The Periodic Properties of Atoms The Periodic Table: In the 1870’s‚ the Russian chemist Mendeleev developed the periodic table‚ based upon the relationship between the atomic weights of the elements and their chemical properties. As one ascends from lightest to heaviest elements‚ there is a periodic recurrence of chemical properties. For example‚ the elements with atomic numbers 2‚ 10‚ 18‚ 36‚ 54‚ and 86 all are chemically inert (the noble gases)‚ while those with atomic numbers one greater 3‚ 11

According to the Leibniz’s princciple of the indiscernibility of identicals‚ the philosopher Gottffried Leibniz argues that if 1 and 2 are identical then they have exactly the same property. It means that mind can never be physical object‚ which is a fact that could be derived here. Additionally the arugument is that no machine or computer in the world can have conscious‚ i.e.‚ feel of pain‚ feeling of happiness‚ sad etc.‚ But by incorporating some additional algorithms and hardwares these computer

Department of Chemistry [Colligative Properties & Osmotic Pressure] Purpose : The experiment this week had two different purposes. The first is to teach us about freezing points. This lab was designed to show us the freezing point of a pure solvent‚ in comparison to a solvent in a solution with a non-volatile solute. The second goal of the experiment is to teach students about osmosis. In the experiment‚ we got to observe osmosis as well as understand dialysis

Lab 4: Physical & Chemical Properties Purpose: The purpose of this lab is to distinguish if different substances react to heat or cold and if a solution is added to it during the experiment will it change the substance or leave it the same. Throughout the different tests each substance is put through a series of tests to determine if it changes in any way in regards to color‚ odor‚ or consistency from the start of the experiment. The results will be documented in table 1. Data Table 1: Solubility
