Question

n atom of an element is shown by the model. mc016-1.jpg How is this model useful? It shows how electrons are distributed in the shells of an iron atom. It shows how electrons are distributed in the shells of a cobalt atom. It shows how orbitals are distributed in the shells of an iron atom. It shows how orbitals are distributed in the shells of a cobalt atom.

Answer 1

Atom is the smallest unit of any element which can participate in a chemical reaction. Each atom of any element contains a central nucleus and outer shells

the central nucleus contains positive protons and neutral neturons

The outer part of nucleus has shells. These shells are occupied by electrons.

so the model must be a representation of how electrons are distributed in the shells of an iron atom

Answer 2

I believe it is useful as it shows how electrons are distributed in the shells (energy levels) of an iron atom. An atom is the smallest particle of an element that can take part in a chemical reaction. It contains the nucleus and the shells (energy levels). the nucleus contains protons and neutrons while the shells contain electrons.
