, Pregunta 1 - SOLUCIÓN
Se pide calcular el número atómico de un elemento,
dados los datos para tres isótopos. Luego: A = p + n
Tenemos que: Remplazando en (1) te
La suma del número másico de tres isotopos es 153 p₁ + n₁ + p₂ + n₂ + p₃ +
(1) A₁ + A₂ + A₃ = 153 p₁ + p₂ + p₃ + 81 = 15
El promedio del número de sus neutrones es 27 3p = 153 - 81 = 72
(2) (n₁ + n₂ + n₃ ) / 3 = 27 P = 72/3 = 24
(n₁ + n₂ + n₃ ) = 27 x 3 = 81
Si son isótopos signific
tienen el mismo núme
(Z) pero diferente núm
(A), entonces el núme
Z = 24
