Explanation:
Liquefied Petroleum Gas (LPG) primarily consists of butane (C₄H₁₀) and isobutane, with some propane. For domestic use, it is often a mix of butane and propane. Methane is the main component of CNG and natural gas, which require different storage pressures and infrastructure.

Explanation:
Ernest Rutherford, in 1911, along with Geiger and Marsden, bombarded a thin gold foil with alpha particles. Most passed through, some were deflected at large angles, leading to the nuclear model of the atom—a small, dense, positively charged nucleus with electrons around it. Thomson's plum pudding model predicted no large deflections. Chadwick discovered neutron.
