and electrons. Germanium’s atomic mass is 72.64, this is the amount of mass in each atom that’s in Germanium. The atomic number for Germanium is 32, which represents where the element is placed on the periodic table and the amount of protons/electrons in each atom that’s in the element. The amount of protons in each atom is the same amount of electrons in each atom. Protons are the positive charges and electrons are the negative charges. Germanium has 32 protons in each atom and 32 electrons in…

atomic number is the number of protons in an element. The atomic mass of Neon is 20.180, which when rounded up will become an atomic mass of 20. The state of matter Neon is mainly in is a gaseous state. The full electron configuration of neon is 1s2 2s2 2p6, and the abbreviated electron configuration is [He] 2s2 2p6. The melting point of Neon is at -248.59 degrees Celsius, and the boiling point is at -246.046 degrees Celsius. Neon has a density of 0.0008999 grams per cubic centimeter ("Facts…

1a) Yes, there is a correlation between the structures and the observed volatilities of compounds in Step (1a) and Step (1b). In Step (1a), n-pentane had the highest vapor pressure because the compound evaporated the fastest. N-heptane had the second highest vapor pressure, followed by n-decane with the lowest vapor pressure. The molecular structure correlates with the volatility because of the molecular weight for each compound. N-pentane is the lightest compound, followed by n-heptane and…

electricity to the audience by showing how it affects us, and how we depend on it in everyday life. The passage proceeds to explain atoms and what their relationship to electricity is. It continues to talk about electrons and atoms, and describes how within the atoms are electrons, and when the electrons move between the atoms, a current of electricity is created. A description of an experiment the passage used was describing how the chain was similar to the fire fighter’s bucket brigades in…

in neutron number and therefore atomic weight classify these atoms as isotopes of the element Hydrogen. An ion is an atom with a charge due to changes in the number of electrons (negatively charged particles) in the atom. Ions that have lost electrons have a positive charge, and are called cations. Ions that have gained electrons have a negative charge, and are known as anions. Examples of…

determine what element the atom is, and the number of neutrons influences the atom’s mass. There are also negatively charged particles, called electrons, to counteract the positive charge of the nucleus. These electrons fly around the atom’s empty space, which the atom is mostly made of (Doc. 2). The electrons are in groups called electron clouds, and these electron clouds help the atom bond with other atoms (Doc. 3, OI). These findings that we know today have been contributed to by many…

Chapter 11, “The Chemical Elements”, was of great interest to me. “Chemistry is the study is the study of the composition and structure of matter (anything that has mass) and the chemical reactions by which substances are changed into other substances (James T. Shipman 285).” In this summary paper, I will discuss some of the highlights of the chapter. The way I see it, God is the original/first chemist. He took His own creations (the elements in our Periodic Table) to make provisions for…

Ultrasound has been used for many years to help diagnosis. Ultrasound describes sound frequencies beyond the range of normal human hearing and 20 kilohertz. Ultrasound uses focused low-energy ultrasound waves to visualize the interior of the body in a noninvasive and painless way. Many people are to thanks for the evolution of ultrasound. Dating back to the 1700’s. Lazzaro Spallanzani in 1793 observed that bats function efficiently in the dark, even when blinded, but not if deafened. He…

Atoms are made up of particles called neutrons, protons and electrons. Electrons have a negative electrical charge, protons have a positive electrical charge, and neutrons have no electrical charge. The neutrons and protons group together in the middle part of the atom, which is called the nucleus. An individual atom atoms will have at least as many neutrons as protons and it will have the same amount of electrons and protons. Atoms have a large amount of energy which holds their nuclei together…

I. Purpose: The purpose of this lab is best understood by the principles of static electricity, as two rough objects rub against each other the atoms of those objects touch and pull upon each other sporadically. When this occurs the electrons of those atoms will transfer between these objects and static electricity is generated. This lab is performed to see the role that static electricity has on objects, when determining their charge and how they interact, all seen by a firsthand course of…
