The shell model explains the organization of the periodic table.

The elements in the first period have electrons in the first shell; the elements in the second period have electrons in the first two shells; the elements in the third period have electrons in the first three shells; and so on.

Why is hydrogen in the perodic table?

Hydrogen is in the periodic table because it is an element, and all elements are in the periodic table.


How many electrons are in the outer shell of phosphorus?

There are 5, it is in group 5 on the periodic table of the elements


What family does nitrogen belongs to?

On the periodic table, the family nitrogen belongs to is Group Vb. In their outer electronic shell, each of the elements within this group have five electrons.


How many electrons does aluuminum have in the second shell?

This is a chemical element. You can find the how many electron in a single atom by using a periodic table.


Why is lathanide and actinide not part of the periodic table?

Besides the periodic table, an electron chart of the elements exists. The periodic table shows the broad outline. The electron chart goes into greater detail. The periodic table lists elements according to electrons in their outer shell. As elements get more massive they get more protons and electrons. Each time they add a proton, they jump one notch in the periodic table. When they add the electron, it is a valence electron and it affects the chemical properties. There comes a point when elements start adding electrons when the electrons are not added to the outer shell with the other electrons in the valence shell. The chemical properties do not change as the elements get heavier. It is extremely difficult to use chemistry to separate the elements in that group. If you had an electron chart, you would see the electrons followed a different pattern. That is why the lanthanides and actinides are set apart from the other elements on the periodic table. According to their chemical properties, they would all need to be put into one box.

Why is Mendeleev periodic table considered a scientific model?

it could be used to explain the behavior of all of the elements.


How does the bohr model relate to the periodic table?

The Bohr model helped explain the arrangement of electrons in an atom's energy levels. This model laid the groundwork for understanding the structure of the periodic table by showing that elements with similar electron configurations tend to exhibit similar chemical properties and are grouped together in the periodic table.

What is unreactive and has a full shell on the periodic table?

A noble gas, such as helium or neon, is unreactive and has a full outer electron shell on the periodic table. This full outer shell makes them stable and less likely to form chemical bonds with other elements.


The organization of the periodic table is based on what?

Why is Mendeleev's periodic table considered a viable scientific model?

Mendeleev's periodic table is considered a viable scientific model because it successfully organized the elements based on their properties and predicted the existence and properties of yet-to-be-discovered elements. It laid the foundation for the modern periodic table and influenced the development of our understanding of the elements and their relationships.
