Question

Which element has the symbol $Ti$ ?
A.Tin
B.Lead
C.Titanium
D.Thallium
E.Technetium

Answer 1

If you have knowledge about periodic table and the elements which are in periodic tables then only you can answer this question. It is a lustrous element having atomic number $22$ so if you can write the electronic configuration then after that you get the group number, period and block in which it is classified.

Complete step-by-step answer:
According to the modern periodic table that was designed by scientist Henry Mosely, he arranged the elements on the basis of atomic number and they all $118$ elements get successfully classified in $7$ periods and $18$ groups. Now when it comes to writing their name, it is much more difficult to write the full name of each element in the periodic table thus symbols are assigned to them.
Each element in the periodic table has different symbols if also their names start with the same letter. Like in the above example we have four elements whose name starts with (T) now to know how they differentiate. Let’s talk about Tin, having the chemical symbol $(Sn)$ and atomic number $50$ . We have seen this element as our household tin boxes for ingredients. Next we have lead, it is having the symbol $(Pb)$ and atomic number of $82$ , it is a heavy metal of silvery black color.
If we talk about Titanium, it is having the symbol $(Ti)$ and has atomic number $22$ , yes it is our answer to this question. Let’s see the other elements Thallium and Technetium both names start with letter T but their symbols are different. Thallium is having the symbol $(Tl)$ while for technetium it is having $(Tc)$ symbol.

Correct option is C.

Note: Periodic table is designed to assemble all $118$ elements according to the periodic trend like effective radii, electronegativity, ionization enthalpy etc. As we have so many elements which occur naturally there are different symbols for their representation. Many elements are there in periodic tables which occur as isotopes and isobars, but their symbol remains the same only difference is the atomic number and atomic mass.
