Step 1
To answer this question, we need to understand the concept of electronic configuration and subshells.

Electrons are arranged in shells and subshells around an atom. The subshells are denoted by the letters s, p, d, and f, and they can hold a maximum number of electrons as follows: - s subshell: 2 electrons - p subshell: 6 electrons - d subshell: 10 electrons - f subshell: 14 electrons The filling of electrons in subshells follows the Aufbau principle, which states that electrons occupy the lowest available energy levels. The order of filling subshells is s before p before d before f. A cation is a positively charged ion formed by removing electrons from a neutral atom. In this case, we want to find out which subshell the electron is removed from to form a + 1 cation. Let's consider a few examples to illustrate the concept:

Step 2

Sodium (Na) has the electronic configuration [Ne]3s¹, where [Ne] represents the noble gas neon core. To form a + 1 cation, we need to remove one electron from the 3s subshell.

Final Answer

An electron is removed from the s subshell to form a + 1 cation.
