Argon. As you go across (left to right) on the Periodic Table the energy of an atom increases. Argon is farthest left of chlorine therefore making Argon have a higher ionization energy level.

Why is chlorine more reactive than argon?
Chlorine is very reactive because it is a halogen (Group VII of the Periodic Table) and it does not have a filled outermost energy level. Argon is unreactive because it is a noble gas (Group VIII of the Periodic Table). Its outermost energy level is full.
Is the electron arrangement in an ion of chlorine similar to neon or argon?
Argon
What is he element is found in the same period as sulfur and argon and that is more reactive than sulfur and argon?
Chlorine
Why is the ionization energy for Neon greater than Fluorine?
Neon had a higher proton charge than Fluorine (first I.E increase) Neon the same radius, due to the same amount of shells, but it is slightly smaller than fluorine due to a higher number of protons in the nucleus attracting the electrons in the outer shells close (Doesn't really affect first I.E.) Neon also has the same amount of shielding electrons, due to having the same number of sub-shells, therefore this doesn't really affect I.E. either However the largest factor is that the 2p sub shell in neon is full, whereas in fluorine it is not, a full sub shell means that the atom is more stable therefore ionization energy significantly rises. Therefore Neon, overall has a larger first ionization energy. Neon- First I.E.=2080.7 Fluorine-First I.E. =1681.0
How many electrons does chlorine need to have a full outer shell?
1 additional electron will give chlorine 8 in the valence. You can see in the Periodic table, that Chlorine is next to Argon ( 1 to the left of it) so it needs 1 more electron to have the same configuration as Argon.
What is the ionization energy for Ar?
Argon's ionization energy is 39.948
What is Argon Ionization Energy?
15.759
What is lowest second ionization energy on argon calcium or potassium?
calcium
Why does helium has a higher first ionization energy than argon?
The ionisation energy depends on the orbital from which the electron is removed and also the distance of the orbital from the nucleus. In the case of Helium, the electron is removed from 1s orbital whereas in the case of argon it is from 3p orbital. As 1s is closer to the nucleus, the force of attraction experience by these electrons is higher and hence helium will have higher 1st ionisation energy.
Is oxygen chlorine silicon or argon?
argon
Is chlorine isoelectronic with argon?
No. Chlorine has 17 electrons whereas argon has 18 electrons. But chloride ion has 18 electrons and is isoelectronic with argon.
Why is chlorine more reactive than argon?
Chlorine is very reactive because it is a halogen (Group VII of the Periodic Table) and it does not have a filled outermost energy level. Argon is unreactive because it is a noble gas (Group VIII of the Periodic Table). Its outermost energy level is full.
What happens if you mix chlorine argon and sodium together?
Just by mixing there will be no reaction between any of these. However if suitable energy is supplied then sodium may combine with chlorine to form sodium chloride. Argon is chemically inert and does not react.
What is the ionization point of argon?
The first is 1521 kJ/mol.
Argon is a stable gas with a very high ionization energy Which statement explains why?
It has a full outer shell of electrons
Is argon chlorine?
No. Argon and chlorine are two different elements. Both belong to period 3. But chlorine is a group 17 element (with 17 protons) whereas argon belong to group 18 and has 18 protons.
What element is a noble gas with 22 neutrons?
The element is argon and the isotope is 18Ar40
