Question

Consider atoms of oxygen and fluorine. Which atom will be the least likely to lose an electron to form an ion and why?

Answer 1

Answer: Fluorine

Step-by-step explanation:

Fluorine is least likely to lose an electron to form an ion as it needs only 1 electron to complete its shell compared to Oxygen which needs 2.

Answer 2

flourine

Step-by-step explanation:

Flourine will be the least likely to lose an electron because its ionization energy is higher than oxygen's. Ionization energy is an atoms ability to lose electrons, and it increases up the periods, and across the groups to the right.
