The non-metal A is an important constituent of our food and most of the fuels around us.

Hi, I have a question and I hope anyone could answer it:

The non-metal A is an important constituent of our food and most of the fuels around us. A forms two oxides B and C. The oxide B is poisonous whereas oxide C causes global warming.

(a) Identify A, B and C.

(b) To which group of periodic table does A belong?

(c) Name another element which is placed in the same group as A.

    2. Answer:

      (a) Identification of A, B, and C

      (1) A is Carbon(C). Carbon is an important constituent of our food as compounds of carbon are present in the food that we eat, the clothes that we wear etc.

      (2) B is Carbon monoxide(CO).

      • Carbon monoxide is a colourless and odourless gas that is produced by the incomplete combustion of materials containing carbon.
      • Carbon monoxide poisoning can result in brain damage and even death as it has more affinity to combine with haemoglobin than Oxygen (O2)

      (3) C is Carbon dioxide (CO2).

      • Carbon dioxide is a major contributor to global warming.
      • Global warming: It is the gradual increase in the earth’s temperature generally due to the greenhouse effect caused by increased levels of carbon dioxide, CFCs, and other pollutants.

      (b) Group of element A in the periodic table

      • Electronic configuration of Carbon = 1s22s22p2
      • As the last electron enters in p-subshell, so carbon is a p-block element.
      • For p-block elements, Group number= 12+ Number of electrons in p-subshell
      • Therefore, Group number= 12+ 2= 14
      • Hence, carbon belongs to Group 14.
      • 112
    4. (a) A is carbon (C), B is carbon monoxide (CO) and  C is carbon dioxide (CO2​ )
       
      (b) Carbon belongs to 14th group 
       
      (C) Silicon (Si) which is placed in the carbon family (same group).
