Title: Making Predictions using Periodic Table on elements 116,118,119
Post by: jesse.counter on February 21, 2006, 05:08:29 PM

For an assignment i am supposed to predict the density, boiling points and melting points of elements 116,118, and 119. I eneted data into excel and created graphs with a trend line, but i was wondering if anyone would be able to provide any estimations for me.

For example, the 119th element would be an alkali metal . The boiling point appears to decrease as the atomic number increases, but it is hard to estimate. Any help is appreciated

Are you trying to determine the slope (m) of your line concerning boiling point or ?

for the equation y=mx+b

slope or m = y2 - y1
                         x2-x1

I was looking to get an approximation for each value of density, boiling point, and melting point for the elements 116,118 and 119. But i think im satisfied with what i have now
