Answer:

Co-59 and Co-60 differ in the number of neutrons.

Explanation:

Co-59 and Co-60 are isotopes of one another. Isotopes differ from one another as they have different mass number but same atomic number. Mass number is the sum of the number of protons and neutrons. As they have the same atomic number they have same number of protons. They have different number of neutrons.  

Co has atomic number 27. So Co-59 and Co-60 have (59-27) or 32 and (60-27) or 33 number of neutrons respectively.

balu736 [363]

Answer:

Beginning from the innermost layer and moving towards the outermost of the sun that has six layers.

1. Innermost layer is the core: All the energy of the sun comes from core. Here hydrogen and helium are components that are present.

2. Radiative zone: The high-energy photons are move from the innermost core to the second innermost radiative zone.

3. Convective zone: It is a comparatively cooler layer to the core and radiative zone.

4. Photosphere: It is the 4th innermost region with sunspots and called the magnetic field of the sun.

5. Chromosphere: This red color layer with filaments of gas is cooler than the photosphere.

6. Corona: It is the outermost layer of the sun and the temperature is much higher here.
