Verified step by step guidance1
Identify the position of calcium (Ca) in the periodic table. Calcium is located in Group 2, which is the alkaline earth metals group, and in Period 4.
Recall the general classification of elements based on their position: metals are typically found on the left and center of the periodic table, metalloids are found along the zig-zag line between metals and nonmetals, and nonmetals are on the right side.
Since calcium is in Group 2, which is well within the metals section of the periodic table, it is classified as a metal.
Understand that metalloids have properties intermediate between metals and nonmetals and are located near the staircase line, which calcium is not near.
Therefore, based on its position and group characteristics, calcium is classified as a metal.
