The number of protons in an atom of krypton is 36.

<u>Explanation:</u>

The number written above the symbol of Kr in the periodic table represents the atomic number of the element . Then the number written in the below represents the mass number.

So the mass number of krypton is 84 and the atomic number of krypton is 36. As it is known that number of protons and electrons will be equal in a stable element. Thus, the krypton atom will be having 36 protons.

slamgirl [31]

Answer:

160.000 años corresponde a 16.000 décadas.

Explanation:

Para resolver correctamente el ejercicio debemos plantear la regla de tres simple de la siguiente manera:

1 década equivale a 10 años; A cuantas decadas equivalen 160.000 años?

1 década→10 años

          x    ←160.000 años

Debemos multiplicar 160.000 por 1 y luego dividir entre 10 ;

x=(\frac{160.000x1}{10})=16.000 décadas; en notación científica sería 16x10^3.

Respuesta: 160.000 años corresponde a 16.000 décadas.
