Question

CALCULEN EL NUMERO DE PROTONES ELECTONES Y NEUTRONES QUE CORRESPONDA A CADA ATOMO (SIMBOLO)A) Z=47 A=108 B)Z=82 A = 207

Answer 1

1)

Z = 47 Ag (plata)

protones = 47

electrones = 47

neutrones = A - Z = 108 - 47 = 61

2)

Z = 82 - Pb (plomo)

A = 207

protones = 82

electrones = 82

neutrones = A - Z = 207 - 82 = 125
