General Science question from Laboratory Attendant exam, 2026 by JKSSB

Which of the following statements is/are correct regarding metals? 

I.  Form basic oxides
II. Good reducing agents
III. High electronegativity
IV. High ionization energy

Choose the correct option: 

Last updated Jun 18, 2026
Correct Answer: Option A — Only I, II
Explanation:
I. Form basic oxides (Correct): Metals react with oxygen to form metal oxides, which are basic in nature because they react with water to form bases (such as sodium oxide reacting with water to form sodium hydroxide).

II. Good reducing agents (Correct): Metals have a strong tendency to lose electrons easily during chemical reactions. Because they donate electrons and reduce other substances, they act as excellent reducing agents.

III. High electronegativity (Incorrect): Metals have low electronegativity. They prefer to lose electrons rather than attract them. Non-metals are the ones with high electronegativity.

IV. High ionization energy (Incorrect): Metals have low ionization energy, meaning it requires relatively little energy to remove an electron from their outermost shell. This is why they easily form positive ions.
