Answer 1

For Question 1, to determine which element is most likely a nonmetal, you would typically look for properties common to nonmetals such as high electronegativity, low density, and poor conductivity. However, without the specific properties listed in the chart, I can't provide the exact answer. Generally, nonmetals tend to be characterized by their insulating properties and, in some cases, their ability to form anions or covalent bonds.

For Question 2, to model aluminum sulfate, which has the formula Al2(SO4)3, we need to break down the components:

• There are 2 aluminum (Al) atoms.
• There are 3 sulfate (SO4) groups, and each sulfate has 1 sulfur (S) and 4 oxygen (O) atoms. Thus, this means there are 3 sulfur atoms and 12 oxygen atoms in total.

Based on this information, the correct combination of beads would be:

• 2 blue (for 2 aluminum atoms)
• 3 yellow (for 3 sulfur atoms)
• 12 green (for 12 oxygen atoms)

So the answer is 2 blue, 3 yellow, and 12 green.
