An element has an atomic mass number of 16 and an atomic number of 7. The element has _ protons and _ neutrons

7 protons and 9 neautrons

Explanation:

neautrons = atomic mass - atomic number

16-7= 9

protons= number of electrons= number of protons (this can be seen in the atomic number)

the answer will be a) proteins i believe

answer: ice crystals in air

the water from the water body or another source of water gets evaporated as water vapor as an effect of heat on water. these water vapor rises in the upper layers of the earth atmosphere under high atmospheric pressure. the atmospheric pressure of these water molecules starts to decrease due to the effect of cold air. the invisible water vapor condenses into visible water droplets and ice crystals.these ice crystals and water droplets being less denser than the surrounding air floats on air as clouds.
