Question

multiple choice question in the simple \bohr model\ of atoms shown here, the spheres that are identified by arrows represent which of the following? protons electrons daltons orbitals

Explanation:

In the Bohr atomic model, the central dense region is the nucleus, which contains protons (and neutrons). The small spheres orbiting the nucleus are electrons, while the arrows point to the nucleus's positively charged particles, which are protons. Daltons are a unit of mass, orbitals are part of quantum models (not Bohr's simple model), and electrons are the orbiting particles, not the ones in the nucleus marked by the arrows.

Answer:

A. Protons
