The valency of an element refers to its combining capacity, determined by the number of electrons an atom gains, loses, or shares to achieve a stable electronic configuration. The valency of Chlorine (Cl), Sulphur (S), and Magnesium (Mg) can be found using their electronic configurations.<\/p>\n\n\n\n

Complete Answer<\/strong><\/p>\n\n\n\n

1. Valency of Chlorine (Cl)<\/strong><\/p>\n\n\n\n

Atomic number: 17
Electronic configuration: 2, 8, 7<\/p>\n\n\n\n

Chlorine needs 1 electron to complete its octet (8 electrons in the outer shell).<\/p>\n\n\n\n

Valency of Chlorine<\/strong> = 1 (It gains 1 electron to form Cl\u207b in ionic bonding).
Example<\/strong>: Chlorine combines with sodium to form NaCl (Sodium chloride or table salt).<\/p>\n\n\n\n

2. Valency of Sulphur (S)<\/strong><\/p>\n\n\n\n

Atomic number: 16
Electronic configuration: 2, 8, 6<\/p>\n\n\n\n

Sulphur needs 2 electrons to complete its octet.<\/p>\n\n\n\n

Valency of Sulphur<\/strong> = 2 (It gains 2 electrons to form S\u00b2\u207b in ionic bonding).
Example:<\/strong> Sulphur forms compounds like H\u2082S (Hydrogen sulphide) and SO\u2082 (Sulphur dioxide).<\/p>\n\n\n\n

3. Valency of Magnesium (Mg)<\/strong><\/p>\n\n\n\n

Atomic number: 12
Electronic configuration: 2, 8, 2<\/p>\n\n\n\n

Magnesium loses 2 electrons to achieve a stable configuration.<\/p>\n\n\n\n

Valency of Magnesium<\/strong> = 2 (It loses 2 electrons to form Mg\u00b2\u207a in ionic bonding).
Example<\/strong>: Magnesium forms MgCl\u2082 (Magnesium chloride) and MgO (Magnesium oxide).<\/p>\n\n\n\n

Did you know that magnesium burns with a bright white flame? This is why it is used in fireworks and flares! Understanding valency helps in predicting chemical bonding and reactions, making it essential in chemistry.<\/p>\n\n\n\n
