Imagine that you helped to discover a new element; A=302;Z=119. How many protons, electrons, and neutrons are in each atom it this element?

Most smaller stars don't have a radiative zone.

The atomic nucleus made up from protons (yellow) and neutrons (blue) and held together by nuclear forces. nuclear forces (also known as nuclear interactions or strong forces) are the forces that act between two or more nucleons. they bind protons and neutrons (“nucleons”) into atomic
