A certain element X was found for 3 compounds with chlorine having the formulas XCL2, XCL4, XCL6. ONe of its oxides has the formula XO3 and X reacts with sodium to form the compound Na2X.
a. Is X metal or nonmetal?
b. which group of the periodic table is X located?
c. In which periods of the table could X be located?
d. Which of the formulas in the problem have multiple bonding?
e. Which are polar?
f. What kind of hybrid oribitals would X use for bonding in XCL4 and XCL6?
g. If X formed a compound with aluminum, what would the formula be?
h. Which compound of X would have the most ionic bonds, Na2X or MgX?
i. If X were in period 5, what would the electron configuration be of its valence shell?
Please help. I think I got the other ones. I figured out the lewis structures on my own and hope they are right, but I need these questions answered
