Question

Consider occurance of the halogen family in the periodic table and choose true statements.
Statement I. Fluorine is the most active nonmetallic element in the periodic table.
Statement II. As you move down the family the state of the halogens is from a solid to a gaseous state.
Statement III. By filling the outermost d orbital, the halogen elements can be converted to ions.

• A. I and III
• B. II only
• C. I and II
• D. I only
  
• E. II and III

Answer 1

Answer: (D)

I only

Only statement I is the true statement.
Statement I. Fluorine is the most active nonmetallic element in the periodic table.
Statement II. As you move down the family the state of the halogens is from a gas to a solid state.
Thus, fluorine and chlorine are gases, bromine is a liquid and iodine is a solid.
Statement III. By filling the outermost p orbital the halogen elements can be converted to ions.
