Answer/Explanation: As mentioned above, the characteristic chemical property of a metal atom is to lose one or more of its electrons to form a positive ion. However, certain metals lose electrons much more readily than others. In particular, cesium (Cs) can give up its valence electron more easily than can lithium (Li).

First, we calculate for the total volume of aluminum. The
volume of a cube is:
V = s * s * s = s^3
V = (2.70 cm)^3
V = 19.683 cm^3
Assuming atmospheric temperature, the density of aluminum is
about 2.70 g / cm^3. Therefore the equivalent mass of aluminum is:
m = 19.683 cm^3 * 2.70 g / cm^3
m = 53.1441 g
The molar mass of aluminum is 27 g / mol. Therefore the
number of moles is:
n = 53.1441 g / (27 g / mol)
n = 1.9683 mol
Given the number of moles, we can calculate for the number of
atoms using Avogadro’s number.
atoms = 1.9683 mol * (6.022 * 10^23 atoms / mol)
