Physical Properties – Ionic Compounds

Structure Ionic Compound In an ionic compound, the alternate positive and negative ions in an ionic solid are arranged in an orderly way as shown in the image to the right. The ions can form a giant ionic lattice structure¬†with ionic bond between the ions. The ionic bond is the strong electrical attraction (electrostatic force) … Read more

Covalent Bonding

Covalent Bonding Covalent bonds are formed by atoms sharing electrons to form molecules. This type of bond usually formed between two non-metallic elements. In the formation of covalent bonds, atoms of non-metals will combine with each other to donate one, two or three electrons for sharing. The compound formed through the formation of covalent bonds … Read more

Ionic Bonding

Ionic Bonding Ionic bonds are formed by one atom transferring electrons to another atom to form ions.¬† Ions are atoms, or groups of atoms, which have lost or gained electrons. The atom losing electrons forms a positive ion (a cation) and is usually a metal. The atom gaining electrons forms a negative ion (an anion) … Read more

Formation of Ion

Formation of Ion An ion is an atom or group of atoms carrying positive or negative charge. Example Ca2+, O2-, SO42- etc. If a particle has equal numbers of protons (+) and electrons (-), the particle charge is zero, and the particle is said to be neutral. In a chemical reaction, electron(s) can be transferred … Read more

Chemical Bond

Stability of Noble Gases Stability of Noble Gases Group 18 elements (Noble Gases) exist as monoatom in nature. They are inert in nature and do not react with any other elements (or themselves) to form any chemical compounds. In other words, they are chemically very stable (or chemically very non-reactive).
