Which of the below is true about ion formation?
when an atom loses an electron, it becomes smaller.
When an atom gains an electron it becomes smaller.
When an atom loses an electron, it becomes larger.
What is the primary factor that causes the atomic radius to increase as you move down in the periodic table?
Increase in atomic mass
Increase in the number of protons
Increase in the number of electron shells
Increase in electron affinity
How does the ionization energy change as the atomic number increases across Period 2?
The ionization energy generally increases due to increasing nuclear charge.
The ionization energy generally decreases due to increasing atomic radius.
The ionization energy remains constant across the period.
The ionization energy decreases and then increases across the period.
What is the primary reason for the decrease in ionization energy as you move down a group in the periodic table?
Because the atomic radius increases.
Due to stronger nuclear attraction.
Since outer electrons are more tightly bound to the nucleus.
As outer electrons are located closer to the nucleus.
