The periodic table is a catalogue of all the known elements, and it's safe to say that this universe wouldn't exist if these elements didn't combine. Each element is characterized by an atom with a certain number of protons and neutrons in its nucleus and a certain number of electrons s...
The scientific study of matter's characteristics and behaviour is known as chemistry.andare different from the normal vocabulary. It is a branch of natural science that examines the building blocks of matter, including the atoms, molecules, and ions that make up compounds and their composition, s...

The noble gases seemed at first to violate all the known rules of chemistry, but came to play a central role in our understanding of the chemical forces that bind all substances together. The really interesting fact about them, scientifically speaking, is their almost total lack of chemical ...
What is HCl gas? Answer and Explanation:1 Chemical compounds are created when two or more chemical elements bond together. Each chemical compound has a specific chemical formula. For example,... Learn more about this topic: Hydrochloric Acid | HCl Formula, Chemical Properties & Uses ...
What is noble gas notation? Electron Configuration: The current model of the atom is the quantum mechanical model. In this model, each element has a unique electron configuration. Noble gases are the family of elements that are nonreactive because their valence electrons are full. ...

What is a molecule? A molecule is two or moreatomsconnected by chemical bonds, which form the smallest unit of a substance that retains the composition and properties of that substance. Molecules form the basis of chemistry. Molecules are noted with theelementsymbol and a subscript with the num...
cases, the phosphorus and chlorine atoms are connected by covalent bonds. PCl3assumes the expected noble gas structure, in which the atoms achieve complete outer electron shells. Yet PCl5is also stable, so it's important to remember covalent bonds in chemistry don't always abide by the octet ...
