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

My sister and I attended the F5 tour at the National Stadium last night. I could sum up the concert in one word, INCREDIBLE. We found our way up to our seats after having a light meal and stood in a queue at the gate of the stadium for 45 minutes. When the curtain was raised to reveal the F5 band, the entire stadium went absolutely crazy. I was thrilled by every one of their performances. There was so much emotion in many of their songs, and the way they performed was so terrific. This was such a wonderful experience, a night that I'll never forget. I'm so grateful to have been able to have that experience
