A sponge is an item that can be completely filled with moisture due to its porous nature.
the one that is completely filled
Three completely filled orbitals.
The outer shell is completely filled.
Elements are stable when they have completely filled (or half filled) orbitals.
full
"Completely filled" means that a container or space has been packed to its maximum capacity without any empty spaces remaining.
Argon has completely filled M shell (or 3p orbital)
Its outer shell is filled with electrons.
Nitrogen (N) is atomic number 7, so has 7 electrons in the ground state. The configuration is1s2 2s2 2p3. From this, one can see that the 1s is full, as is the 2s. So, the number of completely filled orbitals is TWO.
There are two completely filled orbitals in this atom: the 1s orbital with 2 electrons and the 2p orbitals with 6 electrons. The 2s orbital and 3s orbital are not completely filled.
Noble gases have completely filled outer sublevels. For example, helium has a filled 1s sublevel, neon has filled 2s and 2p sublevels, and argon has filled 3s and 3p sublevels.
