Neon is an element because it is a pure atom
It could pass by a large enough object that has enough gravity to pull the object into its orbit and the object would stay in orbit because it has centripetal force.
A. Oxygen. Oxygen has an atomic mass of 16. The atomic mass of an atom is the combined weight o the protons and neutrons. Since Oxygen's atomic mass is 16, it has 8 protons and 8 neutrons.
In his proposed model of the atom, J.J. Thomson imagined the atom contained<u><em> electrons and space filled with wispy positive charge </em></u> .
I hope this helps you and have a great day!! :)
<span>1.Schrodinger's equation deals with the modern atomic theory.
2. They are tested by many scientists.
3. I am not sure on this one.
4. It depends on the atomic weight of the boron. There are 5 protons for sure, but the number of neutrons depends on the isotope.</span><span>
