Q: The structure of 1F5 is based on which configuration?
Q: Which of the following substance has the least ionic character in its bond ?
Explanation: Ionic character is greatest in a combination between a metal and non-metal e.g., KCI NaCI, BaCl2. Carbon is not classified as metal. It is hard. brittle and amorphous element. 11 will have the weakest ionic character because the tendency to produce positive ions decreases rapidly across a period and increases downward within group.
Q: Which ion has the most shells that contain electrons?
Q: Which substance has greatest lattice energy ?
Explanation: Lattice energy is measure of how much stabilization result from packing of oppositely charged ions together in an ionic compound. MgO has greatest lattice energy. MgO is only substance of those listed with charges of positive two (4-2) and negative (-2).
