Why do element in the third period have lower ionization energies than elements in the second period?
Wiki User

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.

∙ 11y agoelectrons are closer to the nucleus, force between the nucleus and the electrons is greater, so it takes more energy to remove them.

∙ 12y agobecause the metallic elements tend to lose electrons instead the nonmetals elements tend to gain electrons.

∙ 14y agoBecause they have largest atomic size in their respective period so Ionization energy is lowest in the period.

Has largerst ionization energy in its period?
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.
What is the relationship between ionization energy and the alkali metals?
There is no relation ship. They have the lowest ionization energies.
Why do noble gases not have listed ionization energies?
The noble gases of each period have the highest ionization energies in their periods. Refer to the related link to see a graph showing the ionization energies of the elements across each period.
What element in period 3 has the highest second ionization energy?
Fluorine because it is the furthest right on the periodic table. Do no include noble gases in energies.
Ionization energies tend to do what from left to right across a period?
increase from left to right across a period.

What is the correlation of ionization energies to atomic radii for the elements?
In a group the ionization energy decrease when the atomic radius increase; in a period this relation is not generally valid.

There is no relation ship. They have the lowest ionization energies.

What element in period 3 has the highest second ionization energy?
Fluorine because it is the furthest right on the periodic table. Do no include noble gases in energies.
What exceptions are there in the increase of ionization energies across a period?
Boron and Oxygen Family
Ionization energies tend to do what from left to right across a period?
increase from left to right across a period.
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 type of elements tend to have low ionization energies?
The elements in the lower right part of the Periodic Table. Cs, Fr, Ra, Ba etc.
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.
To which third period element do these ionization values belong?
Al
Which element in the second period has the greatest ionization energy?
Neon
