positive electric charge of 1 elementary charge. The name proton was given to the hydrogen nucleus by Ernest Rutherford in 1920. The concept of a hydrogen-like particle as a constituent of other atoms was developed over a long period. As early as 1815‚ William Proust proposed that all atoms are composed of hydrogen atoms‚ based on a simplistic interpretation of early values of atomic weights ‚ which was disproved when more accurate values were measured. In 1886‚ Eugene Goldstein discovered canal rays and

The Formation of the Solar System is one of the oldest problems in science. There have been many theories on how the Solar System formed‚ but there is only one theory that has been accepted. That would be the nebular theory. Also known as the nebular hypothesis and solar nebula hypothesis. The nebular hypothesis is a model that explains the evolution of the Solar System. Also‚ the nebular hypothesis is the most accepted model in the field of cosmogony. This model explains subjectively many features

The Solar System The solar system still to this day one of the most fascinating subjects of study in the science world. In our time‚ we are one of the first generations to see the planets of our solar system up close‚ and we have been able to view evolution of these planets through time. Our solar system consists of a middle aged star called the Sun‚ 9 planets‚ about 100 moons‚ thousands of asteroids‚ millions of icy bodies‚ and many comets revolving around all of it. We can begin by looking

Solar System For Households As the development of technology is flourishing‚ fossil fuels are unceasingly depleted for enormous generation of energy. With limited resources‚ alternative forms of renewable energy are emerging. Among them‚ solar power has been growing at a blistering pace in recent years. It sparks controversy among different parties. Some people applaud this method saying it is more environmentally friendly; while some others express resentment on the astronomical cost of building

Economic effect of Solar Panel Technology on our Society. Solar energy and its use isn’t new to the world. It has been used by various societies beginning from 7thCentury B.C‚ when the sun’s heat was concentrated by glass and mirrors to light fires. Today‚ we have everything from solar-powered buildings to solar-powered vehicles. By and large solar technology has some environmental‚ economic‚ psychological and ethical implications for our society. Actions

Ernest Rutherford was a New Zealand physicist and chemist who earned the title “Father of Nuclear Physics” after his discoveries of radioactive half-lives‚ differentiated between alpha and beta radiation‚ and proved that radioactivity involved the transmutation of one chemical element to another. He is also the recipient of the 1908 Nobel Prize in Chemistry "for his investigations into the disintegration of the elements‚ and the chemistry of radioactive substances". Ernest Rutherford was born

are 8 planets in our solar system; these are divided into two types‚ large gas giants (Jupiter‚ Saturn‚ Uranus and Neptune) and smaller rocky terrestrial planets (Mercury‚ Venus‚ Earth and Mars). The order from closest to the Sun outwards is; Mercury‚ Venus‚ Earth‚ Mars‚ Jupiter‚ Saturn‚ Uranus and finally Neptune. Until 2006 Pluto was also classed as a planet‚ however it is now classified as a dwarf planet (meeting the first two requirements of the definition but not the third). A planet is currently
