WebJan 30, 2024 · In the Bohr model, electrons are pictured as traveling in circles at different shells, depending on which element you have. Figure 2 contrast the Bohr diagrams for lithium, fluorine and aluminum atoms. The shell closest to the nucleus is called the K shell, next is the L shell, next is the M shell. WebThin- shell structures (also called plate and shell structures) are lightweight constructions using shell elements. These elements, typically curved, are assembled to make large …

WebDec 29, 2024 · According to the Bohr diagram of Helium, the outer shell is K-shell which contains 2 valence electrons. Properties of Helium It is a non-toxic, colorless, odorless, and tasteless gas. It belongs to the noble gas group in the periodic table. It has a boiling point of −268.928 °C and a melting point of −272.20 °C. It has a zero oxidation state. WebValence electrons are the electrons in the outermost shell, or energy level, of an atom. For example, oxygen has six valence electrons, two in the 2s subshell and four in the 2p subshell. We can write the configuration of oxygen's valence electrons as 2s²2p⁴. Created by Sal Khan.
