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 (Fig. 8.3)...

The hydronium ion is a hydrogen ion in association with a molecule of water. In a water molecule, the oxygen atom has two pairs of unshared electrons in its outermost shell. The hydrogen ion does not have any electron in its valence shell. Hence it shares a pair of electrons from the oxygen a..

Hydronium Ion - The hydronium ion is a hydrogen ion in association with a molecule of water. In a water molecule, the oxygen atom has two pairs of unshared electrons in its outermost shell. The hydrogen ion does not have any electron in its valence shell. Hence it shares a pair of electrons from th..

Chemical bond is the force of attraction, which holds the various chemical entities in different species. Electrovalent bond is the attractive force between the oppositely charged ions, which comes into existence by the transference of electrons. Electrovalency is the number of electrons, w..

. Thus bond strengths of the compounds decrease as we move down the group. For example, lithium has relatively high heat of atomization, melting and boiling points, density and hardness. The first member will have a higher electronegativity than other group members and shows greater property to for..

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..
