The number of unpaired electrons in Cr (Z=24) is

Last Updated:

This SSC CGL Chemistry question asks: “The number of unpaired electrons in Cr (Z=24) is” The correct answer is 6. So 6 unpaired electrons. Redox questions should identify oxidation as electron loss or increase in oxidation number and reduction as electron gain or decrease in oxidation number. Acid basicity refers to the number of ionisable protons, not simply the number of hydrogen atoms written in a formula.

FAQ

SSC CGL Chemistry FAQs

Common questions and clear answers for this topic.

How many chemistry questions typically appear in the SSC CGL exam?

Chemistry usually contributes a handful of questions within the General Awareness section, generally covering basic concepts rather than calculation-heavy problems.

Which chemistry topics are most important for SSC CGL preparation?

Atomic structure, periodic table trends, acids-bases-salts, metals and non-metals, and carbon compounds are the areas that appear most consistently across past papers.

Is NCERT chemistry enough to prepare for SSC CGL?

NCERT textbooks from classes 9 and 10 cover most of the conceptual base needed, though supplementing with general knowledge about everyday chemical compounds helps too.

What is the best way to remember chemical reactions and formulas for SSC CGL?

Linking reactions to real-world examples, like rusting or antacids, makes them easier to recall than memorizing formulas in isolation.

Does the SSC CGL chemistry syllabus overlap with the school board syllabus?

Yes, a large part of the syllabus mirrors class 9 and 10 science, making school-level revision a practical starting point.
