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

What ionization energy and which elements has the highest and lowest ionization energy?
Ionization energy is the energy required to remove an electron from a gaseous atom or ion. The element with the highest ionization energy is helium (He), due to its small atomic size and strong nuclear charge. In contrast, cesium (Cs) has one of the lowest ionization energies, as its larger atomic radius and increased electron shielding make it easier to remove an outer electron.
Which 3 atomic properties will you examine for periodic trends?
For periodic trends we will examine1- Electronic configuration 2- Ionization energy 3- Atomic radius
How does calcium first ionization energy compare to the first ionization energy of magnesium and potassium?
Calcium's first ionization energy is lower than that of magnesium but higher than that of potassium. This is due to the increasing atomic size down the group, which decreases the effective nuclear charge felt by the outermost electron. Magnesium, being higher in the group, has a smaller atomic radius and a stronger attraction between the nucleus and its valence electron, resulting in a higher ionization energy. Conversely, potassium, being further down the group, has an even larger atomic radius, leading to a lower ionization energy than calcium.
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.
