(a) Isotopes of an element are chemically Similar.
(B) Noble gases show least reactivity.
(C) Ions are more stable than atoms.​

Answer 1

Hi mate

Here is your answer

(a) Isotopes of an element are chemically Similar.

Isotopes are elements with same atomic number and different atomic mass number. They have the same number of electrons and thus the same electronic configuration. ᴀs ᴛʜᴇ ᴄʜᴇᴍɪᴄᴀʟ ᴘʀᴏᴘᴇʀᴛɪᴇs ᴏғ ᴀɴ ᴇʟᴇᴍᴇɴᴛ ᴅᴇᴘᴇɴᴅ ᴏɴ ᴛʜᴇɪʀ ᴇʟᴇᴄᴛʀᴏɴɪᴄ ᴄᴏɴғɪɢᴜʀᴀᴛɪᴏɴ , ᴛʜᴇsᴇ ᴇʟᴇᴍᴇɴᴛs ᴀʀᴇ ᴄʜᴇᴍɪᴄᴀʟʟʏ sɪᴍɪʟᴀʀ.

(B) Noble gases show least reactivity.

Noble gases are the least reactive of all elements. ᴛʜᴀᴛ's ʙᴇᴄᴀᴜsᴇ ᴛʜᴇʏ ʜᴀᴠᴇ ᴇɪɢʜᴛ ᴠᴀʟᴇɴᴄᴇ ᴇʟᴇᴄᴛʀᴏɴs, ᴡʜɪᴄʜ ғɪʟʟ ᴛʜᴇɪʀ ᴏᴜᴛᴇʀ ᴇɴᴇʀɢʏ ʟᴇᴠᴇʟ. ᴛʜɪs ɪs ᴛʜᴇ ᴍᴏsᴛ sᴛᴀʙʟᴇ ᴀʀʀᴀɴɢᴇᴍᴇɴᴛ ᴏғ ᴇʟᴇᴄᴛʀᴏɴs, sᴏ ɴᴏʙʟᴇ ɢᴀsᴇs ʀᴀʀᴇʟʏ ʀᴇᴀᴄᴛ ᴡɪᴛʜ ᴏᴛʜᴇʀ ᴇʟᴇᴍᴇɴᴛs ᴀɴᴅ ғᴏʀᴍ ᴄᴏᴍᴘᴏᴜɴᴅs.

(C) Ions are more stable than atoms.

Ions are more stable than atoms. ᴛʜɪs ɪs ʙᴇᴄᴀᴜsᴇ ɪᴏɴs ʜᴀᴠᴇ ᴛʜᴇɪʀ ᴏᴄᴛᴇᴛ ʀᴜʟᴇ ᴍᴀɪɴᴛᴀɪɴᴇᴅ ᴛʜᴀᴛ ɪs ᴛʜᴇ ᴏᴜᴛᴇʀᴍᴏsᴛ sʜᴇʟʟ ᴏғ ᴛʜᴇ ɪᴏɴ ɪs ᴄᴏᴍᴘʟᴇᴛᴇʟʏ ғɪʟʟᴇᴅ ᴛʜᴜs ᴛʜᴇ ᴇʟᴇᴄᴛʀᴏɴɪᴄ ᴄᴏɴғɪɢᴜʀᴀᴛɪᴏɴ ᴏғ ɪᴏɴs ɪs ᴍᴏʀᴇ sᴛᴀʙʟᴇ ᴛʜᴀɴ ᴛʜᴀᴛ ᴏғ ᴀᴛᴏᴍ.
