Because energy is required to remove an electron from a neutral atom, it increases up and right. It increases up a group and to the right a period because in small atoms, electrons are closer to the nucleus were the attraction is stronger. So these are harder to remove. But in larger atoms, electrons are further from the nucleus and are easier to remove.
I learned this in my Chemistry class this year. Hope this helps anyone.

What is the trend in period 2 ionization energy across the elements?
The trend in period 2 ionization energy across the elements increases from left to right.
What is the general trend of ionization energy as you go across the periodic table?
Across a period, first ionization energy increases. However, when going down a group, first ionization energy generally decreases. As you go down a group, atoms hove more total electrons so they don't really care that much about their outermost ones.
Why does the ionization energy increase across a period?
The ionization energy increases across a period because as you move from left to right, the number of protons in the nucleus increases, leading to a stronger attraction between the nucleus and the electrons. This makes it harder to remove an electron, resulting in higher ionization energy.
What trend in ionization energy occurs going across a period on the periodic table and why?
Ionization energy generally increases across a period from left to right on the periodic table. This trend occurs because as you move across a period, the number of protons in the nucleus increases, resulting in a greater nuclear charge. This stronger attraction between the nucleus and the outer electrons requires more energy to remove an electron, thus increasing the ionization energy.
Why does the first ionization energy generally increase across a period for the main group elements?
The first ionization energy generally increases across a period for main group elements because as you move from left to right across a period, the effective nuclear charge increases, making it harder to remove an electron from the outer shell. This results in a higher energy requirement to remove an electron, leading to an increase in ionization energy.
What happens to the first ionization energy of the elements as a period is crossed?
Moving from left to right across a period, the first ionization energy increases because it becomes increasingly difficult to remove an electron.
What is the trend in period 2 ionization energy across the elements?
The trend in period 2 ionization energy across the elements increases from left to right.
Which element in the fifth period has the highest ionization energy?
The element in the fifth period with the highest ionization energy is xenon. Ionization energy generally increases across a period from left to right, so xenon, being on the far right of the period, has the highest ionization energy.
How does ionization energy of elements in the same period change?
Ionization energy increases as you go across a period, but as you go down a group it decreases.
What is the general trend of ionization energy as you go across the periodic table?
Across a period, first ionization energy increases. However, when going down a group, first ionization energy generally decreases. As you go down a group, atoms hove more total electrons so they don't really care that much about their outermost ones.
Is it ionization energy is a periodic property?
Ionization energy generally increases across a period as a result of a higher nuclear charge, however there are some exceptions such as Boron which has a lower ionization energy than Beryllium (because it is in a P orbital), and Oxygen which has a lower ionization energy than nitrogen (Because ionization decreases the electron electron repulsion in its orbitals).
Why does the ionization energy increase across a period?
The ionization energy increases across a period because as you move from left to right, the number of protons in the nucleus increases, leading to a stronger attraction between the nucleus and the electrons. This makes it harder to remove an electron, resulting in higher ionization energy.
What is the general trend in ionization energy?
increases from left to right across a period.
What trend in ionization energy occurs across a period on the periodic table and why?
The ionisation energy increases across a period. Across a period, nuclear charge increases. The tendency to loose electron decreases.
Does arsenic have the highest ionization energy?
No, arsenic does not have the highest ionization energy. Ionization energy generally increases as you move across a period in the periodic table from left to right. In the case of arsenic, it is found in the 3rd period, so elements to the right of it, such as bromine, have higher ionization energies.
What trend in ionization energy occurs going across a period on the periodic table and why?
Ionization energy generally increases across a period from left to right on the periodic table. This trend occurs because as you move across a period, the number of protons in the nucleus increases, resulting in a greater nuclear charge. This stronger attraction between the nucleus and the outer electrons requires more energy to remove an electron, thus increasing the ionization energy.
What has the greatest first ionization energy Li Be B or C?
It's carbon. The trend for 1st ionization energy is that it increases as you move left-to-right across a period. As you move in that direction across period 2, ionization energy increases, and since carbon is the most to the right, it has the highest 1st I.E.
