Answer:
90 neutrons
Explanation:
#neutrons = Atomic Mass - Atomic Number
= 170 - 80 = 90 neutrons
Explanation:
Rutherford → Nucleus
Rutherford in his model of an atom proposed that in an atom positive charge is concentrated in the center of an atom with he named nucleus and along with that also told that whole of an atom is also concentrated in the nucleus of an atom.
Bohr → Electron energy levels
Bohr in his structure of atom explained that electrons revolve around the nucleus in fixed orbit or shell or energy levels.These energy levels are stable and are stationary along with different energy value.
Schrodinger → Electron cloud and orbitals
Schrodinger proposed the mechanic model of atom in which he defined the location of electrons inside an atom by electron cloud in 3-d space.To define their location he introduced concept of quantum number.
Option C. Does not produce energy in the sun. Because energy in the sun is produced by fusion; this is the combination of two atoms, and that is the opposite to what the model shows.
