It depends what type of orbital these two electrons occupy. But there would be one arrow going up and one arrow going down to show two electrons in the same orbital.
Most oxygen molecules contain two atoms, which we breath O2. If we breath pure oxygen (one atom) our lungs would burn. Three molecules of oxygen is the ozone which is unstable and converts back to O2.
1s2 2s2 2p4 Meaning 2 electrons in the 1s orbital/shell, 2 electrons in the 2s orbital & 4 electrons in the 2p. So both 1s & 2s orbitals are full, the 2p orbital is only partly filled as it can hold 6 electrons.
There are two electrons at most in an orbital, further, they have spins in opposed directions.
There are many types of rules for electron configuration. Look at the Aufbau principle and Hund's rules.In each orbital there is a maximum of two electrons.In a "s" orbital, there are two electrons.In a "p" orbital, there are three sub-orbitals, each containing two electrons. (Thus containing 6 electrons)In a "d" orbital, there are five sub-orbitals, each containing two electrons. (Thus containing 10 electrons)In a "f" orbital, there are seven sub-orbitals, each containing two electrons. (Thus containing 14 electrons)Look at the Aufbau diagram I linked below.The coefficient represents the orbital. Do not use mathematics to try to solve the configurations.1s2 2s2 2p6 : Neon's Electron ConfigurationThe letter following the coefficient describes which type of orbital it is, being s,p,d, or f.The superscript denotes the number of electrons it contains. If you add 2, 2, and 6, you would get 10, Neon's atomic number.
Electrons start pairing in the 1s orbital. A 1s orbital can take two electrons, represented by 1s2.

If you add 2, 2, and 6, you would get 10, Neon's atomic number.Electron configurations become stable when they are neutrally charged.i.e Li: 1s2 2s1This is a stable electron configuration. However, if you lose that one electron,Li: 1s2It become a positively charged ion, called a cation.
In any orbital the maximum number of electrons is 2 of opposite spin. The following is a list of the different types of orbitals and the maximum nuber of electrons each type can contain. s-orbitals: one orbital, containing 2 electrons p-orbitals: three (px, py, pz) containing 6 in total d-orbitals: five, containing 10 f-orbitals: seven containing 14
Be (beryllium) has four electrons total: the first orbital, the 1s orbital, has two, which leaves two electrons in the outer shell.
The S orbital contains a maximum of two electrons
(Ne)3s2 3p2 is an electron configuration notation that describes the arrangement of electrons in an atom or ion. The (Ne) in parentheses indicates that the electron configuration begins with the noble gas neon, which has the electron configuration 1s2 2s2 2p6. The 3s2 indicates that the next two electrons are in the 3s orbital, and the 3p2 indicates that the final two electrons are in two of the three 3p orbitals. The superscript 2 for each orbital indicates that there are two electrons in each orbital, following the Pauli exclusion principle, which states that no two electrons in an atom can have the same set of quantum numbers. The "sp" notation is not commonly used in electron configuration notation. It is more commonly used in hybridization notation to describe the hybridization of atomic orbitals in a molecule. In that context, "sp2" would indicate that one s orbital and two p orbitals have combined to form three hybrid orbitals, which are used to form sigma bonds with other atoms.
An s orbital can have a maximum of two electrons.
A single orbital can hold up to two electrons.
1s2 2s2 2p4 Meaning 2 electrons in the 1s orbital/shell, 2 electrons in the 2s orbital & 4 electrons in the 2p. So both 1s & 2s orbitals are full, the 2p orbital is only partly filled as it can hold 6 electrons.
The are two electrons in the 3s orbital of magnesium (Mg.)
