The Chemical equation of calcium hydroxide is Ca(OH)2
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. ;)
Lithium ====> Li , Electronic configuration { 1S2 2S1 } So we have only first ionization An the second will be from Complete stable energy level that need great amount of energy to remove it And that is impossible
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.
Neon
By all means. If an atom is neutral, then it has no need to attract or repel other atoms. But if it becomes positively or negatively charged (by taking away or adding one electron (btw: negative ionization is healthy)) then it will naturally attract it's opposite and attach to closest possible match.
calcium
The second ionization energy of calcium is greater than that of potassium. This is because calcium, with its higher nuclear charge and smaller atomic size compared to potassium, holds onto its electrons more tightly.

You could draw it using Lewis structures, where valence electrons are represented by dots. You can also express it in equation form. The first ionization of calcium, for instance, could be expressed as: Ca --> Ca+ + e- As you can see, neutral calcium loses an electron to form the calcium +1 cation. Of course, we know that calcium will lose another electron as well, which can be expressed in the equation for the second ionization of calcium: Ca+ --> Ca++ + e- Normally, calcium will not experience a third ionization, because with two valence electrons, it has now achieved a full octet and is isoelectronic with argon.

ionization potential energy. but remember the atom must be neutral .

hydrogen has only one electron so after you remove that electron you do not have any electrons left to remove so hydrogen doesn't have a 2nd ionization energy. hydrogen has 1 proton and 1 electron.
Because with the 2nd ionisation of K, you are trying to take an electron from a fully filled orbital (octet rule) whereas with calcium it is getting down to a fully filled orbital
