What elements have the highest and lowest ionization energy?
Helium has the highest first ionization energy and francium has the lowest first ionization energy.
What are the element within any giving periodic table would always have the lowest first ionization energy?
Francium in group 1 has the lowest first ionization energy.
What elements have the smallest value for first ionization energy?
Francium has the lowest 1st ionization energy. It badly wants to lose that electron. It is extremely energetically favorable. Basically the elements that are in group 1 and are in the lowest periods.
Based on the periodic table which element would be expected to have the lowest ionization energy?
Cesium (Cs)
Which elements on the periodic table have the lowest electronegativity?
Atoms to the left on the periodic table Atoms with a large atomic radius
What is the relationship between ionization energy and the alkali metals?
There is no relation ship. They have the lowest ionization energies.
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.
What elements have the highest and lowest ionization energy?
Helium has the highest first ionization energy and francium has the lowest first ionization energy.
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.

Francium in group 1 has the lowest first ionization energy.

Based on the periodic table which element would be expected to have the lowest ionization energy?

Which family of elements should have the lowest first ionization enegies?
the alkaline metals
What elements has the lowest first ionization energy Phosphorus scandium strontium or oxygen?
strontium
What elements has the lowest ionization energy element Rb Na C or F?
Rb
Elements with the highest ionization energy and thus the lowest reactivity are non-metals?
Noble gases
Where on the most reactive metals on the periodic table?
the bottom of the Periodic Table. why? a metal looses electrons and at the bottom of the periodic table is the lowest amount of ionization energy (the energy needed to remove electrons) with low ionization energy, not much energy is needed to remove those electrons making it faster and easier to do so.
