How does the periodic table help to predict the properties of elements?
*
1 point
Elements in the same group have similar properties
Elements in the same period have similar properties
The number of protons in an atom's nucleus
Elements with higher atomic numbers are more reactive
Elements with lower atomic masses are more reactive
The correct answer is:
Elements in the same group have similar properties.
The periodic table organizes the elements based on their atomic structure and properties. Elements in the same group have similar outer electron configurations, which contribute to their similar chemical behaviors and properties. This allows us to predict the properties of new elements based on their placement in the periodic table.
