Paragraph 1: Quartz‚ also known as SiO2‚ has a tetrahedral structure that is similar to FePO4 under normal circumstances. However‚ there is the presence of a few differences. For FePO4‚ it’s a cation is a transition metal‚ unlike silicon which is a metalloid. This study summarises the changes in structure of FePO4 over a range of temperatures. Quartz belong to the trigonal crystal system‚ but not considered to be part of the rhombohedral lattice system. Both α- quartz and β-quartz are chiral crystal

DOWNLOADED FROM WWW.STUDIESTODAY.COM DOWNLOADED FROM WWW.STUDIESTODAY.COM d – AND f – BLOCK ELEMENTS Electronic Configuration of Transition Metal/Ions The d-block element is called transition metal if it has partly filled d-orbitals in the ground state as well as in its oxidised state. The general electronic configuration of transition metal is (n–1) d1–10ns1–2. Exceptions in electronic configuration are due to (a) very little engery difference between (n–1) d and ns orbitals and (b) extra stability

I am going to discuss the modern concept of the atom. I am going to give a brief history of the atomic model including Thomson’s atom‚ Rutherford’s atom‚ Bohr’s atom‚ and Schrödinger’s atom. I am going to include a diagram for each of these models. In 1897 physicist‚ J.J. Thomson‚ shortly after discovering electrons‚ proposed his Plum-Pudding model of the atom. He based this model on the two facts that he knew at the time: 1. atoms contain small negatively charged particles called electrons

In this lab‚ each person in the group will have two pennies. Galvanization of a penny will create a brass penny. Galvanizing the penny in sodium hydroxide with zinc causes the penny to turn from bronze to silver. Once the penny is fully galvanized you will burn the penny and spray it off and then it will turn gold. There will be a weight change also a mass change. Observing the penny to see it turn from bronze to silver to gold. Literature review Covalent bonding is a bond when atoms share pairs

The name silver is derived from the old Anglo-Saxon word ‘seolfor’‚ and the symbol (Ag) comes from the Latin name Argentum. From B.C times to present‚ the way the element silver is prepared‚ used and priced has slowly changed and evolved. Although these things change over the course of history‚ the chemical and physical properties of silver and any other element do not. Silver was not only used in Ancient Times‚ but throughout the Bible as well. Considered a precious metal since Ancient times‚ the
