all elements after uranium (atomic number 92) are radioactive.
All except neon and helium
There are 92 naturally occurring elements in the periodic table of the elements. Each element differs from the next by the number of protons within its nucleus. Hydrogen has one proton. Helium as two. Next comes Lithium, Beryllium, Boron, Carbon, Nitrogen, Oxygen, Flourine, and Neon, rounding out the first ten. Google "periodic table" for a complete list.
Lithium
Hydrogen, oxygen, carbon,Argon, nitrogen, sodium, chlorine, fluorine, calcium, and sulphur Those are some of the more important elements.
The periodic table is unlikely to change significantly in the next ten years as the fundamental properties of elements remain constant. However, new elements may be discovered and added to the table if they meet the criteria set by the International Union of Pure and Applied Chemistry (IUPAC).
There are ten elements in each transition series of the periodic table because each series corresponds to the filling of the d-orbitals, which can hold a maximum of ten electrons. The transition metals are defined by the presence of electrons in these d-orbitals, and the elements in each series represent the sequential addition of electrons to these orbitals. Consequently, each transition series encompasses ten elements, from scandium (Sc) to zinc (Zn) in the first series, for example.
The elements that honor Dmitri Mendeleev, the father of the periodic table, are Mendelevium, Dubnium, Hassium, Bohrium, Meitnerium, Roentgenium, Copernicium, Flerovium, Livermorium, and Oganesson.
Helium (element 2 He) and Neon (element 10 Ne) are unlikely to form molecules because they are noble gasses and thus unreactive.
Different number of elements: Each periodic table contains the same elements, but the number of elements included may vary depending on the table's design and purpose. Arrangement: Various periodic tables may organize elements differently, such as by atomic number, electron configuration, or properties. Color-coding: Some periodic tables use different color-coding schemes to highlight specific trends or groupings of elements. Additional information: Some periodic tables may include extra information alongside the basic elements, such as isotopes, electron affinities, or more detailed atomic properties.
