In a group the ionization energy decrease when the atomic radius increase; in a period this relation is not generally valid.

What elements have the same ionization energy?
None of them do exactly. The elements' ionization energies definitely trend in a couple of ways though. The ionization energy variations tend to decrease as atomic number goes up and tend to increase as you remove more electrons from the atom.
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.
The atoms of the most active non-metals have?
large atomic radii and low ionization energies
Of the following elements which one would have the largest ionization energy Hydrogen (H atomic 1) Cesium (Cs atomic 55) Sodium (Na atomic 11) Potassium (K atomic 19)?
Hydrogen.
How does the ionization energy vary with atomic number within the group?
Ionization energy decreases with the rise of atomic number in a group of periodic table.

Why do group 1 elements have a low density?
The group one elements have the lowest ionization energies because of their large atomic size which makes the outermost electron only weekly held by the nucleus.
Are there any trends to the periodic table?
Atomic Radii,Ionic Radii, First Ionization Energy,Second and Higher Ionization Energies, Electron Affinity.

What is the relationship between elements and the periodic table and ionisation energy?
The relationship between atomic numbers and first ionization energies is that within the same period, as atomic number increases so does first ionization because as nuclear charge increases and atomic radius decreases, electrons become harder to remove. However, within the same group, the first ionization energy decreases as atomic number increases because of the added energy level, the electrons are farther from the nucleus and easier to remove.
Elements belong in upper ionization energy?
All of the elements on the top half of the periodic table belong in upperionizationenergy because the trend is top to bottom. Top being lowest and getting bigger as it goes down.------------------------------------------------------* In a group: the ionization energy decrease from the lighter elements to heavier elements.* In a period: the ionization energy increase from the left elements to the elements of the right.* When the atomic radius decrease the ionization energy increase.
The vertical columns on the periodic table are called?
The vertical columns on the periodic table are groups. Groups show patterns in ionization energies, electronegativity and atomic radius.

Hydrogen.
Why do element in the third period have lower ionization energies than elements in the second period?
With each additional period, there is an additional energy level, which means that the outermost electrons are farther away from the nucleus of the atom. This means that the attractive force of the positively charged nucleus is less, so it takes less energy to remove an electron from an atom in the third energy level than it does from an atom in the second energy level. Therefore, the elements in the third period have lower ionization energies than elements in the second period.
Why are the first ionization energies of some of the group 13 elements smaller than the first ionization energies of the nearby alkali earth metals in the same period?
I.E is the energy required to remove one electron from each atom to form gaseous charged cations.from group 2 to 12,atomic radius increases and hence there is less attraction from the protons in the atom.therefore,the energy required to remove an electron from the outermost shell will be less
How can you determine whether ionization energy is a periodic function of atomic number?
as atomic number increases, ionization energy also decreases
