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, extremity 3, flow rate 4, Period 5, and Period 6 were observed, use the take hold of Elements website (http://www.webelements.com/), and then were graphed (by each throng or Period privately) to showing the trends. Trends were observed in all graphs, and the resolve points were tie in to multiple variables, such as electron configurations, thermonuclear charge, shielding, nuclear radii, and cohesion energies. In Part 2, meeting two nitrates were mire 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 quiz tube s, with hydrochloric acid and a variety of different metal ion solutions, in order to find if a reaction of metal switch happened. The observations noted formed a trend of increase responsiveness among the six metals.

Experimental In Part 1 of the experiment, the entanglement Elements website was used to make 5 scatter plot graphs that showed the dissolve points at certain atomic numbers, from the information provided by the periodicity of melting points section of the website. In the graphs, the melting point (in degrees Kelvin, K) was jut out along the y-axis, and the atomic number along the x-axis; all graphs were melting Point vs. Atomic Number graphs. graph 1 contained G roup 1 elements: Li, Na, K, Rb, Cs, and Fr. ! interpret 2 contained Period 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
