What is zero.
Which element has the same number of valence electrons as Carbon,

K
Potassium
Why does water form as H2O molecules instead of HO molecules?
Because an atom of Oxygen has space in its valence shell for two more electrons, and each Hydrogen atom has one valence electron.

Although any atom can ionize if enough energy is applied, some are very unlikely. Why is Krypton unlikely to form an ion?
Krypton is one of the Noble Gasses on the far right side of the Periodic Table, and like Helium, Neon, and Argon, has a full valence shell of 8 electrons. It is already very stable and has little reason to gain or lose any electrons.
This element is named after the scientist who first came up with the idea of the Periodic Table of Elements.
