Who designed the original periodic table?
Dmitri Mendeleev is credited with designing the original periodic table in 1869. He organized the elements based on their atomic mass and chemical properties, which laid the foundation for the modern periodic table.
Who contributed to the periodic table?
The periodic table was created by Russian chemist Dmitri Mendeleev in 1869. Mendeleev organized the elements based on their properties and predicted the existence of undiscovered elements. Over time, other scientists like Henry Moseley made contributions to improve and expand upon the periodic table.
Why are elements put into families?
Elements are organized into families on the periodic table based on their similar chemical properties. Elements in the same family have the same number of valence electrons, which determines their reactivity and chemical behavior. This organization helps scientists predict the properties of unknown elements based on their location in the periodic table.
