(a) Which has the smaller fourth ionization energy, Sn or Sb?

Video transcript

Hello everyone today. We are the following problem. Select the element that has a smaller fourth ionization energy from the following pair silicon or phosphorous. So it's important to note the trend for ionization energy, abbreviated by I C. E. So for our organization energy, it increases as you go from the left side of the periodic table to the right and it decreases as you go down a group. And so based on the positioning of these two elements here, we can note that the ionization energy for silicon is going to be less than the ionization energy for phosphorus, making our correct answer silicon overall, I hope this helped, and until next time.
