Question: Which of the following elements is likely to have a half-filled p subshell?

Options:

Correct Answer: N

Solution:

Nitrogen (N) has the configuration 1s2 2s2 2p3, which has a half-filled p subshell.

Which of the following elements is likely to have a half-filled p subshell?

Which of the following elements is likely to have a half-filled p subshell?

Step 1: Understand what a half-filled p subshell means. A p subshell can hold a maximum of 6 electrons, and a half-filled p subshell has 3 electrons.
Step 2: Know the electron configuration of elements. The electron configuration shows how many electrons are in each subshell.
Step 3: Look at the element nitrogen (N). Its atomic number is 7, which means it has 7 electrons.
Step 4: Write the electron configuration for nitrogen: 1s2 2s2 2p3.
Step 5: Check the p subshell in nitrogen's configuration. The 2p subshell has 3 electrons, which is half of its maximum capacity (6).
Step 6: Conclude that nitrogen (N) has a half-filled p subshell.
