Each atom is left with a what outer shell?
Each atom is left with a full outer shell of electrons, which makes them stable and less likely to form bonds with other atoms.
Why is a filled valence shell often called an octet?
A filled valence shell often has 8 electrons, which is called an octet. This configuration is considered stable because it mimics the electron configuration of noble gases, which have full valence shells.
What is the outer-most shell of an atom called?
The outer-most shell of an atom is called the valence shell. It is involved in forming chemical bonds with other atoms.
Does Sodium have a full outer valence shell?
Sodium does not have a full outer valence shell. It has one electron in its outermost shell, which makes it very reactive and likely to lose that electron to achieve stability.
How many full orbitals and half-full orbitals are there in valence shell of krypton?
Krypton is a noble gas and hence has stable electronic configuration. Its valence shell configuration is 4s2 4p6 . Therefore, it has 1-s and 3-p full orbitals in its valence shell.
