Question

9 what does the atomic number in the periodic table represents? a atomic weight b number of neutrons c number of electrons d number of protons

Explanation:

The atomic number of an element in the periodic table is defined as the number of protons in the nucleus of an atom of that element. In a neutral atom, the number of electrons is equal to the number of protons, but the atomic number specifically refers to the proton - count. Atomic weight is related to the sum of protons and neutrons, and the number of neutrons is not what the atomic number represents.

Answer:

D. Number of protons
