The number of protons in the nucleus or the number of electrons surrounding the nucleus. This number is also called atomic number of the element.
some are in latin, some in english, the periodic table of the elements is all different languages.
The atomic number that sodium has in periodic table is 11 and valency is 1. The periodic table is a kind of table that was invented for the better study of elements and other types of compound. It makes the systematic study of elements.
Dmitri Mendeleev organized the elements by increasing atomic mass and grouped elements with similar properties together, leaving gaps for undiscovered elements. This contrasted with other chemists who arranged elements by atomic weight alone or in alphabetical order without considering their properties. Mendeleev's periodic table accurately predicted the properties of missing elements and laid the foundation for the modern periodic table.
Its made from different elements
If there are 109 different elements, there must be 109 different atomic numbers since each element has a unique atomic number that distinguishes it from other elements on the periodic table.
Noble gases are unique because they are very stable and do not easily react with other elements to form compounds. They have a full outer electron shell, making them very unreactive and inert. This stability sets them apart from other elements in the periodic table.
None are derived from another.
all non-metals and are found in the earth's crust
the periodic table
If the periodic table was rearranged based on a different organizing principle, the elements would be grouped together in a different way than they are currently. This could potentially change our understanding of the relationships between elements and how they interact with each other.
The periodic table of elements
Noble gases actually have the most stable electronic configurations in the periodic table due to having a full outer shell of electrons. This full octet makes them less likely to react with other elements, earning them the name "noble gases."
