QuestionWrite the electron configuration for a sodium ion (Na).
Studdy Solution
STEP 1
Assumptions1. We are dealing with a sodium cation, which means it has lost one electron.
. The atomic number of sodium (Na) is11, which means a neutral sodium atom has11 electrons.
3. The charge of the sodium cation is +1, which means it has lost one electron and now has10 electrons.
4. The electron configuration is written in the format of increasing energy levels.
STEP 2
First, we need to understand the electron configuration for a neutral sodium atom. The atomic number of sodium is11, so a neutral sodium atom has11 electrons.The electron configuration for a neutral sodium atom is
STEP 3
Now, we need to consider the charge of the sodium cation, which is +1. This means the sodium atom has lost one electron to become a cation.
STEP 4
The electron that is lost is the one in the highest energy level. In the case of sodium, this is the electron in the3s orbital.
STEP 5
So, the electron configuration for a sodium cation (Na+) with a charge of +1 is1s^22s^22p^This means the sodium cation has10 electrons, distributed as follows2 in the1s orbital,2 in the2s orbital, and in the2p orbital.
