Ionic compounds are arranged:
in solid crystalline networks lattices
In general, nonmetals.....than metals
...have higher ionization potentials and electronegativities, thus having a higher affinity for electrons...
The larger the difference in electronegativity between bonding atoms:
the more polar the bond
A metal ion, or a positively charged ion is called
a cation
A nonmetal, or negatively charged ion is called
an anion
Properties of ionic compounds are determined by...and...
charge;size
Interactions between ions are determined by
Coulomb's law F = (q1*q2) / (r^2)
During the formation of ionic compounds, atoms in the metal.....electrons while those of the nonmetal....electrons
lose;gain
How would you expect the size of each type of atom to change when becoming ions?
Cations are smaller than neutral atoms (they occupy less space due to less electrons) Anions are larger than neutral atoms (they occupy more space due to more electrons)
How would you expect the periodic trend for ion sizes to be?
Radius increases as you move left and down
One may expect electrostatic forces among ions to be stronger (based on Coulomb's law)....
the larger the charge of the ions and/or the smaller the size of the ions
T/F? Ionic compounds tend to have high melting/boiling points because electrostaic forces are strong?
True
Ionic compounds that are INSOLUBLE in water are comprised of ions that have...
large charge and small size
Ionic compounds that are SOLUBLE in water are comprised of ions that have...
small charge and large size
A simple rule to make predictions about the solubility of ionic compounds based on ion charge is:
Multiply the charges together, if = 4 or more, then it is SOLUBLE
Hydroxide ion
OH ˉ
Nitrate ion
(NO3)ˉ
Sulfate ion
(SO4)ˉ2
Phosphate ion
(PO4)ˉ3
Carbonate ion
(CO3)ˉ2
Ammonium ion
