The first ionization energy of mercury is 10.44 eV, while the second ionization energy is 18.76 eV. These values represent the energy required to remove one or two electrons, respectively, from a gaseous mercury atom to form a positively charged ion.
Nickel has two unpaired electrons.
The difference in mass between the two nickels is 0.168 grams. The first nickel weighs 4.7 grams and the second nickel weighs 4.868 grams.
Second ionization energy of fluorine is the amount of energy needed to remove an electron from a unipositive fluorine atom (F+)to form F2+,in all the gaseous state
An ionized helium nucleus, i.e a helium atom that has had been stripped of it's three electrons, to create a particle with a charge of +3. Such a particle is unlikely to occur in nature, because of the extremely high first and progressive ionization energies of helium arising from it's complete outer electron shell.
Both Group IA and IIA elements have low ionization energies because they have one or two valence electrons that are easily removed. Group IA elements have a lower ionization energy compared to Group IIA elements due to the increased distance from the nucleus and increased shielding effect in Group IA.
The first ionization of tin is given as , Sn becomes Sn+1 and 1 e- . The amount of energy released is 708.6 kJ/mol . The second ionization reaction is Sn+1 becomes Sn+2 and 1 e- with 1411.8 kJ/mol energy released.
Alkali gases only have 1 electron needing to be removed to reach a stable noble gas configuration. Alkaline earths have two electrons. Alkali metals thus have the lower ionization energy of the two groups.

This is my QustionListed below are ionization energies for removing successive electrons from various atoms of the third period. Which of the following lists corresponds to the ionization energies for phosphorus?a. 496 kJ, 4,560 kJ (I.E. for the first two electrons)b. 738 kJ, 1,450 kJ, 7,730 kJ (I.E. for the first three electrons)c. 578 kJ, 1,820 kJ, 2,750 kJ, 11,600 kJ (I.E. for the first four electrons)d. 786 kJ, 1,580 kJ, 3,230 kJ, 4,360 kJ, 16,100 kJ (I.E. for the first five electrons)e. 1,012 kJ, 1,900 kJ, 2,910 kJ, 4,960 kJ, 6,270 kJ (I.E. for the first five electrons)
First an explanation in terms of ionization energy and electron affinity: Metals have low ionization energies and readily form ions. Non-metals have high electron affinities- so put them together and electron transfer is favourable. Two bonded non metals are generally covalent- their ionization energies are high. Now an explanation in terms of electronegativity (electronegativity is related to ionization energy and elctron affinity) metals have low electronegativity- non metals are comparativelly high. So electron transfer is likely. Just a cautionary word about compounds of non metals never being ionic-- what about PBr5- a binary compound of two non metals- in the solid state this has the structure PBr4+ Br-...bit of a cheat really as there is a polyatomic ion in there but it is ionic!
There are no known "infinite energies" in our real Universe.
Alkali metals (group 1 elements) have one valence electron. Hence have one ionization energy Alkaline earth metals (group 2 elements) have two valence electron. Hence have two ionization energy
Ionization enthalpy of isotopes should be theoretically the same.But the recorded values aren't equal..nobody knows why..

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. ;)
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.
