Scientist believe that stellar evolution contained only hydrogen and then helium.
One. The simplest one called hydrogen. All other natural elements were derived by solar fusion and distributed by supernovas.
Other scientists were skeptical about Mendeleev's periodic table because it contained gaps for elements that had not yet been discovered and because it did not follow strict atomic weights as a basis for organization. Additionally, there was skepticism about his prediction of the properties of undiscovered elements.
Carbon, hydrogen, and oxygen.
The higher elements are forged in the center of stars. Most stars can create up to about element 6-8 on the periodic table, but any elements higher than that require a super nova.
nitrogen and oxygen
There are many elements that are contained in seawater. Some examples include magnesium, sulfur, selenium, silicon, fluorine, sodium, and chlorine.
No.
Scientists have named all known elements on the periodic table. Each element has a unique name and chemical symbol. Some elements are named after famous scientists, places, mythological figures, or distinctive characteristics.
Scientists use the periodic table to classify the elements. The elements are arranged in the table based on their atomic number, electron configuration, and chemical properties. This organization helps scientists identify patterns and relationships among the elements.
the answer is complement
Hydrogen and Oxygen
The heavy elements found in the Sun and Earth were created through nuclear fusion processes in the cores of stars. These elements play a crucial role in the formation of planets and life as we know it. Studying them helps scientists understand the origin and evolution of our solar system.
