General Science GK — Frequently Asked Questions

Which chemical symbols are most often asked?+

Those that do not match the English name — gold (Au), silver (Ag), iron (Fe), sodium (Na), potassium (K) and lead (Pb) — because they derive from Latin.

Why is Vitamin D called the sunshine vitamin?+

Because the skin synthesises it when exposed to ultraviolet light from the sun, rather than relying solely on dietary intake.
