c) Write its electronic configuration.

d) Is ‘X’ a metal or a non-metal?

e) Write its name with symbol.​

Answer 1

Answer:

• Chlorine is having the atomic number 17.
• Chlorine is in group 17 of periodic table, also called the halogens, and is not found as the element in nature - only as a compound.
• Represented by the chemical symbol “Cl,” chlorine is number 17 on the Periodic Table of the Elements, indicating each atom of chlorine contains 17 protons and 17 electrons.
• Chlorine is the second halogen, being a nonmetal in group 17 of the periodic table. Its properties are thus similar to fluorine, bromine, and iodine, and are largely intermediate between those of the first two.
• Chlorine is a nonmetal because it does not have the characteristics of a metal. It cannot conduct electricity, it is not flexible, and it is not hard....
• It's electronic configuration is [Ne] 3s² 3p⁵
