Which of the following images most
accurately represents the structure of the atom?
An atom is the smallest unit of
ordinary matter. Atoms are made up of smaller pieces
of matter called subatomic particles. There are three types of subatomic
particles in the atom. The first type of subatomic
particle is the proton, which is positively charged. The second type of subatomic
particle is the electron, which is negatively charged. The third type of subatomic
particle is the neutron, which is neutrally charged.
The three types of subatomic
particles can be found in two main locations in the atom: in the nucleus in the
center of the atom or in energy levels outside of the nucleus. The nucleus is where protons and
neutrons are found. As protons are positively charged
and neutrons are neutrally charged, the nucleus has an overall positive charge. The energy levels outside of the
nucleus are where the negatively charged electrons are found.
From our discussion, we can see
that the image that most accurately represents the structure of the atom is the
image shown in answer choice (A).
