the alpha particle. Ernest Rutherford tested the structure of an atom by bombarding a thin sheet of gold foil with alpha particles. Most of the alpha particles passed though the atom but some reflected or even bounced of the gold foil. Rutherford concluded that there was a positive group of particles in the centre of the atom he revised Dalton’s original model and said that atoms were made up of a positive nucleus of protons and that the electrons orbited this centre. He was unable to explain why the electrons orbited the nucleus and did not spiral inward as they lost
Hydrogen bombs are more than 1000 times more powerful than the very common atomic bomb. The explosion is from nuclear fusion which is when hydrogen nuclei (plural of nucleus) are joined to form helium nuclei, releasing great destructive energy and radioactive fallout. When the nuclei combine there is a split second where there is nothing and then there is the explosion. An atomic bomb is the trigger or the smaller bomb of what sets off the hydrogen bomb. We have to be careful with the hydrogen bomb because, if used, it will cause a major catastrophe far greater than the damage done by the atomic bomb.
In nuclear fusion, energy is released when atoms are combined or fused together to form a larger atom. The sun produces energy like this. But in nuclear fission, atoms are split into smaller atoms, releasing energy. Actually, nuclear power plants can only use nuclear fission to produce electricity. Nuclear generation is the only source of electricity that can produce large amounts of power known as base load power—reliably without emitting greenhouse gases.
Alkaline Earth Metals IS made up of six elements. It’s the second group on the periodic table. All alkaline earth metals have an oxidation number of +2, making them very reactive. Because of their reactivity, the alkaline metals are not found in nature.All of the Alkaline earth metals except magnesium and strontium have at least one naturally occurring radioisotope Noble Gases is made up of six elements on the periodic table which are in the last group on the periodic table. There are actually now seven elements in the noble gases.
A star that goes by the name of Trappist 1 (named after the small telescope in Chile TRAnsiting Planets and PlanetesImals Small Telescope–South)has orbiting planets in the constellation Aquarius. Trappist 1 is about 40 light years away from Earth and is 12 times less the size of the sun but only a little bit bigger than Jupiter. Out of these seven planets, three of them are best suited for life. These planets are part of the Goldilocks Zone, they have the right amount of energy from their host star that oceans could exist. A group of astronomers found these planets by using a method called the transit method of planetary detection.
In this diagram, a neutron is absorbed by a uranium-235 nucleus, as a result, it turns of a small period of time to an excited uranium-236 nucleus, with the excitation energy provided by the kinetic energy of the neutron plus the forces that bind to the neutron. The uranium-236 then splits into two, smaller, lighter, fast-moving elements (these are known as fission products) and releases three free neutrons as well as gamma rays. Fusion and fission are nuclear reactions. Fusion is the binding of two atoms to produce a heavier atom while fission is splitting of an atom. Fusion releases more energy than fission and powers the stars.
Four images of the quasar show up around the galaxy due to the intense gravity of the galaxy that bends the light coming from the quasar. Gravitational lensing can enable scientists to spot some pretty cool things, but so far, what they observed around the lens has remained fairly static. In another interesting observation, NASA’s Kepler telescope caught sight of a dead star, known as a white dwarf, orbiting a red dwarf in a binary system, Although, the white dwarf is heavier, it has a far smaller radius compared to its companion. According to Avi Shporer of California Institute of Technology, the technique is similar to spotting a flea on a light bulb 3,000 miles away which is approximately the distance from Log Angeles to New York
This helped prove his theory of the proton’s existence because when the alpha radiation occurred it turned the old element into a new element by removing two protons. Lastly the article also mentions that, “In 1898, Ernest Rutherford began studying the radiation emitted by uranium. His experiments led him to conclude that radioactivity must have at least two components; and he named them alpha and beta rays after the first two letters of the Greek alphabet.” The research he conducted lead him to realized that beta rays were way more penetrating than alpha
The different gravitational pulls of the four types of stars show the different effects on space-time. The first star is our star in th center of the solar system referred to as the sun. The last star is a neutron star. Neutron stars are extremely dense star with a gravitational pull of two hundred billion times that of Earth. If a person lived on the sun in the center of our solar systems, and then traveled to a neutron star and lived there for one year, when the person went back to the sun he left, hundreds of years would have passed.
This same chain of reasoning suggests that gravity must also have some kind of quantum nature (Lincoln). Obviously if atoms functioned as proposed by general relativity, matter would fail to exist in the universe. If scaling relativity down fails to make sense, applying quantum mechanical theory on a relativistic scale would be a logic next step. Physicists quickly found that quantum field theory fails to account for the warping of spacetime proposed and observed by general relativity. Paul Stutter, an Astrophysicist and journalist for Space.com summarizes the complexities of these factors
Atoms are the smallest bit of matter. They are matter and matter is them. Atoms are made of multiple things. Their layout is a dense nucleus surrounded by a large cloud of electrons. The “cloud” of electrons surrounding the nucleus give off a negative charge.
Facts One day on Venus is 243 Earth days One year on Venus is 225 earth days Venus’s radius is 3,760 miles or 6,052 kilometers Venus is classified as a Terrestrial Venus has no moons This planet being called a Terrestrial means that they are Earth like planets made up of rocks and metals with a hard surface. This makes these planets different than the others planets that lack solid surfaces. Terrestrial planets also are made up of heavy molten cores and valleys, volcanoes, and craters. Finder Venus has been one of the easiest planets to see in the sky science the early lives of civilization and it is not clear to say that one person found Venus science anyone back in the day could just look up into the sky and see a reddish yellow star along
Mass it’s a measure of matter in any given object 3. Atom are composed of tiny pieces of matter composed of constituent parts A: Protons. Neutrons and Electrons 1. Protons (positive charge) combined to form an atom 2. Neutron (no charge) combined to form an atom 3.
It is about 1,550 kilometers (960 miles) in diameter. It was formed by the impact of a large meteorite in the formation of the solar system. The Caloris Basin has been found to be a significant source of sodium and potassium. Instead of an atmosphere, Mercury has a thin exosphere made up of atoms and micrometeoroids. Because of the planet’s extreme temperatures, the atoms quickly disappear into space.
Mars has two satellites, unlike Venus who has no natural satellites. Mars’s two satellites are Phobias and Demos, which scientist believed are captured asteroids. Mars was named after the God of War. Interestingly, this is the complete opposite of love, the god that Venus was named after. Mars does not have as many volcanoes as Venus.
