Na will have the highest [tex]IE_2[/tex] as its second electron will be in the highest energy level and more tightly bonded to the nucleus.
What is Nucleus?
- On the basis of the 1909 Geiger-Marsden gold foil experiment, Ernest Rutherford identified the atomic nucleus in 1911, which is the compact, dense region made up of protons and neutrons at the heart of an atom.
- Dmitri Ivanenko and Werner Heisenberg immediately created models for a nucleus made of protons and neutrons after the neutron was discovered in 1932.
- A positively charged nucleus and a cloud of negatively charged electrons that are held together by electrostatic force make up an atom.
- The electron cloud contributes very little to the atom's mass, which is almost entirely in the nucleus. The nuclear force brings protons and neutrons together to create a nucleus.
