Nickel's protective oxide layer turns a reactive metal into a corrosion-resistant champion
12 days ago
0
What is the primary reason pure nickel resists corrosion despite being chemically reactive?
Nickel is completely inert and does not react with air at all.
It forms a passivation layer of nickel oxide that prevents further corrosion.
Nickel's golden tinge makes it naturally resistant to corrosion.

What role does the passivation layer of nickel oxide play in the chemical behavior of pure nickel?
It accelerates corrosion by reacting with oxygen to form rust.
It makes nickel completely inert and unreactive under all conditions.
It prevents further corrosion by protecting the metal surface from reacting with air.
