Note: There is no such clear division between metallic and non – metallic character. It is in a way that as we move across the periodic table, tendency to accept electrons increases which means non-metallic character increases.
Which of the following metallic element is the least reactive?
Platinum is the least reactive metal. It has remarkable resistance to corrosion, even at high temperatures, and is therefore considered a noble metal.
Which is the least non
The least non-metallic character will be in Iodine.
Which of the following non
Fluorine is the most reactive non-metal because it is the most electronegative of all of the non-metal elements of the periodic table. Due to its strong electro negativity & small size, Fluorine has a strong tendency to accept electrons from other atoms or ions. As a result it oxidises all other substances.
