Taking into account the constitution of an atom and the definition of a neutral atom, aluminum has 13 electrons.
What is the constitution of an atom
An atom is the smallest constituent unit of ordinary matter that has the properties of a chemical element.
Every atom consists of:
- A nucleus in which neutrons and protons meet.
- Energy levels where electrons are located.
In other words, the atomic nucleus is the central part of the atom that is made up of protons and neutrons, while the orbitals or peripheral region is an area where electrons are found.
The neutron is an electrically neutral subatomic particle, while the proton has a positive electrical charge. Electrons have a negative charge, move around the nucleus at different energy levels and are attracted to protons, positive in the atom through electromagnetic force.
A neutral atom is one that lacks an electrical charge due to a trade-off between the number of its protons and electrons. This is, A neutral atom is characterized by having the same number of protons and neutrons.
Number of electrons in this case
A neutral atom of aluminum has 14 neutrons and 13 protons. Considering the definition of a neutral atom, aluminum has 13 electrons.
