Carbon has 4 valence electrons; it forms four covalent bonds by sharing electrons to achieve octet. It does not form ionic bonds easily due to high ionization energy and electron affinity.
Explanation:
Ammonia (NH₃) is manufactured by the Haber process, which involves the direct combination of nitrogen and hydrogen gases at high pressure (200 atm) and moderate temperature (450°C) in the presence of an iron catalyst. The Contact process is for sulfuric acid, and Ostwald's is for nitric acid.
Explanation:
J.J. Thomson discovered the electron in 1897 using cathode ray tubes and determined its e/m ratio. Rutherford discovered the nucleus; Chadwick discovered neutron; Bohr proposed quantized model.
Explanation:
CNG (Compressed Natural Gas) is primarily methane (CH₄). LPG is propane and butane. Methane is the lightest hydrocarbon. CNG is a cleaner fuel for vehicles.
