Which has highest ionisation enthalpy Cl or F?

Ionization energy increases with the increase in the atomic number when we move from left to right in a period and it decreases when we move down the group. There is more attractive force in fluorine hence the ionization potential of fluorine will be more than that of chlorine.

Which has a higher ionization energy Na or Cl?

The first ionization energy for sodium is one and one-half times larger than the electron affinity for chlorine. Thus, it takes more energy to remove an electron from a neutral sodium atom than is given off when the electron is picked up by a neutral chlorine atom.

Which has higher ionization enthalpy N or F?

Statement-1: Nitrogen atom has higher ionization energy than fluorine atom. Statement-2: Nitrogen atom has extra stable electronic configuration due to half filled p-subshell.

Which has lower ionization enthalpy Cl or F?

(i) Cl is below F in the group (or Cl is bigger than F), hence Cl has lower ionization energy than F. Thus, S should have lower ionization due to lower nuclear charge. (iii) K appears immediately after Ar in the periodic table. K belongs to group 1 of the periodic table; hence K should have lower ionization energy.

Which is bigger in size F or Cl?

The order in decreasing size would be Cl- > F- > Na+ > Li+. This can be explained by the following logic. Cl- would be the largest because it has the largest number of electrons, i.e. 18. So, the electron- electron repulsion would be maximum in the chloride ion.

Which of the following ionisation energy order is are correct a F Cl B F Cl C Cl F D Cl F?

F > Cl > Cl- > F.

Which element has the highest ionization enthalpy?

helium
Thus, helium has the largest first ionization energy, while francium has one of the lowest.

Why does N have higher ionization enthalpy than O?

Ionization energy can be thought of as the energy required to remove an electron from the valence shell of an atom. Nitrogen is known to have a half-filled p-orbital and is quite stable. Therefore, the ionization of nitrogen will be higher than that of oxygen.

Why ionization enthalpy of N is higher than O?

Because N has half filled orbitals, which is more stable than the orbitals of O so more energy is required to remove the electrons from N hence it has higher ionisation energy than O.

Which one has the bigger size Na or Cl Cl or F?

Because the effective nuclear charge rises from left to right in a period, Na has a larger size than Cl. The electronegativity of the nucleus increases as a result of this effective nuclear charge, as does the nucleus’s attraction to valence shell electrons.
