Question

using the periodic table to trace a stepwise path from hydrogen to the element below and give the electron - configuration by specifying each of the periods (row), block (subshell), and the number of electrons (steps - superscripted). what is the electron configuration for n? 1s²2s²2p³ 1s²2s²2p⁶3s¹ 1s²2s²2p⁶3s²3p¹ 1s²2s²2p⁴ question 19 1 pts using the periodic table below, trace a stepwise path from hydrogen to the element below and give the electron - configuration by specifying each of the periods (row), block (subshell), and the number of electrons (steps - superscripted). what is the electron configuration for ti? 1s²2s²2p⁶3s²3p⁶4s²3d¹⁰4p¹ 1s²2s²2p⁶3s²3p⁶4s²3d² 1s²2s²2p⁶3s²3p⁶4s² 1s²2s²2p⁶3s²3p⁶4s²3d¹

Explanation:

Step1: Recall electron - filling rules

Electrons fill orbitals in the order of increasing energy: 1s < 2s < 2p < 3s < 3p < 4s < 3d < 4p and so on. The s - subshell can hold a maximum of 2 electrons, the p - subshell can hold a maximum of 6 electrons, the d - subshell can hold a maximum of 10 electrons.

Step2: Determine electron configuration for N

Nitrogen (N) has an atomic number of 7. Electrons fill as follows: 2 electrons in the 1s orbital (1s²), 2 electrons in the 2s orbital (2s²), and the remaining 3 electrons in the 2p orbital (2p³). So the electron - configuration of N is 1s²2s²2p³.

Step3: Determine electron configuration for Ti

Titanium (Ti) has an atomic number of 22. Electrons fill: 2 in 1s (1s²), 2 in 2s (2s²), 6 in 2p (2p⁶), 2 in 3s (3s²), 6 in 3p (3p⁶), 2 in 4s (4s²), and 2 in 3d (3d²). So the electron - configuration of Ti is 1s²2s²2p⁶3s²3p⁶4s²3d².

Answer:

For N: 1s²2s²2p³
For Ti: 1s²2s²2p⁶3s²3p⁶4s²3d²
