Question

for a neutral atom the atomic number tells you what? ¿qué te indica el número atómico en un átomo neutral? number of elements on the periodic table of elements number of protons number of chemical changes number of friends an element has number of neutrons number of electrons

Explanation:

The atomic number of a neutral atom is equal to the number of protons. In a neutral atom, the number of electrons is equal to the number of protons. The number of neutrons is not related to the atomic number. The number of elements on the periodic - table is not what the atomic number indicates. Chemical changes are not indicated by the atomic number. And "number of friends an element has" is not a relevant concept.

Answer:

Number of protons
