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.

la respuesta es si te gusta hacer lo que siempre haces cuando nunca ves a alguien en el espejo porque sabes que no siempre están ahí.

the answer is:  

line graphs show patterns in data with variables that change over time; whereas, circle graphs show data as parts out of a whole (such as out of 100%).
