Other elements exist as gases at STP but as monatomic noble gases. A gas is monatomic when it is comprised entirely of one kind of atom, not bonded within any molecules. This contrasts with diatomic gases, which have their atoms bonded in pairs. Monatomic noble gases include the following el...
The formation of a monatomic ion depends on its electron configuration. Atoms are reactive because they have incomplete valence shells, meaning that their valence shells do not have the maximum number of electrons possible. Atoms of inert gases have complete sets of electrons in their valence shells...
Technically, a monatomic ion is a form ofmonatomic atom. However, the term "monatomic atom" usually refers to neutral atoms of elements. Examples include atoms of krypton (Kr) and neon (Ne). While krypton, neon, and other noble gases typically exist as monatomic atoms, they rarely form ion...
Monatomic – they exists as single atoms Unreactive – they do not normally react with anything. Why are Noble Gases unreactive? We know that atoms react with each other to gain full outer shells of electrons. Since the atoms of noble gases have full shells already, they have no need to...
Heat is supplied to the cylinder such that the temperature remains constant but n moles of the diatomic gas get converted into monatomic gas. What is the change in the total kinetic energy of the gas? A) 5/2 nRT B) 1/2 nRT C) 0 D) 3/2 nRT Solution: D) Initial K.E. = (3/...
Allotropes are forms of an element with different physical and chemical properties. The three allotropes of oxygen are normal oxygen, or diatomic oxygen, or dioxygen; nascent, atomic, or monatomic oxygen; and ozone, or triatomic oxygen. The three allotropes differ from each other in a number ...

The oxidation number of a free element is zero. The oxidation number of a monatomic ion equals the charge on the ion. The sum of oxidation numbers in a neutral compound is zero. The sum of all oxidation states in a polyatomic ion must equal the ion's charge. The oxidation number ...
