Trong phân tử phosphine (PH₃), phosphorus chia sẻ 3 electron của mình với 3 nguyên tử hydro. Mỗi hydro nhận được 1 electron từ phosphorus, hoàn thành cấu hình 2 electron (giống helium). Vì vậy, phân tử PH₃ có 3 liên kết đơn giữa phosphorus và hydrogen, và phosphorus không tuân theo hoàn toàn quy tắc octet (vì có 8 electron ở lớp ngoài nhưng không phải là cấu hình hoàn chỉnh với 8 electron của một nguyên tử thuộc nhóm VA).

Recently, I had the opportunity to attend an unforgettable music event that left me completely mesmerized. The lineup was incredibly eclectic, featuring a diverse range of performers and genres that catered to every musical taste. The enthusiastic crowd created a dynamic atmosphere filled with vibrant energy and a communal spirit. The performances were nothing short of awe-inspiring, leaving a lasting impression on everyone present. The artists not only showcased their musical talents but also treated us to captivating visuals and stage setups. Socializing with fellow music enthusiasts added an extra layer of enjoyment to the overall experience. It was more than just a concert; it was a celebration of music, bringing people together in a way that only live performances can.
