Which element has 3 protons? Which element has 27 protons? What is the smallest part of the atom that has almost no weight? What element has the most stable isotopes? What element has 53 protons and 74 neutrons? What element has 4 protons 5 neutrons and 2 electrons?
Answer and Explanation: An atom that has more protons than electrons is called a cation. Ions are charged atoms or combinations of atoms. When an atom loses one or more... Learn more about this topic: Cation | Definition, Formation & Examples ...

Visible matter, also called baryonic matter, consists of baryons — an overarching name for subatomic particles such asprotons, neutrons and electrons. Scientists only speculate what dark matter is made of. It could be composed of baryons but it could also be non-baryonic, which means consisting...
In all atoms, the number of protons and the number of electrons is always the same. So nitrogen has 7 protons and 7 electrons, calcium has 20 protons and 20 electrons, and tin has 50 protons and 50 electrons. The number of neutrons is very roughly the same as the number of protons, ...
Protons are also heavy particles and they have a positive charge. Electrons are light particles and they are negatively charged. There are many important features that arise from considering the number of these particles in each atom. For example, the number of protons an atom has will determine...
The overall mass of an atom is determined by the mass of its protons, neutrons, and electrons. How does the mass ratio using H+ and H- differ from the atomic mass of hydrogen? The mass ratio using H+ and H- only takes into account the masses of these two particles, whereas the...
