Elements in the same group have similar properties
The number of protons in an atom's nucleus
Elements with lower atomic masses are more reactive

Answer 1

The correct statement that explains how the periodic table helps to predict the properties of elements is:

Elements in the same group have similar properties.

Elements that are grouped together in the same column (or group) of the periodic table tend to exhibit similar chemical and physical properties due to their similar electron configurations. This grouping allows scientists to make predictions about how an element might behave based on the characteristics of other elements in the same group.
