Write the complete symbol for the atom with the given atomic number (Z) and atomic mass (A) (i) Z = 17, A = 35. (ii) Z = 92, A = 233. (iii) Z = 4, A = 9.

(i)
Answer

1735Cl^{35}_{17}\text{Cl}

(ii)
Answer

92233U^{233}_{92}\text{U}

(iii)
Answer

49Be^{9}_{4}\text{Be}

Explanation

The composition of any atom can be represented by using the normal element symbol (X) with the atomic mass number (A) as the super-script on the left hand side and the atomic number (Z) as the subscript on the left hand side, i.e., ZAX^{A}_{Z}\text{X}. Using this notation, we place the given mass number (A) at the top left and the atomic number (Z) at the bottom left of the respective element symbols.
