What is the composition of the aluminum atom?
L’aluminum atom is made up of 13 protons, 14 neutrons and 13 electrons.
Why is aluminum a poor metal?
L’aluminum is a chemical element listed in the periodic table (also called the Mendeleev table). It belongs to the family of poor metals (sometimes called post-transitional or post-transitional), because the properties of these metals are less pronounced than those of the other families of metals.

What is the etymology of aluminium?
First named aluminum by its discoverer, the Englishman Sir Humphry Davy, it then took the name aluminum on the model of the word English alumina (“alumina, land of alum”), then, to enter the group of metals in “-ium” (suffix designating a metal) such as sodium and potassium, it took the name ofaluminum.

What are the three constituent particles of the atom?
Yet theatom is composed of particles even smaller: it is made up of electrons particles negatively charged) and a nucleus, which is itself composed of protons ( particles positively charged) and neutrons (which have no electrical charge).
Who created the atom?
Democritus The philosophical origins of the notion ofatom It is attributed to Empedocles, Democritus, Leucippus, then Epicurus. Their conceptions of an atomic structure of matter did not proceed from observations or scientific experiments in the current sense, but from intuitions.
