hydrogen like ions

Hydrogen like ions are those which contain only one electron. For e.g., He + , Li 2 + etc. The energy expression for these ions may be written as: ..

Hydrogen like ions are those which contain only one electron. For e.g., He + , Li 2 + etc. The energy expression for these ions may be written as: where Z is the nuclear charge, which is equal to the atomic number. For e.g., for He + , Z = 2..

This is formed by the combination of hydrogen atom containing one electron and hydrogen ion having no electron. Therefore, this ion has only one electron. ..

Hydrogen Ion Concentration - In 1909, Sorensen introduced a term for expressing the concentration of hydrogen ions, which give an idea about the acidic and basic characters of the aqueous solution. This term was called 'pH' which means the 'power of..

When ammonia is dissolved in water it forms ammonium ions (NH ) and hydroxyl (OH - ) ions by the formation of a co-ordinate covalent bond. This can be shown as follows. Bases and acids neutralize each other, therefore another way to define a base is 'a compound which reacts..

The electron releasing groups (like -OCH 3 , -CH 3 , -NH 2 etc) enhance the availability of unshared electrons on nitrogen and increases the basic strength. Electrons withdrawing groups like (-NO 2 , -CN, -X etc) affect the stability of an aromatic ammonium c..

(0.9%) - include sodium, potassium, calcium, magnesium, chlorine and radicals like sulphate, phosphate, et..

In a molecule of ammonia, the nitrogen atom has one pair of unshared electrons in its outermost shell. This pair of electrons is shared by a hydrogen ion, which has no electrons in its valence shell, to form an ammonium ion..

: Na, Mg, K, Ca g lose electrons S, O, F, Cl g gain electrons Most of these atoms try to attain the configurations of either neon (2,8) or argon (2,8,8). By the loss or gain of electrons a neutral atom is changed to an ion . Ions are charged atoms or a group ..
