● Electrones: Corteza: - : Thomson (1932)
● Neutrones: Núcleo: 0 : Chadwick (1932)
_ Tabla periódica _
● (A) número másico: cantidad de protones y neutrones.
● (Z) número atómico: cuántos protones tiene el elemento,
normalmente el menor.
● La cantidad de electrones es la misma que la cantidad de protones
para mantenerse neutro.
● Casos donde no es neutro= - de electrones: CATIONES. + de
electrones: ANIONES.




● Si esta como
positivo hay más protones y si esta como negativo hay menos por lo
que para saber cuantos electrones hay se hace lo contrario.
_ Fórmula _
● n= A-Z


Reflexión

Hoy aprendí mucho más de las subpartículas que están en los átomos y
