atomicity of oxygen

One molecule of nitric oxide contains one oxygen atom and one nitrogen atom. Thus, molecule of nitrogen = 1 atom molecule of oxygen = 1 atom or, 1 molecule of nitrogen =2 atoms 1 molecule of oxygen = ..

On reaction with the other substances, sulphurous acid takes away an atom of oxygen from them, thereby reducing these substances...

The middle carbon atom that attaches to three other carbon atoms in the carbon chain of an organic compound is called a tertiary carbon atom. ..

There are three p-orbitals namely 2p x 2p y and 2p z , which are directed in space along the x, y and z, coordinate axes respectively. By convention, z-axis is assumed to be the internuclear axis. The x and y-axes would then be perpendicular to the internuclear axis..

Like 1s-orbitals, 2s-orbitals combine by addition and subtraction of overlappingwavefunctions to form bonding and antibonding molecular orbitals. These are labeled as s 2s,and s *2s. These molecular orbitals have exactly the same shapes as s 1s and s *1s MOs ..

A hydrogen atom has a mass of 1.67 × 10 -27 kilogram. Express the mass of 4 × 10 2 hydrogen atoms in scientific notation. => 6.68 x 10 -25 kilogram or 6.68 x 10 29 kilogram or 6.68 x 10 -29 kilogram or 6.68 x 10 25 kilogram..

Atomicity is the number of atoms of an element present in one molecule of that element. They can be monoatomic (He), diatomic (H 2 ), triatomic (O 3 ) and polyatomic (S 8 ..

Hydrogen is diatomic (H 2 ) whereas alkali metals are monoatomi..

Therefore, oxygen molecule has 16 electrons. In the formation of molecular orbitals, the electrons in the inner shells are expressed as KK denoting ( s 1s) 2 ( s *1s) 2 .The remaining 12 electrons are filled in molecular orbitals. fig 1.20 - Molecular orbita..
