You should go to your local bank and see if they will offer you a retirement plan. Make sure you have enough of money saved away to supplement your social security money that will be coming into you.
The elements in the periodic table were named by various scientists and researchers based on their properties, origins, or characteristics, rather than by nicknames. The nicknames for some elements have been given by scientists, but they are not the official names listed in the periodic table.
The principle you're referring to is the Periodic Law. It states that the properties of elements are periodic functions of their atomic number, which is why the elements are arranged in a periodic manner in the periodic table. This organization helps identify trends and similarities in the properties of elements based on their atomic structure.
The periodic table was developed by Russian chemist Dmitri Mendeleev in 1869. He arranged the elements based on their atomic mass and chemical properties, revealing repeating patterns in their behavior. Mendeleev's periodic table is a fundamental tool in chemistry for organizing and predicting the properties of elements.
If the elements (which were discovered by his time) were organized in the increasing order of their atomic weight, they will exhibit an apparent periodicity of properties. It also had the ability to predict physical and chemical properties of some undiscovered elements.
It is named The PERIODIC TABLE. The periods being the horizontal rows The groups being the vertical columns.
Chemistry is the science primarily concerned with the periodic table, which organizes elements based on their atomic number and chemical properties. Additionally, physics and materials science utilize the periodic table to understand the behavior and interactions of elements.
The periodic table is named so because the elements are aligned in 'periods'. But it probably works the other way round. The Periodic Table has that name because it arises from Mendeleev's formulation of the Periodic Law, which he stated as "When the elements are arranged in order of increasing atomic weight, their chemical properties recur as a periodic function". The modern Periodic Law is the same except that "atomic weight" has been replaced with "atomic number".
You think probable to Dimitri Mendeleev.
Colunms are named 'Groups'. Rows are named 'Periods'.
These names are the names of chemical elements.
