Ionic bond
formed between oppositely charged ions
-bond is formed by electron transfer (simultaneous loss and gain of electrons to form
oppositely charged ions), these oppositely charged ions then attract one another.
Covalent bond
-formed by electron sharing where the two atoms nuclei attract the same group of
electrons, thus remaining bonded to one another
-two types: polar and nonpolar
-share either one pair (single covalent), two pairs (double covalent), three pairs (triple
covalent)
Polar covalent bond
-formed by unequal sharing of electrons by nonmetal elements of somewhat different
electronegativities
Nonpolar covalent bond
-electrons are shared equally
Cation
-positively charged ion, because it is attracted to the negatively charged pole (cathode)
of an electric field
-formed by charged particles formed by an atom either losing one or more electrons
Anion
-negatively charged ion, because it is attracted to the positively charged pole (anode) of
an electric field
-formed by an atom gaining one or more electrons to form a negatively charged ion
Bond
a group of negatively charged valence electrons between the atoms that is
simultaneously attracted by the positively charged nuclei of both atoms
