What is the charge on Ar ion?
Cl & K ions are isoelectronic with Ar.
How much iron does parsley have?
There is about 984 mcg of vitamin K per 1-cup serving.
Melting point of Argon?
The melting point of Argon is -189.3°C (83.8 K). At this temperature, solid Argon transitions to liquid form.
Does Argon have a bigger atomic radius then Neon?
I would say no. The potassium atom has 1 valence electron which is in the 4th valence shell. To form the potassium ion, it gives away this electron - thus becoming K+. Now, it has no electrons in the 4th valence shell - they are all in the 3rd valence shell. Argon also has all of its electrons in the 3rd valence shell. Also, K+ now has the same number of electrons as Argon. The reason why, at least I would say, argon has a larger radius than K+ is that even though they are in the same valence shell and have the same number of electrons, argon has one less proton than K+. This means that argon's nucleus does not pull in its electrons with quite as much force as K+. Therefore, the electrons (on average) are not as close to the nucleus as with K+. At least, this is how I would reason this out.
What ions has isoelectronic with argon?
Isodoetic ions with argon are K+, Cl-, Ca2+, and Sc3+, as they all have the same number of electrons as argon.
What temperature is argon liquid?
The melting point and boiling point of argon are 83.81 K and 87.302 K respectively. So argon is liquid in between these two temperatures.
What is the boiling and melting point for argon?
Argon (Ar) Melting points: 83.80 K, −189.35 °C, −308.83 °F Boiling points: 87.30 K, −185.85 °C, −302.53 °F
What does this statement indicate about argon?
Liquid argon exists only at temperatures lower than 151 K.
Can Ar-40 change back to K-40 talking about elements?
No, AR-40 cannot change back to K-40. Ar-40 is a stable isotope of Argon, while K-40 is a radioactive isotope of Potassium. Ar-40 is formed from the decay of K-40, but once it is formed, it will not transform back into K-40.
Which alkali metal is isoelectronic with argon?
Potassium (K) is isoelectronic with argon because they both have 18 electrons.
What degrees does argon become a gas at?
Argon is a gas above 87.30 K, −185.85 °C, −302.53 °F
What is the condensing temperature of argon?
The condensing temperature of argon is -185.86 degrees Celsius at atmospheric pressure.
