Answer 2

(c) (i) Graphite, (ii) hydrogen, (iii) sulphur, (iv) nitrogen.

Explanation:

• Graphite: A large number of delocalised electrons makes graphite a very good conductor of electricity. Graphite is an allotrope of carbon.
• Hydrogen: It is used for welding due to the enormous amount of heat release from atomic hydrogen.
• Chlorine: Elements like chlorine and Iodine have properties that prevent infection at the site of a wound. Other than antiseptics, these elements are also used as disinfectants.
• Nitrogen: It is an inert gas and therefore it does react with food content which preserves its taste and texture.
