Chọn câu đúng: (1) Orbital 2s có kích thước lớn hơn orbitan 1s. (2) Orbital 2px có mức năng lượng thấp hơn orbitan 2py. (3) Orbital 2pz có xác suất phân bố e lớn nhất trên trục z. (4) Orbital 3dxy có xác suất phân bố e lớn nhất trên trục x và y. (5) Phân lớp 4f có khả năng chứa số electron nhiều nhất trong lớp e thứ 4.

Br = 80g; O = 8g; N = 4,67g

Br = 80g; O = 16g; N = 14g

Br = 40g; O = 8g; N = 4,67g

Br = 80g; O = 16g; N = 4,67g
