Question

How many if the element shown are metals? how many are nonmetals? how many are metalloids?

Answer 1

Based on the image below that is attached to the question, the numbers of elements that are metals, non metals or metalloids are: 0 metals, 5 nonmetals, and 3 metalloid

Metals are elements that have a shiny appearance, are malleable (can be hammered into sheets) and ductile (can be pulled into wires), and are good conductors of heat and electricity. They also tend to lose electrons easily to form positive ions.

Nonmetals are elements that do not have the properties of metals. They are typically dull or brittle, are poor conductors of heat and electricity, and do not lose electrons easily.

So, the elements in the image are:

1. Silicon (Si)
2. Phosphorus (P)
3. Sulfur (S)
4. Chlorine (Cl)
5. Germanium (Ge)
6. Arsenic (As)
7. Selenium (Se)
8. Bromine (Br)
