Write the appropriate symbol for each of the following isotopes: (a) Z = 19, A = 41 (b) Z = 46, A = 106 (c) Z = 52, A = 125 (d) Z = 38, A = 88

(a) ⁴¹₁₉K

(b) ¹⁰⁶₄₆Pd

(c) ¹²⁵₅₂Te

(d) ⁸⁸₃₈Sr

Explanation:

The identity of an element is its atomic number, by convention we write the atomic mass as superscript and the and the atomic number as subscript to the left of the element.

(a) Z = 19 A = 41 symbol: ⁴¹₁₉K

(b) Z = 46 A = 106 symbol: ¹⁰⁶₄₆Pd

(c) Z = 52 A = 125 symbol: ¹²⁵₅₂Te

(d) Z = 38 A = 88 symbol: ⁸⁸₃₈Sr
