Question

what is the next atomic orbital in the series 1s, 2s, 2p, 3s, 3p?
3f
3d
2d
4s
question 19
0.4 pts
the letter \p\ in the symbol 4p3 indicates the____
speed of an electron
spin of an electron
principle energy level
orbital type

Explanation:

Question 1

The order of filling atomic orbitals follows the Aufbau principle. After 3p, the next - lower energy orbital is 4s. Also, 3f and 2d do not exist as the first f - orbitals start at n = 4 and the first d - orbitals start at n = 3.

In the electron - configuration notation like 4p3, the number (4) represents the principal energy level, and the letter (p) represents the orbital type (s, p, d, f). The number 3 represents the number of electrons in the p - orbital.

Answer:

D. 4s
