Why did Mendeleev not consider the number of subatomic particles as a way to organize the elements?

The concept of atomic number had not yet been developed at the time of the first periodic tables, when atoms were still considered "indivisible units" and the concepts of protons, electrons, and neutrons were not yet known.

Why is magnesium different from other elements?
All elements are different from each other, that is why they are called elements. They have a different number of subatomic particles making them different.
Are elements made of large molecules?
No! Molecules are made of elements. Elements are not made from anything else except the subatomic particles protons, electrons, and neutrons.
Mendeleev's name for a column of elements?
mendeleev's name for a column of elements was groups.
Mendeleev was the first to arrange elements according to their properties in a?
Mendeleev arranged the elements according to their atomic weight and valence.
What matter is in an element?
The only matter in a stable element is at least one of each of the two stable electrically charged subatomic particles, protons and electrons, and except for an atom of the isotope hydrogen-1, at least one neutron, the uncharged stable subatomic particle. The numbers of protons and electrons must be the same. Artificial elements may contain other subatomic particles such as positrons. (The subatomic particles themselves are considered to be composed of quarks, which could be called sub-subatomic particles, but quarks are not usually considered to be matter since they can not exist in isolation for more than very small fractions of a second.)
The subatomic particles or units that govern potential chemical reactions among elements are?
The subatomic particles that govern potential chemical reactions among elements are known as electrons.
What are the subatomic particles of astatine?
As for all other elements: neutrons, protons and electrons.
What are the subatomic particles of manganese?
Subatomic particles are the same for all substances that exist everwhere. So to ask "What are the subatomic particles of manganese?" is really not a good question. Manganese is an element. And like all elements, it is made up of atoms. Atoms are made up of.......subatomic particles! (Moledule)(Cation)(Ion)===>Element====>Atom====>Subatomic particle The are three basic subatomic particles: protons, electrons and neutrons. If you really want to get anal about it, you can also find out what neutrons are made up of. I would tell you, but I forgot!
What are the three types of atoms that make up an element?
An atom and an element are synonyms. Rather, subatomic particles make up atoms (and elements). The three types of subatomic particles are neutrons, protons, and electrons.
Why is magnesium different from other elements?
All elements are different from each other, that is why they are called elements. They have a different number of subatomic particles making them different.
Are elements made of large molecules?
No! Molecules are made of elements. Elements are not made from anything else except the subatomic particles protons, electrons, and neutrons.
What subatomic particles are in an isotope of zirconium?
All the isotopes of chemical elements contain protons, neutrons and electrons.
Shared when elements combine to form a compound?
Electrons are shared when elements combine to form molecules. These are subatomic particles with a negative elementary electric charge.
Is oxygen one atom?
Elements (oxygen being one of them) are composed of subatomic particles; that is, protons, neutrons, and electrons. Subatomic particles make up atoms (hence "sub"atomic). Therefore, it is reasonable to say that oxygen is an atom.
Mendeleev's name for a column of elements?
mendeleev's name for a column of elements was groups.
Why were the elements important to Mendeleev?
Chemical elements arrangement was the object of study for Mendeleev.
How can be defined the elements?
It can not be broken down any further unless you electromagnetically separate the nucleus and electrons, which creates subatomic particles.
