How does calcium's first ionization energy compare to the first ionization energy of magnesium and potassium?
First ionization energy of magnesium = 870/ kj/mol First ionization energy of phosphorous = 589 kj/mol So, magnesium has the larger ionization energy required to pull the first valance electron. Do you know why?
Rank the following elements in order of increasing first ionization energy C Ne Sr Mg Be?
Ne (Highest First Ionization Energy) C Be Mg Sr (Lowest First Ionization Energy)
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 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.
Ionization energy of Ca?
No it has high ionization potential compared to Na, K. This is because it has a very small atomic radius so there is more attraction of the nucleus to the electrons. So it is not easy to remove electrons from it when compared to Na and K.
Which element P or Ca has the highest first ionization energy?
In general, ionization INCREASES as you move to the right and up in the periodic table, making P (Phosphorus) higher than Ca (Calcium).

What is an equation for the second ionization energy of calcium?
The Chemical equation of calcium hydroxide is Ca(OH)2

What has a larger atomic radius Cl ion or Ca ion?
Calcium has the larger atomic radius than chlorine. Calcium has four energy levels, whereas chlorine has three energy levels. The higher the energy level, the farther it is from the atomic nucleus.
How can atoms with fewer than 8 valence electrons fill their outmost energy level?
They ca fill their outmost energy level by gaining or losing electrons.
Is MBA better than CA?
Both the degrees have there own important. CA is 50 times more tough than MBA. CA qualified individual earn a lot when compare to the MBA student. But again it depends on geographical location. If the demand of MBA is high we will get a higher pay check.
Why is ca home owners insurance so much higher than Oregon?
Coastal areas tend to get more storm damage than inland areas.
Is lithium behaves different from the other alkali metals true or false?
True. Although lithium is an alkali metal it is quite different from the other alkali metals. In fact it can generally behave more like an alkaline earth metal, such as Magnesium (Mg), Calcium (Ca) Strontium (Sr) and Barium (Ba). One of the major characteristics of the alkali metals is their low ionization energy, which is why lithium can easily be present in its ionic form of Li+. However, lithium posses the highest ionization energy of the alkali metals
