How did bohr propose the particles within atom are arranged
a. protons and electrons form the nucleus with neutrons orbiting it
b. protons make up the atoms nucleus with electrons and neurons orbiting it
c. protons and neutrons from the nucleus of the atom with electrons orbiting it
d. neutrons make up the atoms nucleus with electrons and protons orbiting it

The correct answer is C. Protons and neutrons form the nucleus of the atom with electrons orbiting it

Explanation:

Bohr model was proposed by Niels Bohr in 1913 to explain the structure of atoms, in this Bohr stated electrons (particles negatively charge) orbit the nucleus that contains both neutrons (neutral particles) and protons (positively charged particles). Additionally, according to this model electrons were placed in different levels of energy and orbit the nucleus constantly, resembling planets in the Solar System, although the Bohr model was the first one that integrated principles related to energy levels and changes in energy in electrons. Thus, Bohr proposed "Protons and neutrons form the nucleus of the atom with electrons orbiting it".
