QuestionWhat is the chemical symbol for the ion with electron configuration ?
Studdy Solution
STEP 1
Assumptions1. The electron configuration given is for an ion.
. The electron configuration notation follows the standard format, where the superscripts represent the number of electrons in each subshell.
3. The symbol [He] represents the electron configuration of a helium atom, which is1s².
STEP 2
First, we need to understand the electron configuration notation. The notation [He] represents the electron configuration of a helium atom, which is1s². This means that the ion has the same electron configuration as helium, plus the additional electrons indicated in the given configuration.
STEP 3
The given electron configuration is [He]2s²2p⁶. This means that the ion has2 electrons in the2s subshell and6 electrons in the2p subshell, in addition to the2 electrons in the1s subshell represented by [He].
STEP 4
Now, we can add up the number of electrons in each subshell to find the total number of electrons in the ion.
STEP 5
Calculate the total number of electrons.
STEP 6
The atomic number of an element is equal to the number of electrons in a neutral atom of that element. Therefore, the ion with10 electrons in its neutral state corresponds to the element with the atomic number10.
STEP 7
Looking at the periodic table, the element with the atomic number10 is Neon (Ne).
The chemical symbol for the ion is Ne.
