91 Pa : [Rn] 5f 2 (3 H 4) 6d 7s 2 Gallium is not a biologically significant element. Gallium was discovered in 1875 by Paul Emile Lecoq de Boisbaudran.
The superscripts represent the electrons present in each region of the periodic table. The stable isotopes are only two, gallium-69 and gallium-71. The electron configuration for gallium is 1s 2 2s 2 2p 6 3s 2 3p 6 3d 10 4s 2 4p 1, according to the Thomas Jefferson National Accelerator Facility Office of Science Education. It is in the Boron family (group 13) and in period 4.
The upper right side shows the number … Gallium has one of the longest liquid temperature ranges of any metal, with a low vapor pressure even at high temperatures. This website is also cited in the CRC Handbook as source of Section 1, subsection Electron Configuration of Neutral Atoms in the Ground State. Hydrogen is a chemical element with atomic number 1 which means there are 1 protons and 1 electrons in the atomic structure.The chemical symbol for Hydrogen is H. With a standard atomic weight of circa 1.008, hydrogen is the lightest element on the periodic table.

The last electron is in the 4th period, in the p region and the first electron in that region. Comprehensive information for the element Gallium - Ga is provided by this page including scores of properties, element names in many languages, most known nuclides and … Properties: Gallium has a melting point of 29.78°C, boiling point of 2403°C, specific gravity of 5.904 (29.6°C), specific gravity of 6.095 (29.8°C, liguid), with a valence of 2 or 3. Gallium is a metallic element with an atomic weight of 69.723 amu. The difference between the neutron number and the atomic number is known as the neutron excess : D = N – Z = A – 2Z. The chemical symbol for Gallium is Ga.. Atomic Mass of Gallium. Classified as a post-transition metal, Gallium is a solid at room temperature. Electronic configuration: 1s 2 2s 2 2p 6 3s 2 3p 6 3d 10 4s 2 4p 1 >> Back to key information about the elementBack to key information about the element 585 reads; Gallium Element: Gallium is an element in the thirteenth group and fourth period of periodic table and it has the symbol Ga and atomic number 31. The final ring or shell of electrons contains the typical number of valence electrons for an atom of that element. Boisbaudran named his newly discovered element after himself, deriving from the Latin word, “Gallia,” which means “Gaul.”
Neutron number is rarely written explicitly in nuclide symbol notation, but … Neutron number plus atomic number equals atomic mass number: N+Z=A.
