Nitrógeno Z=7; A=15 p + = _________ e - = _________ n o = __________  Magnesio Z=12; A=24 p + = _________ e - = _________ n o = __________  Hierro Z=26; A=56 p + = _________ e - = _________ n o = __________  Paladio Z=46, A=106 p + = _________ e - = _________ n o = __________  Cerio Z=58; A=140 p + = _________ e - = _________ n o = __________  Oro Z=79; A=197 p + = _________ e - = _________ n o = __________

Answer 1

Respuesta:

Nitrógeno Z=7; A=15 --------> p + = 7 e - = 7 n o = 6

Magnesio Z=12; A=24 -------> p + = 12 e - = 12 n o = 12

Hierro Z=26; A=56 -----------> p + = 26 e - = 26 n o = 30

Paladio Z=46, A=106 --------> p + = 46 e - = 46 n o = 60

Cerio Z=58; A=140 -----------> p + = 58 e - = 58 n o = 82

Oro Z=79; A=197 --------------> p + = 79 e - = 79 n o = 118

Explicación:

A = Z + n

p+ = e- = Z
