To determine which element is most likely a nonmetal based on properties, we would typically look for characteristics such as high electronegativity, poor conductivity, low density, and the ability to form anions or covalent compounds.
Since I don't have access to the specific properties listed in the chart you're referencing, I can't identify which element is a nonmetal specifically. However, if you have the properties described for each element, feel free to share them and I can help analyze them to identify the likely nonmetal!
