An element has an atomic number of 76. What is the number of protons and electrons in a neutral atom of the element?

Answer 1

The number of (i) protons and (ii) electrons, are each #76#.

By definition, the atomic number, #Z#, is the number of protons, positively charged, massive, nuclear particles, contained in the nucleus. #Z# specifies the identity of the atom.

And if there are 76 positively charged particles, there must also be 76 negatively charged particles, 76 electrons, associated with the atom.
