Why does an increase in atomic radius lead to a lower ionization energy?
An increase in atomic radius leads to a lower ionization energy because the outermost electrons are farther away from the nucleus, which weakens the attraction between the electrons and the nucleus. This makes it easier to remove an electron, resulting in a lower ionization energy.
What is the correlation of ionization energies to atomic radii for the elements?
There is an inverse relationship between ionization energy and atomic radius: as atomic radius increases, ionization energy decreases. This is because as the distance between the nucleus and valence electrons increases, the attraction between them weakens, making it easier to remove an electron.
Why is the first ionization energy of aluminium is less than the first ionisation energy of silicon?
Al has atomic number 13, and silicon has atomic number 14. The extra electron that silicon has is in a 3p orbital. In simple terms the extra charge on the silicon nucleus contracts the electron shell, this increases the energy to remove an electron and also decreases the atomic radius. Al, first ionization energy 577.5 kJ/mol, atomic radius 125pm Si, first ionization energy 786.3 kJ/mol, atomic radius 110pm
Which element has a smaller ionization energy Cs or Sr?
Cs has a smaller ionization energy than Sr. This is because Cs has a larger atomic radius and its valence electron is farther from the nucleus, making it easier to remove compared to Sr which has a smaller atomic radius and stronger nuclear attraction.
What periodic trends are inversely proportional to effective nuclear charge?
Atomic radius and ionization energy are inversely proportional to effective nuclear charge. As the effective nuclear charge increases, the attraction between the nucleus and the electrons increases, causing the atomic radius to decrease. In contrast, the ionization energy increases because it becomes harder to remove an electron from the atom due to the stronger attraction.

What can be perdicted about an element from its location in the periodic table?
Ionization energy, electronegativity, and atomic radius.

Which 3 atomic properties will you examine for periodic trends?
For periodic trends we will examine1- Electronic configuration 2- Ionization energy 3- Atomic radius
Which element has a smaller ionization energy Cs or Sr?
Cs has a smaller ionization energy than Sr. This is because Cs has a larger atomic radius and its valence electron is farther from the nucleus, making it easier to remove compared to Sr which has a smaller atomic radius and stronger nuclear attraction.
What periodic trends are inversely proportional to effective nuclear charge?
Atomic radius and ionization energy are inversely proportional to effective nuclear charge. As the effective nuclear charge increases, the attraction between the nucleus and the electrons increases, causing the atomic radius to decrease. In contrast, the ionization energy increases because it becomes harder to remove an electron from the atom due to the stronger attraction.
What trend it does the first ionization energy follow going across the periodic table?
The first ionization energy tends to increase across a period from left to right on the periodic table. This is due to the increasing nuclear charge and decreasing atomic radius, which leads to a stronger attraction between the electrons and the nucleus.
What is the relationship between elements and the periodic table and ionisation energy?
The relationship between atomic numbers and first ionization energies is that within the same period, as atomic number increases so does first ionization because as nuclear charge increases and atomic radius decreases, electrons become harder to remove. However, within the same group, the first ionization energy decreases as atomic number increases because of the added energy level, the electrons are farther from the nucleus and easier to remove.
What happens as we move down columns on the periodic table?
As you move down a column (group) in the periodic table, the electronegativity decreases, the ionization energy decreases, the electron affinity decreases, and the atomic radius increases.
What patterns do you notice as you move down the groups on the Periodic Table?
As you move down the groups on the Periodic Table, you generally observe an increase in the number of electron shells, leading to an increase in atomic size. Additionally, there is a trend of increasing reactivity in alkali metals and decreasing reactivity in noble gases as you move down a group. The ionization energy often decreases as you move down a group due to the increase in atomic size and shielding effect.
