How are metalloids related to metals and nonmetals?
Question 2 options:
Metalloids serve as a divider between metals and nonmetals.
Metalloids show all the properties of metals and nonmetals.
Metalloids do not show properties of metals or nonmetals.
Metalloids show some properties of both metals and nonmetals.
Metalloids show some properties of both metals and nonmetals.

The way a surface appears when it reflects light.
To determine which element in the table is classified as a metal, you need to refer to the periodic table. The periodic table is a tabular arrangement of chemical elements, where each element is represented by its atomic number, symbol, and atomic mass. The elements are grouped into different categories or groups based on their properties.
In this case, you need to identify the element that is classified as a metal. Metals are usually found on the left side of the periodic table and are characterized by having properties such as being good conductors of heat and electricity, malleability, and being able to form positive ions.
Looking at the options provided:
1. Manganese: Manganese, represented by the symbol Mn, is classified as a metal. It can be found in the transition metal section of the periodic table.
2. Sulfur: Sulfur, represented by the symbol S, is not classified as a metal. It is a nonmetal and is found in the nonmetal section of the periodic table.
3. Silicon: Silicon, represented by the symbol Si, is not classified as a metal. It is a metalloid, which means it has properties intermediate between metals and nonmetals.
4. Neon: Neon, represented by the symbol Ne, is not classified as a metal. It is a nonmetal and is found in the nonmetal section of the periodic table.
So, in this case, the element Manganese (Mn) is classified as a metal.
