Final answer:
There are currently 118 known elements, which can be classified into metals, nonmetals, and metalloids.
Step-by-step explanation:
The elements are the building blocks of matter, and they are classified into different types based on their properties and characteristics. Currently, there are 118 known elements on the periodic table. These elements can be categorized into metals, nonmetals, and metalloids.
Metals, such as iron and gold, are typically shiny, malleable, and good conductors of heat and electricity. Nonmetals, like oxygen and nitrogen, are usually gases or brittle solids and have poor conductivity. Metalloids, such as silicon and boron, possess some properties of both metals and nonmetals.
It is important to note that new elements may be discovered in the future, expanding our understanding of the types of elements that exist.
