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 else can I help you with?
Are oxygen nitrogen an neon elements?
Yes, Oxygen (O), Nitrogen (N), and Neon (Ne) are all elements on the periodic table. Oxygen is the eighth element with atomic number 8, Nitrogen is the seventh element with atomic number 7, and Neon is the tenth element with atomic number 10.
What are the elements in the air?
The main elements in the air are nitrogen (about 78%), oxygen (about 21%), and traces of other gases like argon, carbon dioxide, and water vapor. These elements make up Earth's atmosphere and are essential for supporting life on our planet.
Does neon belong in the halogen family?
Neon is a member of the noble gas family. Neon is used to make neon signs and television tubes. Liquid neon is used as a cryogenic refrigerant.
What gases are not used during respiration?
Gases not used during respiration include nitrogen, neon, argon, and other noble gases, as they do not participate in the metabolic processes of extracting energy from nutrients. They are not involved in the exchange of gases within the respiratory system.
What is a neon cactus?
A neon cactus is an artificial cactus-shaped lamp that is typically made of neon lights. It is popular for home decor and can add a colorful and unique touch to any space. Neon cactus lamps come in various shapes and sizes to fit different preferences.
Which atom is larger neon or argon?
Argon is larger than neon because it has more electrons and a larger atomic radius.
Is neon bigger or smaller than argon?
Neon is smaller.
Are neon and argon atoms the same?
No. Neon atoms and Argon atoms have different atomic numbers. Which means they have different numbers of protons.
How do helium argon and neon differ?
Helium, argon, and neon are noble gases with different atomic numbers: helium (2), neon (10), and argon (18). They vary in terms of their densities, boiling points, and chemical reactivity. Neon has the lowest boiling point and argon has the highest atomic weight among the three.
What is the smallest atomic radius in period 5?
The smallest atomic radius in period 5 belongs to the element with the highest nuclear charge, which is iodine (I) from Group 17. This is because as you move across a period, the nuclear charge increases, leading to stronger attraction for the electrons and a smaller atomic radius.
What element is 4 times as heavy as neon atoms?
Argon is 4 times as heavy as neon atoms. Neon has an atomic number of 10 and an atomic mass of about 20.18 g/mol, while argon has an atomic number of 18 and an atomic mass of about 39.95 g/mol.
What is neon's atomic radius?
i dont know sorry
What is the element neon's atomic radius?
65 picometers.
What are the 3 lightest members of the noble gases?
Helium, neon, and argon are the three lightest members of the noble gases.
Is neon the smallest radius in period 2?
yes! It is because Neon has the largest atomic mass so the force of attraction between electrons and protons in the positively charged nucleus is the highest compared to all the other electrons in period 2.
Why is one mole of argon less than one mole of neon?
One mole of argon has a lower atomic mass compared to one mole of neon, as argon has a higher atomic number and thus heavier atoms. This means that there are more argon atoms in one mole compared to neon, but since each argon atom is heavier, the overall mass is less.
What is a mono atomic gases?
The noble gases, e.g. helium, argon, neon, etc. are monoatomic gases.
