Moving down a group, the atomic radius increases because energy levels are being added with each period. So the outermost electrons are farther away from the positively charged nucleus, so the force of attraction between the nucleus and the outermost electrons is less. So it takes less energy to remove an electron.

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 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.
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
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 is the Trend in first ionization energy across a period?
As one proceeds down the group 7A elements, the first ionization energy decreases. this means that the outermost electron is more readily removed as we go down a group.
Which is more reactive sodium or barium?
sodium because it's the first group and first group are the most
