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. ...
neon, argon, krypton, xenon and radon. All of these elements are gaseous at room temperature, colorless, odorless and unreactive with other elements. The noble gases share an electron configuration in which the outer, or valence, atomic orbitals are completely filled. ...

What is the charge of the nucleus of an oxygen atom? Identify the central atom (or atoms) in the given ion. What atom has the smallest radius among the chalcogens? Which element is a noble gas with 18 protons in the nucleus?
Oar (n) An implement for impelling a boat, being a slender piece of timber, usually ash or spruce, with a grip or handle at one end and a broad blade at the other. The part which rests in the rowlock is called the loom. Oar (n) An oarsman; a rower; as, he is a good oar...

When the outer shell is "unfilled" or the required number of electrons is not yet complete, the atom is more reactive. Noble gases have a full outer shell, meaning that they have complete electrons in their outer shell. This complete number varies. For instance, the outer shell of Helium ...
Atomicity refers to the number of atoms in a molecule, like O₂ having an atomicity of two. Valency is the combining capacity of an element, indicating how many bonds an atom can form with others, like oxygen having a valency of two. ...
Valency is the combining capacity of the elements to form compounds. During the formation of the molecules of the compounds, atoms combine in certain fixed proportions. Visit BYJUS to learn more about it.
