When you fill an orbital the electrons must spin in opposite directions. This results in no two electrons having the same quantum number, a result defined as the Pauli Exclusion Principle. You can have 2 electrons in an orbital. Note that 2py 2px and 2pz are three different orbitals.
There are 5 electrons in the d orbital of an Os3+ ion.
There are two electrons at most in an orbital, further, they have spins in opposed directions.
6 electrons
There are 5 d orbitals which hold 2 electrons each. Thus, 10 electrons are needed to completely fill them.

It needs to lose one electron so that it can have 8 electrons in its outer orbital
Carbon has four valence electrons, so it will need four more electrons to fill its outer shell.

4 to fill the 2p shell
4 to fill the 2p shell
The S orbital contains a maximum of two electrons
I'm thinking that is would be alot
