Which value represents the first ionization energy of a nonmetal?
497.9kJ, 577.4kJ, 811.7kJ, or 1000.kJ ?
I think the answer is 1000. kJ, since it is the highest amount. Am I correct? My reasoning is that nonmetals have higher ionization energies than metals.
Your reasoning is partially correct. Nonmetals generally have higher ionization energies compared to metals. However, the answer is not necessarily the highest amount provided. In this case, the correct answer would be 811.7 kJ because it is the closest value to the average first ionization energy of nonmetals.
You are correct that nonmetals generally have higher ionization energies than metals. However, to determine which value represents the first ionization energy of a nonmetal, we need to consider the specific values given: 497.9 kJ, 577.4 kJ, 811.7 kJ, and 1000 kJ.
The ionization energy is the energy required to remove one electron from an atom in its gaseous state. Since nonmetals tend to have a high affinity for their electrons, it takes more energy to remove an electron from a nonmetal atom compared to a metal atom.
In this case, we see that the highest value given is 1000 kJ. However, this does not necessarily mean that it represents the first ionization energy of a nonmetal. To determine the correct answer, we need to consult a reference source such as a periodic table or a reliable chemistry textbook.
On the periodic table, you will find each element's ionization energy listed as a numerical value. Look for the ionization energy of a nonmetal within the given options: 497.9 kJ, 577.4 kJ, 811.7 kJ, or 1000 kJ. The correct value will match the ionization energy of a known nonmetal element.
Therefore, I recommend consulting a reliable source, such as a periodic table, to determine the exact value that represents the first ionization energy of a nonmetal.
