Because Be contains more protons and thus has greater nuclear positivity which exerts a stronger attraction for its electrons which requires more energy to remove one of the electrons leading to a higher ionization potential.

What is niobium's ionization energy?

Niobium element has more than one electron to be removed, it will have more than one ionization Energy (IE) 1st ionization energy: 652.1 kJ mol-1,2nd ionization energy: 1381.7 kJ mol-1,3rd ionization energy: 2416 kJ mol-1


Why 2nd ionization potential is greter than 1st ionisation potential of element?

In the first ionization an electron is removed from a neutral atom. In the second ionization an electron is removed from a positively charged ion. Since electrons carry a negative charge and opposite charges attract it is more difficult (i.e. takes more energy) to remove.


What has the greatest first ionization energy Li Be B or C?

It's carbon. The trend for 1st ionization energy is that it increases as you move left-to-right across a period. As you move in that direction across period 2, ionization energy increases, and since carbon is the most to the right, it has the highest 1st I.E.


What element has the highest ionization energy in group 4 of the periodic table?

Carbon has the highest ionization energy in Group 4 of the periodic table. This is because as you move across a period from left to right, the ionization energy generally increases due to increase in effective nuclear charge. Among the elements in Group 4 (carbon, silicon, germanium, tin, lead), carbon has the highest ionization energy.


How Which element require the greatest amount of energy to remove an electron?

Core electrons. Probably the 1s level would require the most ionization energy to pull these electrons.

Which element has a higher first ionization energy than chlorine Cl?

The element with a higher first ionization energy than chlorine Cl is fluorine F. Fluorine is located to the left of chlorine in the periodic table, which means it has a smaller atomic radius and stronger nuclear attraction, requiring more energy to remove an electron.


Which element's second ionization energy level is large compared to its first ionization energy?

Cl


Which elements on periodic table have the highest ionization energies?

The noble gases such as helium, neon, argon, and xenon typically have the highest ionization energies on the periodic table. This is because they have a full valence shell of electrons which makes it difficult to remove an electron.

What is the difference between 1st 2nd 3rd ionization energies?

The second ionization energy is always greater than the first because once you have pulled off the first electron, you are now trying to remove the second electron from a positively charge ion. Because of the electrostatic attraction between + and -, it is more difficult to pull an electron away from a positively charge ion than a neutral atom.


What is the 1st ionization energy for potassium?

The first ionization energy of potassium is about 419 kJ/mol. This is the energy required to remove one electron from a neutral potassium atom to form a potassium ion with a +1 charge.


What element has the highest ionization energy in group 4 of the periodic table?

Among the elements in Group 4 (carbon, silicon, germanium, tin, lead), carbon has the highest ionization energy.


What is the lowest first ionization energy?

The lowest first ionization energy is found in francium, the element with the highest atomic number. Francium has the lowest ionization energy because the outermost electron is held the weakest due to the large atomic size and shielding effects.

Core electrons. Probably the 1s level would require the most ionization energy to pull these electrons.
