61
What is the correct chemical formula for aluminum oxide?
Al₂O₃
62
What is the atomic number of an element, and why is it important?
The atomic number is the number of protons in an atom's nucleus, and it defines the element and its position on the periodic table.
63
What are transition metals, and where are they located on the periodic table?
Transition metals are elements located in the center of the periodic table. They are metals that can form multiple oxidation states.

Why do ionic compounds conduct electricity in their liquid or dissolved states, but not in their solid states?
In their liquid or dissolved states, ions are free to move, allowing electrical conductivity. In their solid states, ions are fixed in place and cannot conduct electricity.
65
What is the difference between a molecular and an ionic compound?
A molecular compound is formed by covalent bonds between nonmetals, while an ionic compound is formed by the transfer of electrons between a metal and a nonmetal.
66
How is the average atomic mass of an element calculated?
The average atomic mass is calculated by taking the weighted average of the masses of all stable isotopes of the element.
