The only non - metal which forms positive ion is

Key Points

• Hydrogen is the only non-metal that can form a positive ion (H⁺).
• In its ionic form, hydrogen loses its single electron to become a proton (H⁺), which is a positively charged ion.
• Other non-metals typically gain electrons to form negative ions (anions).
• Hydrogen is unique due to its ability to exist as a cation (H⁺) in various chemical reactions, especially in acid-base chemistry.

Additional Information

• In the periodic table, hydrogen is placed in Group 1, but it is not an alkali metal.
• Hydrogen can also form negative ions (hydrides, H⁻) in certain conditions, showing its versatility in chemical bonding.
• Hydrogen is the most abundant element in the universe and plays a crucial role in many chemical processes, including the formation of water (H₂O).
• In its molecular form (H₂), hydrogen is a diatomic gas under standard conditions.
