Question

A student drew a diagram of the quantum model of an atom, as shown. A small circle is shown. Six light gray spheres and six dark gray spheres are shown inside the circle. On the outer side of the circle is a diffused shaded circular region. This diffused shaded circular region has two distinct bands of dark gray shading in it. Which of the following explains if the student's diagram is correct or incorrect? The diagram is incorrect because electrons follow orbital rings around the nucleus. The diagram is incorrect because there is only a single type of particle at the center of the atom. The diagram is correct because electrons are present in a negatively charged cloud outside the nucleus. The diagram is correct because all electrons can be accommodated in two electron clouds around the nucleus.

Answer 1

Answer:

The diagram is incorrect because there is only a single type of particle at the center of the atom.

Explanation:

The small circle at the centre of the sphere which contains six light gray spheres and six dark gray spheres represents the nucleus of the atom which is found at the centre of the atom.

The nucleus contains only one type of particle which is the proton. Hence the representation of two particles at the centre of the circle makes the model incorrect.
