Quiz: Masa nuclear y paresOnline version

Desafía tu conocimiento sobre masa, isótopos y pares.

by Hazell Matute
1

La abundancia relativa de isótopos se mide en unidades de masa atómica.

2

La abundancia natural relativa de isótopos de un elemento se da en porcentaje.

3

En la producción de pares, la energía mínima para crear un par electrón-positrón es 1.022 MeV.

4

En la aniquilación de pares, se emite un solo fotón de alta energía.

5

La energía mínima para crear un par electrón-positrón es 938 MeV.

6

La abundancia relativa de los isótopos de un elemento sirve para calcular la masa atómica promedio.

7

La masa nuclear es exactamente igual a la suma de masas de protones y neutrones.

8

La aniquilación de un electrón y un positrón produce típicamente dos fotones gamma de 511 keV en direcciones opuestas.

9

La masa nuclear es solo la parte central del atómo. No considera a los electrones

10

En algunos elementos solo existe un isótopo estable con 100% de abundancia.
