metals to nonmetals
In ionic bonding, electrons are usually transferred from these types of atoms (A) to these types of atoms (B).
In covalent bonds, bonding usually occurs between these types of atoms.
Ions with positive charges--usually metals of Groups 1A, 2A, and 3A.
A nonmetal ion is named by changing the end of its name to:
Negatively charged ions (nonmetal) are also called:
Have nonmetal ions from Groups 5A, 6A, & 7A lost or gained 3, 2, or 1 electrons, respectively?
An atom whose outer valence shell is less than half-filled will lose electrons and form a positively charged ion, called a/an
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
This bond is an attraction between atoms of opposite charge.
This bond is formed by two atoms sharing one or more pairs of electrons.
T or F: Ionic bonds are stronger and are far more common in organisms than are covalent bonds.
Hydrogen & Carbon, whose outer electron shells are half-filled, form this type of "sharing" bond quite easily.
A roman numeral after a transition metal indicates its a) positive or b) negative charge.
This is a group of atoms that share the same electrical charge. Names of these groups must be memorized.
Name of this polyatomic ion: OH^-
Name of this polyatomic ion: NH4^+
Name of this polyatomic ion: NO3^-
Name of this polyatomic ion: ClO3^-
Name of this polyatomic ion: CO3^2-
Name of this polyatomic ion: SO4^2-
Name of this polyatomic ion: PO4^3-
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.
T or F: When naming the 2nd nonmetal in a covalent bond, -ide should be added.
