Atomic Structure (Bohr Model) for Oxygen (O)

Показать описание
In this video we'll look at the atomic structure and Bohr model for the Oxygen atom (O).

We’ll use a Bohr diagram to visually represent where the electrons are around the nucleus of the Oatom. Electrons are placed in energy levels in a predictable pattern. The first energy level can hold two valence electrons, and the second and third can each hold eight electrons.

Using the atomic number for Oxygen we can find the total number of electrons for the atom. We then place these in energy levels in our diagram.

The Periodic Table can also be used to determine where the electrons should go in our Bohr model. We could also write the electron configuration to show the arrangement of electrons. Electron configurations can provide a higher degree of detail about the arrangement of electrons within each energy level.

Bohr diagrams (models) are useful because the allow us to clearly see the arraignment of electrons around the nucleus. In particular, the electrons in the highest energy level are the most important since these are the electrons involved in chemical bonding. We call these valence electrons.

Thank you! I'm helping my son with a science project and this really helped. (It's been a while since I was in a science class.)

It’s 2) 6) or 1s2, 2s2, 2p4 which needs two electrons to reach the Ne electron configuration by getting 2 electrons and forming O 2- ions or sharing electrons via covalent bonds and reaching octet altho sometimes such as O2 1- they don’t reach octet and it’s called superoxide ion

Thx, i needed this cleared out for me, and now im totally getting it ty bro

Also it has p=n=e=8 in atomic state (not an ion)
8 electrons and protons and neutrons

Why do some Oxygen diagrams have no bonded Electrons
