Respuesta:
a. Azufre
A = 32
Z = 16
p⁺ = 16 e⁻ = 16 n° = 16
Explicación:
Hallar cuántos protones, neutrones y electrones tiene.?
b. Hierro
A = 56
Z = 26
p⁺ = 26 e⁻ = 26 n° = 30
C. Potasio.
A = 39
Z = 19
p⁺ = 19 e⁻ = 19 n° = 20
d. lon oxigeno O-2
A = 16
Z = 8
p⁺ = 8 e⁻ = 10 n° = 8
e. lon aluminio Al+3
A = 27
Z = 13
p⁺ = 13 e⁻ = 10 n° = 14
