Bohr atomic model depictions have a positively charged center, usually represented by the number of positive charge carriers (i.e. protons) surrounded by a circle [for Hydrogen, this would be (1+) ]. This positively charged center is the nucleus of the atom, where most of the mass resides
Around the nucleus, electron orbits are depicted as circles. The first orbit can only hold two electrons, the second can hold eight, and the third can hold 18 (although the Bohr model becomes less and less useful as the number of electron orbitals increases, so Bohr atomic models with more than 10 protons are uncommon).
If the atom depicted has an overall charge, the entire model is surrounded by rectangular brackets (These things ==> [ ]), and the overall charge is shown outside, usually on the upper right.
For neutral oxygen, the Bohr model would have a circle with 8+ inside (because oxygen is atomic number eight, and has eight protons), two electrons in the first orbit, and six in the second orbit to make eight.
For the oxide ion (O2-), the Bohr model would have the same circle with 8+ inside (because oxygen ions still have oxygen nuclei), two electrons in the first orbit, and eight in the second orbit (to fill the orbit, which is usually energetically favorable). Since there are more electrons than protons, the whole model is surrounded by square brackets, and 2- is written on the upper right to denote that the atom has two fundamental units of negative charge (i.e. two fewer protons than electrons)

RafaThe electron configuration for oxygen is 1s^2 2s^2 2p^4. This means there are 8 electrons in total, with 2 in the 1s orbital, 2 in the 2s orbital, and 4 in the 2p orbital. You can represent this configuration by drawing 2 electrons in the first energy level and 6 electrons in the second energy level, with 4 paired in the 2p sublevel.

What is the electron configuration of oxygen?
The electron configuration of oxygen (atomic number 8) is 1s2 2s2 2p4The noble gas form is [He] 2s22p41s2 2s2 2p4
What ions are formed by oxygen and fluorine?
Oxygen tends to form O^2- ions, gaining two electrons to achieve a stable electron configuration. Fluorine tends to form F^- ions, gaining one electron to achieve an electron configuration similar to a noble gas.
What is the shorthand electron configuration of magnesium?
The shorthand electron configuration of magnesium is [Ne]3s².
How would you draw the electron configuration of silicon?
The electron configuration of silicon is 1s2 2s2 2p6 3s2 3p2. You can represent this in shorthand notation by writing [Ne] 3s2 3p2, which indicates that silicon's configuration is the same as neon's configuration followed by the outermost electron sublevels of 3s2 3p2.
What is the longhand electron configuration for Sulfur?
The longhand electron configuration for Sulfur is 1s2 2s2 2p6 3s2 3p4.
