WebMar 22, 2024 · a molecule composed of two chlorine atoms; a molecule composed of a hydrogen atom and a bromine atom; Solution. Chlorine has the same valence shell electron configuration as fluorine, so the Lewis diagram for a molecule composed of two chlorine atoms is similar to the one for fluorine: WebUnformatted text preview: Filled (or empty ) shells are more stable than partially filled shells. Atoms tend to _ gain (or lose ) electrons to fill (or empty) their valence shells. . Electronegativity- the amount of attraction for electrons an atom has.

In chemistry and atomic physics, an electron shell may be thought of as an orbit followed by electrons around an atom's nucleus. The closest shell to the nucleus is called the "1 shell" (also called the "K shell"), followed by the "2 shell" (or "L shell"), then the "3 shell" (or "M shell"), and so on farther and farther from the nucleus. The shells correspond to the principal quantum numbers (n = 1, 2, 3, 4 ...) or are labeled alphabetically with the letters used in X-ray notation (K, L, M, ...). A useful gui… WebDuring the formation of a bond, the last shell of chlorine receives an electron and turns into a chloride ion (Cl – ). In this case, the chlorine atom carries a negative charge. Cl + e – → Cl – Here, the electron configuration of chloride ion (Cl –) is 1s 2 2s 2 2p 6 3s 2 3p 6.
