covalent bonds.
covalent bond
Hydrogen & Carbon, whose outer electron shells are half-filled, form this type of "sharing" bond quite easily.
positive
A roman numeral after a transition metal indicates its a) positive or b) negative charge.
polyatomic ion
This is a group of atoms that share the same electrical charge. Names of these groups must be memorized.
hydroxide
Name of this polyatomic ion: OH^-
ammonium
Name of this polyatomic ion: NH4^+
nitrate
Name of this polyatomic ion: NO3^-
chlorate
Name of this polyatomic ion: ClO3^-
carbonate
Name of this polyatomic ion: CO3^2-
sulfate
Name of this polyatomic ion: SO4^2-
phosphate
Name of this polyatomic ion: PO4^3-
true
T or F: When naming covalent bonds, a prefix is used to match the subscript before the element name in both the 1st & 2nd nonmetals.
true
T or F: When naming the 2nd nonmetal in a covalent bond, -ide should be added.
