Which sub-atomic particle is counted to learn the atomic number of that element?

1 answer:

6 0

Helium, with two protons, will have two electrons. In the chemical classroom, the proton count will always be equivalent to an atom's atomic number. This value will not change unless the nucleus decays or is bombarded (nuclear physics). Figure \(\PageIndex{1}\): The periodic table of the elements.

It is estimated that animal- or insect-pollinated plants produce 1000 pollen grains for each ovule; wind-pollinated plants produ

Ede4ka [16]

Explanation:

The plants which use animal or insects as pollination vector produce less pollen compared to the wind-pollinated plants.

This could be due to the reason that the chances of pollination by wind are less than the pollination by the animal or vectors.

The chances of pollination in animal pollination are high as the animals to feed on the useful product of plant will go to the other plants but in wind pollination, the chances are less as it depends on the speed and direction of the wind.

Thus, wind-pollinated plants produce high number of pollens.
