Which element has a lower first ionization energy than aluminum (Al)?
As an example potassium has a lower first ionization energy than aluminum (Al).
Which has lower ionization energy an atom with a small radius or an atom with a large radius?
Lower ionization energy would be associated with the larger atom, as the outer most electrons would be further from the nucleus, and not held as tightly.
Which of these elements has the highest first ionization energy Si or C?
The ionization energy is the energy needed to extract an electron from an atom; first ionization energy, second, third etc. can be measured. Reactive chemical elements have lower ionization energy.The first ionization energy for silicon is 786,5 kJ/mol.The first ionization energy for carbon is 1 086,5 kJ/mol.
Why is the first ionization energy of aluminum lower than the first ionization energy of gallium.if the increased proton no.is the case then why the i.enthalpy is increasing everywhere down the group?
It has something to do with the effective nuclear charge experienced by the valence electrons in Al and Ga. While aluminum's valence electrons are in the 3p shell, and there are 13 protons in the nucleus. Gallium's valence electrons are in the 4p shell, and there are 31 protons in the nucleus. Additionally, the atomic radius of gallium is not too much larger than that of aluminum. Thus, the electrons in gallium are pulled more strongly to the nucleus and they are more difficult to remove. A similar but lesser effect can also be seen in group IV/14, where Germanium has an almost identical first ionization energy to Silicon, and after the F shell is filled--thallium has a higher first ionization energy than Indium, and Lead has a higher first ionization energy than tin.
Does calcium have a lower first ionization energy level than sodium?
No. Calcium has TWO valence electrons, and Sodium has ONE. It is lot easier to take off one, than two you see. However, the second ionization energy of calcium IS however than the second ionization energy of Sodium. ;)

What element has a lower ionization energy than Na?
Potassium
Which element has a lower first ionization energy than element S?
Na, sodium
Between beryllium and barium which element will have the lower ionization energy?
Barium has more energy levels. So it has lesser ionization energy.
On the periodic table, the element in the lower left corner would have the lowestA. Atomic MassB.Atomic NumberC.Atomic RadiusD. Ionization energy?
A. Atomic Mass B. Atomic Number C. Atomic Radius D. Ionization energy
Which element has the lower ionization potential a.Mg b.Si?
mg
What is the ionizaton energy present example?
The energy required to remove electron from atom are called ionization energy. Larger atom or molecule have lower ionization energy and molecule have higher ionization energy.
Does K or Zn have lower ionization energy?
K
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.
Is it ionization energy is a periodic property?
Ionization energy generally increases across a period as a result of a higher nuclear charge, however there are some exceptions such as Boron which has a lower ionization energy than Beryllium (because it is in a P orbital), and Oxygen which has a lower ionization energy than nitrogen (Because ionization decreases the electron electron repulsion in its orbitals).
Which has lower ionization energy an atom with a small radius or an atom with a large radius?
Lower ionization energy would be associated with the larger atom, as the outer most electrons would be further from the nucleus, and not held as tightly.
