Ok, to find the first ionization equation you have to start with the neutral calcium ion and then write the equation for the removal of one electron:

Ca(s) -----> Ca+(s) + e-

So the second ionization energy is just the removal of one more electron:

Ca+(s) ------> Ca2+(s) + e-

Good luck!

Aww, so, u been worrying about Oxygen ionization energy? worry no more because your answer is here finally!!

The first ionization energy of Oxygen is:

O(g) + e---------- O-(g) 1st EA=1314 KJ mol-1

second Ionization energy:

O-(g) + e- --------- O2-(g) 2nd EA=3388 KJ mol-1

please draw an arrow where u see (---------).

Hope this may help you!!

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 image can you draw to represent ionization energy?

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.

What is the energy needed to remove electrons from an atom called?

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


Does Ionization Energy Require an Equation?

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.


Why the second ionization energy of Ca is lower than the second ionization energy of k?

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

What do we mean by the first second third ionization energies for a particular atom?

First ionization energy is the energy required to remove the first outermost electron from an atom. The second ionization energy is the energy required to remove the next available electron, and is greater than the first IE. The third IE is that energy needed to remove the third electron, and is greater the the second IE.


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

Which has the larger sixth ionization energy Se or Br?

The first ionization energy is the energy that is required in order to remove the first electron from an atom in the GAS phase, the second ionization energy is the energy required to remove the second electron from an atom, etc. Ionization energy generally increases for every electron that is removed, and increases from left to right in the periodic table or if moving up the periods. In this case, from the periodic table (or according to Mastering Chemistry) Bromine (Br) has a larger sixth ionization energy than Selenium (Se).
