Why does the ionization energy increases as you go from left to right across a period?

because the more valence electrons a element has, the more it wants to become a noble gas. The pull is stronger because it is trying to get other electrons.

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.
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 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.
What is the general trend in ionization energy?
increases from left to right across a period.
What trend in ionization energy occurs going 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.
Which element in the fifth period has the highest ionization energy?
xenon increases from left to right across periods (first ionization energy)
What has the highest first ionization energy phosphorous calcium sodium or aluminum?
Phosphorus. Across the period, first ionization energy increases.
As you go from left to right across a period the first ionization energy generally decreases or increases?
increases.
What is the general trend in first ionization energy?
increases from left to right across a period.
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).
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.
How does Ionization Energy behave along the Periodic Table?
Ionization energy increases as we go across a period. Its value decreases as we go down a group.
