SOL Review PS.4 Level 3

How does the periodic table help in predicting the reactivity of an element based on its position?

• By showing the atomic mass of the element.

• By arranging elements in order of increasing atomic number, which reveals patterns in reactivity.

• By listing elements alphabetically.

• By displaying the color of the element.

Given the position of an element in the periodic table, how can you predict its chemical properties?

• By its atomic mass.

• By its group and period, which indicate similar properties to other elements in the same group.

• By its color.

• By its density.
