Atoms: They’re the smallest object that create the properties of an element. Comprised of the subatomic particles: electrons, protons and neutrons. For which the Nucleus contains the Protons and Neutrons, while electrons orbit around the nucleus. The atom is a fundamental piece of matter. Atoms are the building blocks of matter and matter builds up the Universe. A Valence Electron is an electron, which is a subatomic particle of an atom. Valence electrons are located in the outermost shell of…

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 connection between the protons and neutrons in the nucleus. Nuclear stability is the stability of the nucleus which,…

How threatening it might sound, nuclear medicine is a very common type of treatment, as “On average, one in every two Australians can expect at some stage of his or her life to undergo a nuclear medicine procedure,” (Australian Nuclear Science and Technology Organization). It may come as a surprise, but these include Nuclear Imaging such as MRI (Magnetic Resonance Imaging), Pet scans, CT (Computerized Tomography) CAT (Computerized Axial Tomography). And no it is not A green liquid in a capsule…

The Atomic Theory states that all matter is composed of discrete units called atoms. The Atomic Theory started in about 400 BCE with a scientist by the name of Democritus. Democritus proposed the idea of the existence of an ultimate particle. He called this particle atomos when he was describing it, because the particle was too small to cut. Next, we get to Leucippus. Leucippus was the man who founded atomism, which is a theoretical approach that states nature consists of two principles, which…

History of the Theory of Atoms Before the age of modern technology, theories of the atom were still created. Most notably was Democritus who was thought of as being the start of modern science when he first came up with the idea of the atom. It was not until J.J. Thomson changed the way atoms were understood with the discovery of the electron. It was not soon after when Ernst Rutherford disproved Thomson’s model with his gold foil experiment. Finally, Niels Bohr built off Rutherford’s gold foil…

and 3 instead of the normal 1. James Chadwick made the most recent major discovery of the atom. In 1932, he discovered the neutron in the atom. James was a collaborator with Ernest Rutherford, and with this discovery it led to the discovery of fission and ultimately the atomic bomb (H). The modern atomic theory is that it has an orbital of electrons with the protons and neutrons within the middle. Typically depicted by the Bohr’s model…

The atomic theory has revolutionized the field of science. The ideas behind it began in the times of Ancient Greece. From there the ideas were put under trial, proven, disproven, and formed into what we now recognize as the atomic theory. Since the beginning of time, people believed that matter was made from a few fundamental building blocks. In ancient times, these fundamental elements were thought of as water, fire, earth, and air. Around 400 BCE, Democritus and Leucippus developed a…

electromagnetic energy called quanta. The electron cloud model and the quantum mechanics model are two different models talking about what the model looks like. They are both based on quantum mechanics. They both also involve a central location of protons and neutrons called the nucleus. But the quantum mechanics shows the electrons orbiting around the nucleus. The electron cloud shows the electrons more spread out like a cloud and they have no definite pattern they spread and move freely, like…

208Pb 82 82 82 82 A atom is the basic unit of an element .it is a form of matter which cannot be broken down any further .an atom consist of sub atomic particles which are protons, neutrons and electrons .I will be looking at specifically the atom lead. Every element in the Periodic Table has been given a letter symbol , the symbol for lead is Pb.i will now describe the sub atomic particle in lead .protons are in the nucleus of the…

An Isotope is an atom of an element which has a different number of neutrons and different mass number but the same proton number. The isotope that will be focused in the essay is carbon 14 isotope. Carbon is found in all living things and is the building block for organic material, there is carbon 12, 13 and 14 and they all have different properties. This isotope was discovered on February 27, 1940 by Martin Karmen and Sam Ruben and is the most radioactive out of all carbon isotopes. The…
