Answer:
Fuel is very important for everyday activities. Day-by-day our fuel deposits are depreciating. We need to save fuel to have a better environment around us. The real danger in consuming fuel thoughtlessly is that it is drying up the earth’s resources. Fossil fuels like coal and oil and gas are non-renewable resources. Increasing usage is depleting their presence within the earth. To save our environment, we need to save fuel. In today's world fuels are undoubtedly ruling our world. Our basic needs are Roti, Kapada and Makaan. And, we need fuel to cook, to manufacture fabric, to produce building material and to build our sweet homes. So willingly or unwillingly we are dependent on fuels to live. We use fossil fuels such as coal, wood, natural gas, Petroleum and its derivatives like petrol, diesel, LPG, kerosene etc. Since the days of Industrial revolution, there has been a rapid growth and development in the entire globe. The machines in industries, transport vehicles and domestic appliances all use fossil fuels. Even though the world adopted electricity as a source of energy, we still need fossil fuels to produce electricity. Environment is an essential part of our life. It includes surrounding water, air, trees, wildlife, birds, minerals etc. Quality of our life depends on the quality of our environment. Our health is dependent both on ourselves and our environment. We need a clean environment to live healthy. Last four decades have seen tremendous growth in electric and electronic gadgets and appliances causing the demand for energy to go skyrocketing. Combustion of fossil fuels results in carbon dioxide and other greenhouse gases that have negative impact on environment and health. Overuse of fuels have initiated a breakdown of our ecosystem balance. As a consequence air we breathe is polluted with CO2, soot particles and harmful gases. A large number of people suffer from respiratory diseases. The local temperatures have risen. Climatic balance is broken. Global warming is causing icebergs at the Poles and ice caps on mountain peaks to melt at a faster rate. Greenhouse gases (fluorocarbons) are depleting the Ozone layer faster than ever before. Ozone layer shields us from harmful Ultraviolet radiation of the Sun. The holes in Ozone layer mean sunburns and skin cancer from exposure to UV rays. Many species of birds and oceanic creatures are getting extinct. Animals too suffer from pollution. The balance in Biodiversity has become an issue. Imbalance in food-chain results in Earth's ecosystem imbalance. To live we eat food, drink water and breathe air. If they are contaminated, then certainly our health is affected. Comparing in our minds strolling happily on a path in a village and along a busy city road. Certainly we would want a peaceful and clean environment for a morning walk to the park nearby. Fuel and energy saved is as good as produced. Fuel saved is more than driving away diseases and buying health. There are many ways to save fuel. We could use shared or public transport like trams and metros. We switch off engines while waiting for traffic signals. We take an exercising walk to nearby places. We use bicycle not just as a sport, but as a transport. We use more efficient fuels. We switch off gadgets and appliances when not in use. We use green vehicles and latest technology based machines. Also drive vehicles uniformly at recommended speeds and maintain properly to run at high mileage. We need to replace obsolete technologies with the latest. Simply, we could replace the domestic light bulbs by the efficient LED bulbs. Let's use more efficient LCD and LED computer monitors and TVs in place of the bulky old ones. Let us use more efficient and silent CNG based engines rather than the traditional noisy diesel engines. Use of geothermal heat and biomass energies efficiently and cheaply serve our needs locally in the vicinity. Use of solar boats could reduce pollution of water bodies. In rural areas people still use kerosene, wood and tree leaves for domestic cooking and heating. We need to upgrade their lifestyle so that fuel is saved and environment is saved. Wastage of food, water or other materials happens inadvertently. Reducing wastage indirectly saves fuel required to produce more food and other products. Induction stoves save on energy needed to cook. Imagine 10% savings in a billion houses in the world. Lets useless of traditional fuels and use more of clean renewable fuels like solar, wind, tidal, geothermal, biomass, Nuclear, hydro, biofuel and so on. Then we meet our demands as well as save our environment. We stay healthier too. This is what ultimately we want and the mankind needs. Instead of polluting our location and then searching for a better place to live in, we all live healthier and jollier by saving fuel.Read more on Sarthaks.com - https://www.sarthaks.com/160247/save-fuel-for-better-environment-and-health-essay-in-700-wordsxplanation:
Answer:
The elements in which the last electron enters in p subshell are collectively called P-block elements.
These elements consist of the four main groups of elements in the periodic table: alkali metals, alkaline earth metals, transition metals, and other nonmetals. The p-block elements are characterized by the presence of a valence shell, which contains p-orbitals. The p-orbitals are distinguished from the s-orbitals by their shape, with four lobes that point in the directions of the four cardinal points (north, south, east, and west).
The p-block elements are divided into four groups, based on their electron configurations. The first group is the alkali metals, which have one valence electron in the s-orbital and seven in the p-orbitals. The second group is the alkaline earth metals, which have two valence electrons in the s-orbital and six in the p-orbitals.
The third group is the transition metals, which have three valence electrons in the s-orbital and five in the p-orbitals. The fourth group is the other nonmetals, which have four valence electrons in the s-orbital and four in the p-orbitals.
These elements tend to form compounds in which the p-block elements are the central atom, and their reactivity is determined by the number of valence electrons they possess.
