Proton

This is Polly proton, Nick neutron, and Ellie electron and they make up an element. Out of all of the 3 siblings , amy atom in one of the smallest particles. Polly Proton was born when Goldstein observed through a cathode ray. A cathode ray was the first device which gave evidence to how amy atom is built/structured. Polly proton and nick neutron make up the nucleus which is the central core of Amy atom. A few years after amy atom was discovered Polly proton was found to be heavier than Ellie electron with mass that was greater by 1840 times.One day a scientist named Dalton discovered the ability to create chemica reactions. He believed that Any atom within the same group of her friends and family are similar and sometimes identical. Thomson was able to discover Ellie electron whom he…

The nuclear model of the atom consists of mostly empty space, the center of the atom is called the nucleus, the nucleus contains the protons, which have a positive electric charge, along with the neutrons, which have a neutral charge and is slightly heavier in mass when compared to a proton. Along the outer rings of the atom the electrons orbit, the electrons have a negative electric charge, as well as the smallest mass out of the three. “The nuclear forces” is a common name used to describe the…

High temperature proton exchange membrane fuel cells (HT-PEMFCs) are a promising clean technology, especially for automobile applications.1 These devices generate electricity from the chemical reactions that occur in the anode side of the cell, using H2 as a fuel and generating heat and water as by-products.2, 3 However, experimental studies using HT-PEMFCs show that degradation of the cell can occur after certain hours of operation (around 500 hours).4 Some of the factors that contribute to the…

Proton radiotherapy is a new type of treatment that is becoming the new standard of approaching a common tumor among children. Support by researchers, there is evidence that proton radiotherapy actually reducing some long-term side effects such as less severe cognitive damage, while maintaining the same hormonal levels as the older form of therapy (photon radiotherapy). One primary difference between the two therapies revolves around the way in which radiation passes through the patient’s…

In our time and age, many inventions depend on the use of static electricity such as printers, photocopiers , pollutant removers and even spray painting. Now imagine how our world would differ if we did not have the implementation of static electricity in inventions such as photo copiers or printers. These simple inventions solve big problems. What is static electricity? How do printers work? Why do we need Printers? What are the advantages and disadvantages of the use of printers? These factors…

Atoms are what make up what we call “matter.” They are the smallest units of a chemical element, and they consist of protons, neutrons, and electrons. These components form an atom’s subatomic particles. Before discussing the copper atom at length, we must first be able to understand the components that comprise an atom. The first of these components that make up an atom is the proton. The proton is a very important part of an atom, because the atomic number of an atom is equivalent to the…

question: what exactly are the properties of copper that give it its properties? An element is a chemical substance in its simplest form. An atom is the basic unit of a chemical element. An atom consists of particles such as electrons, protons, and neutrons. The protons and neutrons of the atom make up its center, called the nucleus, and its electrons surround the nucleus from a certain distance.…

Atoms are the most basic building blocks, everything around us are made out of atoms. Atoms are so small that it can’t be found under the finest microscopes. A tiny spec of dust contains millions of billions of atoms! Even though atoms are tiny, but it actually consist of three different particles: protons, neutrons, and electrons. In every atom, electrons move around the nucleus, the combination of protons and neutrons. The idea of an atom was first discovered by the ancient Greeks, they…

molecules consist of two or more atoms linked together. An atom of the violently active metal sodium (Na) linked to an atom of the poisonous gas chlorine (Cl), for instance, gives one molecule of common salt (NaCl) — an important body ingredient. Structure of the atom: There are two distinct regions to an atom. The first is a dense closely packed nucleus made up of protons and neutrons. Protons are positively charged and neutrons are neutral in charge. Together they make up much of the…

Atomic structure AC1.1 1. Produce a table showing each sub-atomic particle with their relative masses and charges (Bbc.co.uk 2015). Particle Relative Charge Relative Mass Proton +1 1 Neutron 0 1 Electron -1 2. Explain the meaning of the terms, ATOMIC NUMBER and MASS NUMBER of an atom in terms of sub atomic particles. The atomic number refers to the number of protons in an atom, the mass number refers to the number of protons plus the number of neutrons (Bbc.co.uk 2015). 3. A…
