Question

1. directions select the correct answer periods are horizontal rows of the periodic table that exhibit trends as you move from left to right. the table below has several columns left out for simplicity which element has the lowest ionization energy, based on its position in the periodic table? select the correct answer.

Explanation:

Ionization energy increases from left - to - right across a period in the periodic table. Among the elements shown, Li is on the far left side of the period it is in. So it has the lowest ionization energy among them as it is easier to remove an electron from it compared to elements on its right in the same period.

Answer:

Li
