identify the atom 1s² 2s² 2p⁴. oxygen aluminum hydrogen argon
Answer
Answer:
Oxygen
Explanation:
Step1: Recall electron - configuration rules
The atomic number of an element is equal to the number of electrons in a neutral atom.
Step2: Calculate number of electrons
For the electron - configuration (1s^{2}2s^{2}2p^{4}), we sum the electrons in each sub - shell. (2 + 2+4=8).
Step3: Identify the element
Oxygen has an atomic number of 8, which means a neutral oxygen atom has 8 electrons. So the atom with the electron - configuration (1s^{2}2s^{2}2p^{4}) is oxygen.
