✔ 最佳答案
1 is false.
Neon is noble gas. It is very inert and there is no known reaction of neon.
Oxide ion can only exist in ionic compounds. There are a number of known reactions of oxide ion (e.g. oxidation to form oxygen gas, reaction with dilute acid, etc.)
Therefore, neon and oxide ion do not have similar chemical properties.
2 is true.
An atom and its ion have different chemical and physical properties.
For example, chlorine and chloride ion have different chemical properties (e.g. Chlorine is a strong oxidizing agent but chloride ion is not) and different physical properties (e.g Chlorine is yellowish green but chloride ion is colourless).
