Ionisation energies GENERALLY increase across a period. As a result, the noble elements (i.e. Group 0 elements) usually have the highest ionisation energies, as they are highly stable.

Which elements has the highest ionization energy?
Helium (He) has the highest ionization energy, then Neon (Ne) Ionization energy increases as you go across a period from left to right. Ionization energy decreases as you go down a group. Therefore, elements in the upper right of the periodic table have the highest 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.
Which element in the fifth period has the highest ionization energy?
xenon increases from left to right across periods (first ionization energy)
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).
How does the first ionization energy change going down and across the periodic table?
In a group the first ionization energy decrease going down.In a period the first ionization energy increase from left to right.
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.
Which elements has the highest ionization energy?
Helium (He) has the highest ionization energy, then Neon (Ne) Ionization energy increases as you go across a period from left to right. Ionization energy decreases as you go down a group. Therefore, elements in the upper right of the periodic table have the highest ionization energy.
What accounts for the general trend in the first ionuization energy of the elements within a period?
As you go from right to left in a period in the periodic table the ionization energy increases. While going from top to bottom in a group in the periodic table the ionization energy decreases .
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 is the trend across a period?
what is the reason for ionization energy across a period
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.
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.
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 is ionization energy and how does it relate to the periodic table?
The ionization energy is the energy needed to extract an electron from an atom.The value of the ionization energy increase from left to right in a period of the periodic table and decrease in a group from the above to down.
Which element in the second period has the greatest ionization energy?
Neon
How does the first ionization energy change going down and across the periodic table?
In a group the first ionization energy decrease going down.In a period the first ionization energy increase from left to right.
