Question

The symbol of tin is
A. Sn
B. Pb
C. An
D. Br

Answer 1

Hint: Tin lies in group 14 and has atomic number 50. Stannum is the word used for tin in naming its compounds.

Complete step-by-step answer:
The correct answer is A.
The symbol of tin is Sn. It lies in post transitional in group 14. Tin got its atomic name from Latin and the Latin word for tin is stannum that’s why its symbol is Sn. Atomic weight of tin is 118.7 whereas its atomic number is 50. The physical state of tin is solid. Electronic configuration of tin is represented as $[Kr]4d^{10}5s^25p^2$.
Tin is an inorganic compound which if by any chance enters your body will leave. It does not harm you. Tin has very low temperature. It is a non-toxic metal which melts around 500 degree Celsius. This metal is very casteable that it can be molded and it has a very brilliant look. But this metal is very expensive, that is the only reason it is not used much. The compounds of tin are named by stannous like stannous chloride.

Note: Elements of group 14 constitute 5 elements:
Carbon(C), silicon (Si), germanium (Ge), tin (Sn), lead (Pb).
Group 14 is a post transitional series. The elements of this group have 4 electrons in their valence shell. Group 14 prefers to make covalent bonds as 4 electrons are difficult to give similarly 4 electrons are difficult to take for any element. The symbol of tin is Sn which is because its atomic name is derived from Latin which is sternum.
