21. Answer the following questions…
Identify the compound associated with the given information:
a. low melting point.
b. hard object.
c. nonelectrolyte.
When the following elements become ions, identify their new electron configuration? Which noble gas configuration does it match?
a. Phosphorus.
b. Rubidium (Rb).
c. Bromine.
Identify the type of bond formed. Ionic or covalent?
a. electronegativity difference = 2.7
b. metal + nonmetal.
c. strong bonds formed.
d. nonmetal + nonmetal.
e. polyatomic ion + polyatomic ion.
f. electronegativity difference of 1.0
The greater the electronegativity difference between the 2 elements, the __________ the IONIC CHARACTER.
The closer the electronegativity between 2 elements to zero, the __________ the COVALENT CHARACTER.
If a compound of one metal and one nonmetal have a electronegativity difference of 1.2, would the compound be considered ionic or covalent? Why?
