halogens
noble gases Helium has 2 valence electrons, whereas the rest have 8.
The electron configuration of copper is 1s22s22p63s23p63d104s1.
The outer electron configuration for oxygen is 2s^2 2p^4. This means that oxygen has 6 outer electrons in its valence shell.
The outer electron configuration for germanium is 4s^2 4p^2. Germanium has 4 valence electrons in the outermost shell.
im guessing you mean valence shell electron configuration that would be: 5s^2 4d^10 5p^6
The noble gas that has the same electron configuration as magnesium ion (Mg²⁺) is neon (Ne). When magnesium loses two electrons to form Mg²⁺, it has the electron configuration of 1s² 2s² 2p⁶, which is identical to that of neon. Thus, both Mg²⁺ and Ne have a complete octet in their outer shell.
no it only has 1 electron in the outer shell
The electron configuration of boron is 1s2 2s2 2p1. When boron becomes an ion, it typically loses its outer electron to achieve a stable electron configuration. Therefore, the electron configuration of a boron ion is typically 1s2 2s2.
The electron configuration of rutherfordium is: [Rn] 5f14 6d2 7s2.
No, calcium (Ca) has a unique electron configuration due to its atomic number and position in the periodic table. Its electron arrangement is 1s2 2s2 2p6 3s2 3p6 4s2. While there are other elements with similar electron configurations, none are identical to calcium.
The short form electron configuration for fluorine is [He] 2s2 2p5. The [He] represents the electron configuration of helium, which has 2 electrons in its outer shell.
Valence electron configuration of zinc, abbreviated. [Ar] 4s2 3d10 Zinc's oxidation state is 2, so that 4s2 represents the valance electrons though they are at a lower energy level and the 3d10 gives you the full outer electron configuration.
