The ionization energy increases because the energy required to remove a valence electron will increase. The atoms want to keep their valence electrons because as you move more towards the right of the Periodic Table towards the noble gases. To write an abbreviation for electron configuration, it requires a noble gas and the valence electron configuration.

∙ 14y agoAs you go down the periodic table the first ionization energy goes down because the electrons become farther and farther from the protons.

What is group trend in the first ionization energies?
Ionization energies decrease moving down a group, because the shielding effect reduces the pull of the nucleus on valence electrons. Making them easier to remove.
Which electrons in the first period have higher ionization energies?
In the first period, the ionization energy increases from left to right across the period. Therefore, the electrons on the right side of the first period (e.g., helium, neon) have higher ionization energies compared to the electrons on the left side (e.g., hydrogen, lithium).
What factors need to be considered when predicting the trend in ionisation energies across a period?
The charge on the nucleus.The distance of the electron from the nucleus.The number of electrons between the outer electrons and the nucleus.
What is the general trend in first ionization energy?
increases from left to right across a period.
The periodic trend for electronegativity is similar to what other trend?
The trend for first ionization energy
How do you calculate trend percentage?
trend percentage= (analysis period amount / base period amount) x 100
Out of carbon and fluorine and hydrogen and nitrogen and aluminum which element has the highest value for the first ionization energy?
Fluorine. Ionization energies are a periodic trend and they generally increase as you go up and to the right in the periodic table.See the chart in the Web Links to the left for a complete chart of the ionization energies of all the elements.
What is the group trend in the first ionization energies and why?
1. The ionization energy decrease down in the group.2. The cause is that the distance between the nucleus and the electron shell increase and the needed energy to extract an electron decrease.
What is is the trend across a period?
what is the reason for ionization energy across a period
What is trend in first ionization energies as one proceeds down the group 7A elements How this trends relates to the variation in atomic radii?
Ionization energies go down of course. This is because radii are becoming larger due to addition of electron levels. These farther from the nucleus electrons require less and less energy to liberate from the atom.
What is a trend seen on the period table?
"Electronegativity"
What other trend is similar to periodic trend for electronegativity?
The trend for first ionization energy
