Metals are primarily located c on the left side of the metalloid line not including the metalloids.
In the periodic table, elements are divided into three main categories: metals, nonmetals, and metalloids. The metalloid line runs diagonally from boron (B) to astatine (At) and separates metals from nonmetals. Most of the metals can be found to the left of this line, which includes groups 1, 2, and the transition metals. These elements share common characteristics such as being malleable, ductile, and good conductors of heat and electricity.
On the other hand, options a and b are incorrect because:
- Option a states that metals are on the right side of the metalloid line. This is not accurate, as that area mainly consists of nonmetals.
- Option b mentions the last group of the periodic table, which contains noble gases, not metals.
Thus, the correct placement for metals is firmly on the left side of the metalloid line, confirming them as the dominant category in that region of the periodic table.
