Blended learning offers numerous benefits that enhance the educational experience for both students and instructors. By combining traditional face-to-face teaching with online learning, it provides greater flexibility in how and when students engage with course materials. This approach caters to different learning styles, allowing students to learn at their own pace, review content as needed, and access resources outside of classroom hours. It also promotes active learning, encouraging students to take responsibility for their education. Additionally, blended learning fosters greater interaction and collaboration, as online platforms can facilitate discussions, group projects, and peer feedback. For instructors, it allows more efficient use of classroom time, focusing on engaging, interactive activities, while administrative tasks like grading and feedback can be streamlined through digital tools. Ultimately, blended learning creates a more personalized, accessible, and effective learning environment.

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.
