Answer: Boron (B) is located in Period 2 and Group 13 (also known as Group IIIA) of the periodic table.
Explanation: The periodic table is organized into rows called periods and columns called groups.
Boron has an atomic number of 5, which places it in Period 2, as elements in the same period have the same number of electron shells.
Additionally, boron is in Group 13, which indicates that it has 3 valence electrons.
Elements in the same group share similar chemical properties due to having the same number of valence electrons.
Significance: Knowing the period and group of boron helps describe its position in the periodic table and its electronic configuration.
This information is valuable in understanding its chemical behavior and its relationship to other elements.
