How many protons are present in an atom which has an atomic number of 47?
Answer in units of protons.

Explanation:

The atomic number of an atom represents the number of protons in its nucleus. Therefore, 47 means that there are 47 protons in the atom's nucleus. In this case the atom is that of silver (Ag).

explanation:

earth's surface is mainly heated by the absorption of infrared radiation from the sun.

evaporation occurs because molecules in liquid water are warmed ( usually by the sun) and vibrate quicker, becoming less dense and rise.

condensation occurs because molecules in water vapor are cooled and therefore vibrate more slowly thus becoming more dense and eventually fall to earth.
