Trends of the Periodic Table of Elements

Trends of the blockic Table of Elements Introduction The objective of this experiment was to establish trends in the goalic Table of Elements, involving the characteristics of elements in the same group and/or period. In Part 1, the dissolve point trends of alloylic elements in crowd 1, dot 3, end 4, Period 5, and Period 6 were observed, use the grab Elements website (http://www.webelements.com/), and then were graphed (by each throng or Period privately) to unwrap the trends. Trends were observed in all graphs, and the warming points were tie in to multiple variables, such as electron configurations, atomic charge, shielding, nuclear radii, and cohesion energies. In Part 2, company two nitrates were abstruse with different solutions, and were observed for indications of chemical reactions (precipitate formation and solubility) that formed occasional(a) trends. In Part 3, six specific metals were reacted, in individual prove tubes, with hydrochloric ac id and a variety of different metal ion solutions, in order to find if a reaction of metal faulting happened. The observations noted formed a trend of increase responsiveness among the six metals.

Experimental In Part 1 of the experiment, the nett Elements website was used to make 5 scatter plot graphs that showed the warming points at certain atomic numbers, from the information provided by the cyclicity of melting points section of the website. In the graphs, the melting point (in degrees Kelvin, K) was invent along the y-axis, and the atomic number along the x-axis; all graphs were melting Point vs. Atomic Number graphs. graph 1 contained Group 1 elements: Li, Na, K, Rb, Cs, and Fr. graphical record 2 contained Per! iod 3 elements: Na, Mg, and Al. Graph 3 contained Period 4 elements: K, Ca, Sc, Ti, V, Cr, Mn, Fe, Co, Ni, Cu, and Zn. Graph 4 contained Period 5 elements: Rb, Sr, Y, Zr, Nb, Mo, Tc, Ru, Rh, Pd, Ag, and Cd. And Graph 5 contained Period 6 elements: Cs, Ba, Lu, Hf, Ta, W, Re, Os, Ir, Pt, Au, and Hg (1)....If you want to get a full essay, order it on our website: OrderEssay.net
