The discovery of the nucleus helped him find that atoms are mostly a bunch of empty space. He measured the nucleus by measuring the angles of scattering and using mathematical modelling found that the nucleus is less than 10-14m in diameter. Most important, he discovered the proton because of that. He came to the conclusion that, “The alpha particles were being scattered by a large amount of positive charge concentrated in a very small space at the center of the gold atom” (Tretkoff, Ernie). This discovery is so important because protons are what define what element an atom is.
Halogens are group 17. Halogens are highly reactive in elemental form. Even though this group only needs one electron in its outer level, it has seven electrons. When halogens are in gas form they are diatomic molecules. Diatomic molecules are two atoms in the same covalent bonds.
Although Venus has a central core, rocky mantle, and solid crust composition similar to earth, the environment within its atmosphere other than its composition is extravagantly different. Venus is 108.2 million kilometers away from the sun and the second closest planet to the sun. The atmosphere of Venus creates a greenhouse effect trapping all the heat in. This leads to Venus having an average surface temperature of 462 degrees Celsius. Crowning it the planet with the hottest surface temperature in our galaxy.
The protons and neutrons together form the nucleus. Lithium has 3 protons and usually 4 neutrons since its atomic weight is 6.9 according to the periodic table. The atomic weight is 6.9 because most isotopes in natural Lithium (isotopes are defined as atoms with “the same number of protons but different number of neutrons” (1) ) have 4 neutrons and fewer have 3 neutrons. The atoms of the isotopes of Lithium behave almost exactly the same way when doing chemistry, since the atoms electrons only care about the charge of the nucleus. The arrangement of electrons in an atom is known as its electronic configuration.
Nobody is quite sure exactly what it is, except that it’s a fundamental property of matter, existing in 2 opposite polarities called positive and negative. Protons, 1 of 2 particles in atomic nuclei, are positive, while neutrons have no charge. Orbiting around the nucleus are electrons, the same number as protons inside the nucleus. Although electrons have 1,836 times less mass than protons, an electron has an equal (but opposite) charge (positive). Because they’re light and positioned outside the nucleus, electrons are much more easily dislodged from atoms than protons, so they’re the crucial carriers of electric charge.
It also has some unique chemical abilities and/or properties when it is with other elements from the periodic table. Plutonium is chemically reactive, it can form compounds with carbon, nitrogen, silicon, and the halogens from the periodic table ("Plutonium Element Facts."). Thanks to this information, it has helped our society understand plutonium’s fascinating
NUCLEAR ENERGY Nuclear energy is the energy in the nucleus of an atom. Atoms are the smallest particles that can break a material. Nuclear energy can be used to produce electricity. This energy can be obtained in two ways: nuclear fusion and nuclear fission. In nuclear fusion, energy is released when atoms are combined or fused together to form a larger atom.
The gas is placed in glass tubes and an electric current is sent through the gas. When that occurs, neon enters a plasma state and glows orange-red. Neon is the tenth element of the periodic table and the second of the noble gases. The element is incredibly non-reactive because of its electron configuration. They use this noble gas for Neon signs, TV tubes, Cryogenics, and Lasers.
Ytterbium is a rare earth metal, one of the elements found in Row 6 of the periodic table. It has an atomic number of 70, an atomic mass of 173.04, and a chemical symbol of Yb. Ytterbium is a typical metal that is both ductile and malleable. It has a melting point of 1,515°F (824°C), a boiling point of 2,600°F (1,427°C), and a density of 7.01 grams per cubic centimeter. Ytterbium is a relatively reactive element that is usually stored in sealed containers to prevent its reacting with oxygen of the air.
Big Bang Theory The Big Bang Theory, It is very mysterious yet ominous when the universe ends with one big bang (emphasis added). There are many people like tribal, philosopher, religious thinkers, and scientists have many questions that many of us are pondering about the universe. Through scientific research, it has given us several viewpoints and has brought to us a thorough explanation of what truly happened in terms of studying the universe and how they come to part. Around 13.7 billion years ago, our universe began as a singularity because all of the matter and energy is compacted into one core. With that being said, the big bang theory well supports Einstein’s theory of general relativity which “determines that the laws of physics
