Air contains approximately 78% nitrogen, 21% oxygen and the final 1% is made up of argon, carbon dioxide and trace amounts of other gases. There is a possibility that air could also contain many bacteria and viruses from humans sneezing.
The noble gases.
If you think to sodium chloride (NaCl) this contain Na and Cl (halogen).
All common oxoacids contain hydrogen and oxygen. In addition to these elements, they typically also include a central element, which is usually a nonmetal such as sulfur, phosphorus, or nitrogen. These central elements contribute to the acid's specific properties and strength.
The most reactive nonmetal is fluorine
The halogens.
The noble gases.
Atoms of all chemical elements contain protons, neutrons and electrons.
If you think to sodium chloride (NaCl) this contain Na and Cl (halogen).
Most commonly, oxyacids contain 3 elements. They must contain Oxygen, Hydrogen, and a central atom that can be a variety of different elements. Here are some examples: HClO HBrO4- HIO
elements
Fluorine is the single most reactive nonmetal, with oxygen and chlorine close behind.
Nitrogen is a nonmetal.
All common oxoacids contain hydrogen and oxygen. In addition to these elements, they typically also include a central element, which is usually a nonmetal such as sulfur, phosphorus, or nitrogen. These central elements contribute to the acid's specific properties and strength.
Carbon, oxygen, and hydrogen are all nonmetal elements.
Aluminum combines chemically into binary compounds mostly with nonmetal elements, but aluminates, which contain oxygen, aluminum, and another metal element are also important minerals practically.
The most reactive nonmetal is fluorine
Yes, most molecular compounds do not contain metals. (The term "nonmetal" properly applies only to elements, not compounds.)
