The Nobel Prize in Physics 1968 was awarded to Luis Alvarez "for his decisive contributions to elementary particle physics‚ in particular the discovery of a large number of resonance states‚ made possible through his development of the technique of using hydrogen bubble chamber and data analysis". Alvarez’s colleagues sometimes called him the "prize wild idea man" because of the huge range of his activities. He did all kinds of research into the atomic nucleus‚ light‚ electrons‚ radar‚ and so

Disappearing Spoon - Chapter 1: Geography is Destiny - Chapter 1 of The Disappearing Spoon discusses the importance of an element’s location on the periodic table based on the atomic number and type of material‚ and how this specific area determines its atomic “identity” and relation to other elements. This also includes the reactivity of elements based on their electron configurations. This relates directly to what we have studied in Chapter 5 of our textbook. One example from The Disappearing

Atomic radius is defined as the distance from the outermost ring‚ referred to the valence shell‚ to the centre of the atom. On the periodic table‚ going across from left to right‚ the atom’s relative size decreases. However‚ going down the group‚ the atomic radius increases in size. From left to right there is an increase of positive charges in the neutron and the electrons. Due to the increase of the number of positive charges‚ the electron’s attractive force becomes stronger‚ thus (the electrons)

Quite a few scientists have helped to create and extend ideas on what an atom is and what its components are. One of these discoverers‚ John Dalton‚ developed the first modern atomic theory. Although much of his theory is still true today‚ one point was disproved by Ernest Rutherford. Dalton’s atomic theory had several parts to it. He believed atoms were indivisible‚ or impossible to break down into smaller particles. Also‚ he said elements are all consisted of atoms and that the atoms of

Neon By: Ariana Neon was discovered by Morris Traver‚ and William Ramsay in 1898. Neon is a gas that produces a colored glow when excited by electricity passing through a glass tube in which the glass is confined. But you may wonder how are these neon lights even made? Well‚ the Neons gas is inserted into glass tubing using a thin pipe then the pipe is quickly removed‚ and the glass is fused at the end. The neon tube produces the light when an electrical current bombards the gas atoms with electrons
