Lesson 3.01: History of the Periodic Table 1. Explain how scientific observations led to the development of‚ and changes to‚ the periodic table. Dmitri Mendeleev- first periodic table‚ organized 63 known elements according to properties‚ organized into rows and columns. He wrote names‚ mass and chemical properties on each. Julius lothar Meyer- independently worked in German ‚ similar to Mendeleev Henry Gwyn Jeffrey’s Moseley: worked with Ernest Rutherford experimented with 38 metals‚ he found that

equilibrium are that the net force acting on the object is zero‚ and the net torque acting on the object is zero. In the experiment done‚ conditions for equilibrium are observed. Equilibrant forces were determined using the force table and component methods. The unknown forces were also determined using the first and second conditions for equilibrium. Another part of the experiment was to locate the center of gravity of a composite body and to determine rotational equilibrium. 2. Theory An object at

The Periodic Table By Eric Scerri 1. I just returned home from being interviewed for a new public television program on the mystery of matter and the search for the elements. It was very gratifying to see how keen the film-makers were on understanding precisely how Mendeleev arrived at his famous first periodic table of 1869. This in turn meant that I had to thoroughly review the literature on this particular historical episode‚ which will form the basis of this blog. 2. The usual version of how

History of Table Tennis February 10‚ 2009 Table tennis‚ also known as ping pong‚ is a sport in which two or four players hit a lightweight‚ hollow ball back and forth with rackets (also known as ’bats’ or ’paddles’). The game takes place on a hard table divided by a net. Players must allow a ball played toward them only one bounce on their side of the table and must return it so that it bounces on the opposite side. Points are scored when a player fails to return the ball within the rules. Play

in the d-block and it is a transition metal. Technetium is in the 7th group in the periodic table because it has 1 electron on its last shell. Also it is in the 5th period in the periodic table because it has 5 shells. Number of energy levels of Technetium is 5. Its electron shells are 2‚8‚18‚14‚1 as it is in the picture. Firstly‚ Russian chemist Dmitri Mendeleev‚ who is the creator of the periodic table‚ predicted Technetium’s existence. He called it eka-manganese because there was a missing element
