An orbital is made up of 2 electrons and any orbital which has only 1 electron is considered unpaired.For example: Carbon has atomic number 6 so the electronic configuration is: 1s22s22p2 so now there are only 2 electrons in the p-orbital; so only two of the three p-orbitals are incompletely filled hence the number of valence or unpaired electrons is 2.
