Could a nucleus that has more than one proton but no neutrons exist? explain.

No, it does not exist.

Explanation:

Hello,

Taking a look into the atom, one must remember that the number of neutrons is computed via:

In such a way, if a nucleus has no neutrons and more than 1 protons (equal to the atomic number) the only possibility is that its atomic mass equals the atomic number (it is just the case of hydrogen) nonetheless, without any neutrons, the protons will repel each other since the nucleus would have multiple positive charges, thus, it does not exist.

Best regards.

a rain shadow is a dry region of land on the side that is protected against the prevailing winds of a mountain range. the prevailing winds are the winds that occur most of the time in a particular place of the earth

prevailing winds carry air toward the mountain range. as the air rises up over a mountain range, the air cools, water vapor condenses, and clouds form. on this side of the mountains, called the windward side, precipitation falls in the form of  rain  or snow. this dry air produces a  rain shadow.
