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 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.
Which of the group 3A elements has the largest ionization energy?
Beryllium is the group 3A element with the highest ionization energy.
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.
What is the trend ionization energy?
From left to right on the periodic table, ionization energy increases. From top to bottom in a column (group) the ionization energy decreases.
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 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.
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.
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
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?
the nobles gases are the greatest ionization group
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.
What is the trend ionization energy?
From left to right on the periodic table, ionization energy increases. From top to bottom in a column (group) the ionization energy decreases.
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.
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.
An atom has a first ionization energy of 496 kJmol and a second ionization energy of 4560 kJmol What group of the periodic table would the atom be in?
group 1
Why does the second ionization energy of Group 1 Elements greater than the first ionization energy of Group 1 Elements?
It takes more energy to knock off two electrons
