Group 1 because across group 1 to 8 nuclear force of attraction increases to a significant extent and as a result greater amount of energy is needed to remove an electron. More specifically Fr has the lowest IE and He has the highest

What elements has the lowest ionization energy element Rb Na C or F?

Element Rb (Rubidium) has the lowest ionization energy among Rb, Na, C, and F. This is because as you move down a group on the periodic table, the ionization energy typically decreases due to the increase in atomic size. Rubidium is located below sodium (Na) in the same group, so it has a lower ionization energy.


What are the element within any giving periodic table would always have the lowest first ionization energy?

Elements in the alkali metal group (Group 1) have the lowest first ionization energy within any periodic table. This is because they have a single electron in their outermost shell, which is easier to remove compared to other elements. Sodium and potassium are examples of alkali metals.


What element has the lowest ionization energy out of Lithium Boron Oxygen Fluorine Neon?

Among the given elements, neon has the lowest ionization energy. It is in Group 18 (Noble Gases) of the periodic table, and noble gases have the highest ionization energies due to their stable electron configurations.


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

Francium would be expected to have the lowest ionization energy, as it is located in the alkali metal group at the bottom left of the periodic table. Alkali metals typically have the lowest ionization energies due to their large atomic size and low effective nuclear charge.


In ionization energy how does the property varies within a group?

The ionization energy decrease moving down in a group.


Which of the group 3A elements has the largest ionization energy?

Beryllium is the group 3A element with the highest ionization energy.


Which of the group IIIA (13) elements has the largest ionization energy?

The element with the highest first ionization energy in group 14 is carbon.


What is the second ionization of energy and how does it work?

Imagine that one electron has already been removed from an atom, the energy used to accomplish this is the 1st ionization energy. Now more energy is needed to remove a 2nd electron. That is the 2nd ionization energy.


What element has the highest ionization energy in group 4 of the periodic table?

Carbon has the highest ionization energy in Group 4 of the periodic table. This is because as you move across a period from left to right, the ionization energy generally increases due to increase in effective nuclear charge. Among the elements in Group 4 (carbon, silicon, germanium, tin, lead), carbon has the highest ionization energy.


Out of sodium potassium rubidium and cesium Which element has the greatest ionization energy?

Sodium has the greatest ionization energy of the four elements listed from column 1 of a wide form periodic table. Among this group of metals that readily form cations, the largest always has the lowest ionization energy and the smallest has the most. This is generally ascribed to the fact that the valence shell electron is further from the nucleus in the largest element and nearest in the smallest element.


What is the group trend for the ionization energy for the alkali metals?

As you go down the group (any group), ionization energy decreases. So in terms of ionization energy, for the alkali metals, Lithium > Sodium > Potassium > Rubidium > Caesium > Francium
