Neon is smaller.
Argon has a higher boiling point than neon because argon atoms are larger and have stronger London dispersion forces, which require more energy to overcome and transition into the gas phase. Neon atoms are smaller and have weaker intermolecular forces, resulting in a lower boiling point.
Argon is larger than neon because it has more electrons and a larger atomic radius.
Among neon, argon, and helium, neon is the most reactive because it tends to form compounds with other elements under extreme conditions. Helium and argon are noble gases and are generally unreactive due to their stable electronic configurations.
Argon has a higher melting point than Neon. Neon melts at -248.6 degrees Celsius, whereas Argon melts at -189.4 degrees Celsius.
The rate of diffusion of a gas is inversely proportional to the square root of its molar mass. Since argon is heavier than neon (molar mass of 40 g/mol compared to 20 g/mol), argon will diffuse more slowly than neon.
Argon (Ar) has a smaller atomic mass than krypton (Kr). Krypton has an atomic mass of about 83.80 u, while argon has an atomic mass of approximately 39.95 u. Other elements with smaller atomic masses than krypton include neon (Ne) and helium (He).
Neon is better than argon and krypton for certain applications because it produces a bright, vivid light when electrified, making it ideal for neon signs and lighting. Neon is also more chemically inert than argon and krypton, which can make it more suitable for some specialized industrial processes.
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.
Argon, Ar. 0.93. Carbon dioxide, CO2. 0.033. Neon, Ne. 0.0018. Helium, He. 0.00052. Methane ... much higher than it is in air. ... Argon is the most abundant and most used of the noble gases.
Neon has a lower boiling point than krypton and argon because it is a smaller atom with weaker London dispersion forces between its atoms. Krypton and argon have more electrons and larger atomic sizes, leading to stronger intermolecular forces that require more energy to overcome, resulting in higher boiling points.
Sulphur.
because the size of helium is smaller than that of neon.
