- P (Z = 15): 1s22s22p63s23p3 Þ P có 5 electron hóa trị cần thêm 3 electron để đạt octet.

- H (Z = 1): 1s1 Þ H có 1 electron hóa trị cần thêm 1 electron để đạt octet.

- Khi hình thành liên kết, P góp chung 3 electron với 3 electron của 3 H ⇒ Trong PH3, xung quanh P có 8 electron giống khí hiếm Ar còn 3 H đều có 2 electron giống khí hiếm He.

- Vận dụng quy tắc octet để giải thích sự tạo thành liên kết hóa học trong phân tử phosphine (PH3)

A Night to Remember: The Sounds of Summer Music Fest 2024

Last weekend, I attended the Sounds of Summer Music Fest at the Riverside Park Amphitheater, held on a warm Saturday evening. I went with a group of friends, eager to escape the hustle and dive into the rhythm of live music. The atmosphere was electric-people of all ages gathered on picnic blankets, some dancing, others simply enjoying the music with drinks in hand. We explored the various food stalls before settling in front of the main stage.As the sun set, the headliners took the stage, and the crowd erupted in cheers. The energy was contagious! The mix of indie, electronic, and classic rock kept us dancing late into the night. I left feeling uplifted, already looking forward to next year’s event.
