Type of process of the forming of the ionic compounds - correct answer --
| | | | | | | | | | | | |
reaction is exothermic because of the lattice energy (it releases heat during
| | | | | | | | | | |
formation)
|
-transfer of electron from metals to nonmetals is endothermic
| | | | | | | |
ionic bond models - correct answer --high heat to break apart lattice (high
| | | | | | | | | | | |
|melting points) because there are no free electrons
| | | | | | | |
-nondirectional (as you move away from the center of the ion the forces are
| | | | | | | | | | | | |
|equally as strong in all directions)
| | | | | |
-ionic solids dissolve in water or melt, the cations and anions dissociate and
| | | | | | | | | | | |
|free ions to allow for electrical currents to flow through
| | | | | | | | |
ionic compound formulas - correct answer --always contain positive and
| | | | | | | | |
|negative ions | |
-in a chemical formula, the sum of the charges of positive cations and negative
| | | | | | | | | | | | |
|anions are equal | | |
-the formula of an ionic compound reflects the smallest whole number ratio of
| | | | | | | | | | | |
|ions
common names - correct answer --nicknames learned by familiarity
| | | | | | | |
systematic names - correct answer --determine from the chemical formula and
| | | | | | | | | |
vice versa
| |
, ionic compounds are made up of - correct answer -metals and nonmetals
| | | | | | | | | | |
electronegativity - correct answer --ability of an atom to attract electrons to
| | | | | | | | | | |
itself in a chemical bond
| | | | | |
-increases across a period and decreases down a group
| | | | | | | |
-larger the atom, the less ability it has to attract electrons to itself in a chemical
| | | | | | | | | | | | | | |
|bond
degree of polarity - correct answer --depends upon the electronegativity
| | | | | | | | |
difference between two bonding atoms
| | | | | |
-greater the difference, the more polar the bond
| | | | | | |
nonpolar (covalent) - correct answer --two atoms with the same
| | | | | | | | |
electronegativities form a covalent bond and share electrons equally
| | | | | | | | |
ionic bond in terms of polarity - correct answer --large electronegativity
| | | | | | | | | |
|difference (such as normally between a metal and nonmetal)
| | | | | | | |
polar covalent - correct answer --intermediate electronegativity change
| | | | | | |
effect of electronegativity on the bond type - correct answer -Small change (0-
| | | | | | | | | | | |
