Respuesta :

oxygen's atomic number is 8

1s22s22p4 is the electron configuration

2+2=4 4+4=8

1s22s22p4 is the electron configuration

What is Electron Configuration?

  • Electronic configuration is the arrangement of electrons around the nucleus of a particular atom or molecule.
  • Protons, neutrons, and electrons are the minuscule components that make up an atom.
  • There are the same number of protons and electrons in a neutral atom. The periodic table of elements lists that number as the element's atomic number. The quantity and location of an atom's electrons are revealed by its electronic configuration.

What is the Electronic Configuration of Oxygen?

  • The eighth element, oxygen has eight total electrons. The initial two electrons in the electron configuration for oxygen will be in the 1s orbital. The following two electrons for O are placed in the 2s orbital since 1s can only accommodate two electrons. The 2p orbital will get the final four electrons.

The O electron configuration will thus be 1s22s22p4.
