Density of Metals Problem: How does the mass and volume help determine the density of known metal samples? Hypothesis: When comparing the density of Zn(zinc) and Cu(copper)‚ you will find that Copper is more dense than Zinc. You can test this out by using the density formula D=m/v. Materials: * 2 metals (options: zn‚ al‚ or cu) * 3 samples of each metal (small‚ medium‚ and large) * Scale/Balance * Calculator * Water * Graduated Cylinder Safety: * Be prepared for your

Experiments with Metals and Ions of Metals Introduction Metals are similar in their physical properties in general‚ but they are not identical. Most of the metals are solids; few of them are liquids‚ such as mercury and cesium. Density of metals is not similar also. For example‚ sodium has density of 0.97g/cm3 while lead has density of 11.4g/cm3. Melting point of sodium is 98.0oC while for lead it is 327.6oC. Metals have the capability to lose electrons when they react with non-metals such as

Metals and Halogens reactions Elements such as fluorine‚ chlorine‚ bromine‚ iodine‚ and astatine belong to Group 7‚ Halogens. At room temperature‚ fluorine is a yellow gas‚ chlorine is a pale green gas‚ bromine is a red liquid‚ and iodine is a purple solid. Astatine is a radioactive element‚ therefore it exists only in small amounts. All the halogens exist in diatomic molecules. They have high ionization energies and are the most electronegative elements. Their electron configuration ns2 np5 make
