2) Calculate the density of a rod of metal (in g/cm²) with a mass of 194.41g, a diameter of 2.40 cm and a height of 7.45 cm. Volume cylinder = 1 h/Remember the radius is half the length
of the diameter.
Volume =
Density =
3) Calculate the percent error for your density in question (2), if the accepted density of this
metal is 9.23 g/cm
Percent error = | accepted density - experimental density | x 100
accepted density

Which element in the third period would you expect to have the larger atomic radius, sodium (na) or sulfur (s)? a. sodium, because it has a higher effective nuclear charge attracting electrons in fewer energy levels. b. sodium, because it has fewer protons attracting electrons in the same energy levels. c. sulfur, because it has more protons attracting electrons in more energy levels. d. sulfur, because it has a higher effective nuclear charge attracting electrons in the same energy levels.

Which of these conditions most likely produces an unstable isotope?
