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?
Who is more active Mg or Ca?
Ca is more active because it has an atom that is large. The larger the distance the smaller the force. If you want more information you should visit Which_is_more_reactive_Mg_or_Ca_Why
Does Mg have more metallic character than Ca?
Yes, Magnesium (Mg) has more metallic character than Calcium (Ca) because it has a smaller atomic radius and higher ionization energy, leading to stronger metallic bonding and more typical metallic properties like high electrical conductivity and ductility.
Ionization energy of Ca?
The ionization energy of calcium (Ca) is the energy required to remove one electron from a neutral atom of calcium in the gaseous state. The first ionization energy of calcium is approximately 590.6 kJ/mol, indicating the energy needed to remove the outermost electron. Additional ionization energies are required to remove subsequent electrons.
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)
Which element P or Ca has the highest first ionization energy?
The element P (Phosphorus) has a higher first ionization energy than Ca (Calcium). This is because Phosphorus has a smaller atomic size and higher effective nuclear charge compared to Calcium, making it harder to remove an electron from a Phosphorus atom than a Calcium atom.

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.
Using the periodic table choose the more reactive metal. Ca or Ra?
Radium (Ra) is more reactive than calcium (Ca). Both are alkali earth metals, but as you move down the group in the periodic table, reactivity increases due to the larger atomic size and the decrease in ionization energy. Therefore, radium, being lower in the group, is more reactive than calcium.
Why does magnesium have a higher third ionisation energy than aluminium?
Because aluminum has 3 electrons in its valence shell and when you get to the 3rd ionization energy it has an empty valence shell with a configuration as the noble gas Neon. Aluminum wants to stay at this state and will take a lot of energy to loose another electron from next energy level.
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.
