Feedback

1

El titanio y el magnesio son metales ligeros

2

El aluminio es un metal ultraligero pero el titanio es tan sólo ligero, y por tanto no están en el mismo grupo.

3

Son metales pesados

4

No pertenecen al mismo grupo ya que el Zinc es pesado pero el Magnesio es ligero

5

Son metales pesados al igual que el plomo, el bronce y el cinc

6

El aluminio y el cobre son los más utilizados

7

El cobre es una Aleación de Cobre y Estaño y además un metal pesado

8

El Latón es una aleación de cobre y zinc y además un metal pesado

9

El plomo y además es muy tóxico cuando se inhalan sus humos

10

El Estaño es blando, brillante y no se oxida a temperatura ambiente

11

El cobre se oxida muy fácil pero tiene un monton de usos en nuestra vida diaria

12

El Zinc es gris azulado, brillante, no muy duro y débil a baja temperatura

13

El bronce es resitente a la corrosion y uno de los mas valiosos metales.

14

El latón es muy resistente a la corrosion y muy utilizado para la joyería

15

El Aluminio es el de menor densidad ya que es el más ligero

16

El Cobre no es una aleación

17

El cobre es el mejor conductor de la electricidad

18
