The remaining elements, after accounting for the three quarters that are metals, are categorized as nonmetals and metalloids.

Here's a breakdown:

* Metals: These are the most common type of element, making up about 75% of the periodic table. They are generally good conductors of heat and electricity, malleable (can be hammered into thin sheets), ductile (can be drawn into wires), and shiny.

* Nonmetals: These elements generally have the opposite properties of metals. They are poor conductors of heat and electricity, brittle (break easily), and dull. Examples include oxygen, nitrogen, carbon, and sulfur.

* Metalloids: These elements fall somewhere in between metals and nonmetals. They have some properties of both. Metalloids are often semiconductors, meaning they can conduct electricity under certain conditions. Examples include silicon, germanium, and arsenic.

So, the three quarters of the elements that are not metals are split between nonmetals and metalloids.
