Question

1. refer to the handbook of chemistry and physics, the elements, to research the density, melting point, and boiling point for the following elements.

name density (g*cm^-3) mp (°c) bp (°c)
cobalt
magnesium
manganese
silicon
zinc

1. (optional) go online to wikipedia at www.wikipedia.org to research the density, melting point, and boiling point for the following elements.

name density (g*cm^-3) mp (°c) bp (°c)
cobalt
magnesium
manganese
silicon
zinc

Explanation:

Step1: Refer to reliable sources

Refer to the Handbook of Chemistry and Physics or Wikipedia as instructed.

Step2: Look up element properties

Find density, melting - point (mp) and boiling - point (bp) for each element.

Name	Density ($g\cdot cm^{-3}$)	mp ($^{\circ}C$)	bp ($^{\circ}C$)
Magnesium	1.74	648.8	1090
Manganese	7.47	1246	2061
Silicon	2.33	1414	2355
Zinc	7.14	419.53	907
