Proton Wira

is composed of protons and neutrons. These two particle are called nucleons, and can be found in the nucleus. The protons are all positively charged and repel each other, this is called the electromagnetic force. This pushes the protons apart but they are held together by another outside force. This is called the strong nuclear force. This force holds then nucleons together in the nucleus. Bismuth with a proton number of 83 is the stable nuclei with the highest number of protons. All nuclei with

Introductory Chemistry: Basic Chemistry Part 1: 1. (a) Matter makes up everything in the universe, consisting of particles, the three states of matter include; • Solids - Particles within a solid vibrate slightly due to having the least kinetic energy, this forms an attraction between the atoms so they remain closely packed together in a regular formation. • Liquids – Particles within a liquid have slightly more kinetic energy therefore can move past one another. They are somewhat more spaced apart

Electricity is a vast, widely explored subject that humans largely take for granted. This vastness has sparked a large amount of curiosity in the subject. The curiosity has, in turn, sparked a large amount of exploration into the mysterious subject. And because of this, there is an equally vast amount of ways to learn about it, expanding at the same rate of our knowledge on the subject. One way to learn about this amazing thing is through play. (Squishy Circuits) No matter how dangerous it is, there

2000 years ago the Greek philosopher Democritus came up with the idea that if he cut an object in half, for example a rock, that he could eventually cut it until he reached a tiny piece that could no longer be cut or divided. Democritus named this unbreakable piece ‘atomos’ which in greek meant ‘indivisible/ uncuttable’. However this idea was rejected in favour of another philosopher, Aristotle, whose theory was that all matter was made up of 4 elements, fire, water, air and earth. For thousands

12/12/2016 Utilities in the US and GIS GIS is critical to the utilities industry in the US. It allows them to perform mundane tasks that they are required to perform with new levels of ROI (return on investment), safety, and man-hour efficiency. It also allows them to save the taxpayer a substantial sum of money yearly, and also the ability to remain profitable while billing for less. In this paper, I will first discuss some of the basic ways that the utilities industry in the US is using GIS

(H3O+), when dissolved in water, and a base, the complementaries of acids, as a substance that produces hydroxide ions (OH-) in water. Definitions from other scientists such as Brønsted-Lowry expanded on this range and defined acids as proton donors and bases as proton acceptors, with the most expansive definition coming from G.N. Lewis, who defined acids as electron pair

CH 220C – Organic Chemistry Lab Experiment 13: Electrophilic Aromatic Substitution: Nitration of Bromobenzene and Relative Rates of Reaction Rodan Devega Introduction Electrophilic aromatic substitution (EAS) reactions involve the replacement of a hydrogen atom bonded to an aromatic compound by an electrophile. The rate and direction of the EAS reaction depends on the functional groups present on the aromatic compound. The purpose of this experiment was to synthesize bromonitrobenzene by reacting

because in an atom, the number of electrons matches the number of protons. In spite of this, one element is distinct from another element if the number of protons are different. 30. The atoms that constitute your body are mostly empty space, and structures such as the chair you’re sitting on are composed of atoms that are also mostly empty space. So why don’t you fall through the chair? It starts with subatomic particles, such as protons and electrons, produce electrical fields. These relating electrical

matter. The atom is made up of three subatomic particles protons (p+) , neutrons and electrons ( e-). Protons have a positive charge and can be found in the nucleus along with the neutrons who have no charge. Protons, along with electrons, tell you the atomic number of any given element. A positron is the opposite of an electron and contains the same mass and spin of an electron but they have a positive charge. The sum of the number of protons and neutrons equals the mass number. The mass number connects

name from its main source, potash salt. Potassium is number 19 on the periodic table, with the letter K as its chemical symbol. The K comes from the latin word “kalium” meaning potash. Potassium has 19 protons, 20 neutrons, and 19 electrons. Its atomic number is 19, because it has 19 protons, and its atomic mass is 39.0983. Potassium is a metal, categorized underneath the group alkali metals, this means it is a soft silvery metal. Potassium was discovered in 1807, in england. It was discovered
