Question

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

Answer 1

Concept Used:

The complete atomic symbol is written as:

^A_ZX

where,
A = mass number
Z = atomic number
X = symbol of the element

---

(i) Z = 17, A = 35

Atomic number 17 corresponds to Chlorine (Cl).

Complete symbol:

³⁵₁₇Cl

---

(ii) Z = 92, A = 233

Atomic number 92 corresponds to Uranium (U).

Complete symbol:

²³³₉₂U

---

(iii) Z = 4, A = 9

Atomic number 4 corresponds to Beryllium (Be).

Complete symbol:

⁹₄Be

---

Final Answer:

(i) ³⁵₁₇Cl
(ii) ²³³₉₂U
(iii) ⁹₄Be
