I don’t know much about this but I do know that you can figure out which molecule that is by counting the amount of positive charged particles by the neutral or negative charred particles. Then using a periodic table. Hope this helps enough

Answer:

That element is Helium.

Explanation:

We can see in the image above that the element has two negative particles (which are the electrons), two positive particles (which are the protons) and two neutral particles, without electrical charge (which are the neutrons).

If we look for a periotic table and observe the electron numbers of the elements and the atomic number (number of protons), we realize that the only elementp that has two protons and two electrons is Helium.

Getting the necessary food nutrients on the other hand will boost one's immunity and enable one to develop resistance to diseases. Restricting one's food to a limited type of food is very bad and can have fatal consequences.
