Helium

between the types there are similarities. The terrestrial planets have rocky surfaces and are similar in size, density, and radius. They also all have a similar core that is made out of mostly iron. The Jovian planets are composed of mostly hydrogen and helium. They also all have some type of water, usually as water vapor. When it comes to magnetic fields, all of the planets have one except for Venus and Mars. They do have some type of magnetic force, but they are not the same as they are for…

When a star is born it can take one of two paths. It can either take the path of a high mass star or the path of a low mass star. A high mass star will be between 10-50 solar mass and a low mass star will be between .8-10 solar masses. One solar mass is equal to M⊙ = (1.989±0.004) x 1030 kg, which is A LOT. Either path it takes, the one of a high mass or low mass star it will live about 90% of it’s lifetime in its main sequence. Once achieving nuclear fusion the star slowly contracts over…

element with the highest boiling point is Tungsten at 3143 Celsius, and the element with the lowest freezing point is Helium at -268.93 Celsius. They can look different from each other, and one could see this by looking all around them. Most of the elements that you see occur naturally, but some are manmade. Polonium and plutonium are examples of manmade elements. Elements like carbon, helium and nitrogen are one the most common in nature. All matter is theorized to come from the Big Bang,…

particles have 2 protons and 2 neutrons which are in a helium nucleus. As the alpha particles emit the helium nucleus the nucleus gives away the two protons and two neutrons. As a result of this the mass number will reduce by 4 and the atomic number will result in reducing by 2. This is known as alpha decay. One source of alpha radiation could be plutonium 239. The alpha particles have many characteristics. First of all the alpha radiation has a helium nucleus. Also the penetrating power of…

produces its energy through a process known as nuclear fusion. Nuclear fusion is when two atoms combine to form a single atom and a high amount of energy is released. In the Sun, fusion happens with mostly hydrogen atoms, which combine to form a helium atom. Two helium atoms can later combine through fusion and create a carbon atom. Like stated before, this process happens only in the core of the sun. Every second, the sun burns around 600 million tons of hydrogen atoms to keep it going. Because…

diameter of Earth. The average density of the sun is 1.408 g/cm3, which is only a quarter of the density on Earth.The temperature of the sun is averaged around 5 million degrees celsius. 73% of the Sun is made of Hydrogen and 25% of the Sun is made of Helium. The rest of the sun is made up of other elements, such as carbon and iron.…

5 times the Sun, the temperature is approximately 17,000 F (9,500C), the luminosity is about 40 times the Sun’s size, and the star type is is a white main sequence star, so it is in A class. Since it is a main sequence star, it fuses hydrogen into helium in its core, The Vega star is also known as the Alpha Lyrae and is in the Lyra constellation. It is a blur to white star and has a radius of 1.1 million miles, 2.5 times larger than the sun. The Vega star is…

imagined of two types of particles: protons and electrons. The problem with thinking in these terms was that the atomic mass measurements were not matching up with the atomic number, or protons in the nucleus of an atom. An example of this is the helium atom who has the atomic mass of 4, but a positive charge of two and negative charge of two. Positive charges have mass, however, electrons have very little, which made it problematic to explain the reasoning behind the atomic mass and atomic…

that the person is. Darrow's class, the Red class, is considered to be the lowest class in the Solar System, as the Red's jobs are to mine Helium-3, which is a valuable resource on Mars. Darrow, like many other Reds, is driven by the Laurel. The Laurel is a reward given to the family that mines the most Helium-3. Despite his life-risking efforts to gather more Helium, his clan doesn't win the Laurel. When Darrow loses the Laurel for his family, him and his wife Eo, to rebel…

to a certain point it would be around 1 million of earths mass to be equivalent of the sun. There very little that could be more powerful as the sun. It contains two main things that produce heat as it does today. Those two things are hydrogen and helium. The temperature it normally stays at is around 15 million degrees celsius. Which is enough heat to reach to are planet earth this day. The sun tends to be a bomb with this much material packed into one star. But yet gravity keeps it together.…
