How can you determine the number of electrons surrounding the nucleus of an atom of any of the elements listed in the table?

Answer 1

Any element's atomic number generally corresponds to the quantity of protons in its nucleus.

Furthermore, in neutral atoms—that is, atoms that are not ions—the number of protons is equal to the number of electrons.

As a result, the number of electrons encircling an atom's nucleus is its atomic number.

Any element listed in the periodic table can have its atomic number used to calculate the number of electrons surrounding its nucleus. The atomic number of an element is the number of protons in its nucleus, which is also equal to the number of electrons in a neutral atom. Using the atomic number of an element, you can calculate the number of electrons surrounding its nucleus.
