Neptune, known for its glorious blue color, is 2.7 billion miles away. The nearest star, Proxima Centauri, is 24.92 trillion miles from the Earth. The nearest galaxy to us, the Andromeda Galaxy, is 1.492 times 10 to the power of 19. These distances, as we can see, get so large that astronomers use something called light years. This is the how far light travels in one year.
Venus rotates in the retrograde rotation, contrary to that of the other planets. Venus is the second brightest object in the sky, only being outshined by the moon. Venus has an atmospheric pressure that is 92 times that of Earth. Asteroids therefore cannot enter
Question # 1: Part A How many electrons and protons in an atom of vanadium? Answer # 1: Atomic number = number of protons = 23 Mass number = number of protons + neutrons Mass number = 51 g/mole Number of neutrons = 51-23 Number of Neutrons = 28 Number of electrons = atomic number = 23 Question # 1: Part B Explain in 2 or 3 sentences how the atomic weight is what is reported. Answer # 1: Atomic weight or atomic mass is basically the average mass of atoms of an element. Atomic mass is calculated by using the naturally occurring relative abundance of isotopes. Atomic weight determines the size of the atom.
On the first ring there will be 2 electrons and on the second ring there is 8 electrons. That gives them a total of 10 electrons. Along with atomic number, protons, and electrons there is a atomic mass which is 20.1797. Neon was discovered by Sir William Ramsay, a Scottish chemist, and Morris M. Travers, an English chemist, shortly after their discovery of Krypton. Like krypton, neon was discovered through the study of liquefied air.
This atom contains 30 protons and 30 electrons. It can be found in the 4th period and has 4 energy levels. In the first energy level there are 2 electrons. In the second there are 8 electrons. In the third, there are 18 electrons and in the fourth level, also known as the Valence shell has 2 valence electrons.
Chemical Properties: Reaction with air: - When plutonium is exposed to air it begins to oxidise, it forms a yellowish-brown outer coat and begins to tarnish. Soluble in: - Hydrochloric acid Insoluble in: - Nitric acid - Concentrated hydrogen sulfide The Critical Mass: - Around 300 grams which is only about a third of that of Uranium 235 Allotopic Structures: - Plutonium exhibits six forms of crystalline structures. The only form that exists at room temperature is the alpha structure. It has the highest electrical resistivity of any metallic
The gold sank into the middle. A mantle was created from gold, protecting a core of diamonds, and forcing a small metallic field. The surface grew hotter, while the core grew cooler. Two tectonic plates formed on the planet, just enough to create the volcanoes needed for food and drink. The comets that formed Feuer Leava contained significantly large amounts of amino acids, the buildings blocks of life.
It has a halo, however that you can’t really see it. It has over 200 billion stars it’s quite dusty and gassy. It is spiral galaxy. 2. How are galaxies organized and distributed within the universe?
The constellation I have chosen is Aquila. Aquila has 10 main stars, and 65 Flamsteed stars. It 's known for the being in the shape of an eagle, and the brightest star is Altair, which is two times more massive than the sun. Altair will only live 2 billion years, compared to the Sun 's 10 billion years. The reason I found this constellation interesting is because the Pioneer 11 spacecraft has been sent towards Lambda Aquilae, which is 125 light years away!
