No. Other than both being gasses at room temperature they are quite different.
The element is argon and the isotope is 18Ar40
chlorine size is smaller
Sodium chloride is it an entirely different substance with its own unique properties.
No noble gas is isoelectronic with the element chlorine. But argon is isoelectronic with the chloride ion.
All have the outermost shell of electrons completely filled.
Argon
Fluorine or Bromine have similar properties to chlorine because both are halogens.
Argon is a nobel gas. Nobel gases are located in Group 18. Elements have similar properties within the same group. Argon has similar properties to Helium, Neon, Krypton, Xenon, and Radon.
Fluorine, Bromine, and Iodine have similar properties to chlorine
Gggg
They have a different number of valence electrons.
YES, very similar properties. Both Fluorine and Chlorine are in Group (or Family) 17. Fluorine is in Period 2 and Chlorine is Period 3
All of the noble gases have similar chemical properties; helium, neon, argon, krypton, xenon, and radon.
pupu
Elements similar to chlorine will be located in the same group(17).
argon
No. No two elements have the same chemical properties. However, the chemical properties of fluorine and chlorine are similar. Since they are similar, they are placed in the same group, group 17, on the periodic table.
