Fluorine is the most chemically active nonmetal on the planet. It is highly reactive and can form compounds with almost all elements due to its strong electronegativity.
True
True. The majority of elements on the periodic table are solids at room temperature and pressure.
true
The most reactive nonmetal is fluorine
False. Most minerals are compounds, which means that they are combinations of elements. Additionally, some minerals are elements by themselves.
The noble gases.
It nonmetal ! I know this one! I had it on a worksheet!
Sulfur is classified as a nonmetal.
No, metals are not compounds. They are elements or mixtures (alloys) containing metallic elements.
True Niqquh!
Francium is the most reactive metal and fluorine the most reactive nonmetal.
False. Most minerals are compounds, meaning they are composed of two or more elements bonded together. This is what gives minerals their unique chemical and physical properties.
