The outer level of a noble gas is..?

Question

1) empty
2) filled
3) half-filled

Thanks so much everyone!

Answer 1

empty and filled

It can be both empty or filled dependign on which shell you consider to be the outer shell. The outer shell can be the outermost shell to contain electrons, which is filled. Or it can be the next outermost shell, which is empty in an atom but could become the valence shell in an ion.

Answer 2

2. Filled. This makes the noble gases the most inert elements of all. They have almost no tendency to give, take, or share electrons. They do form clathrates, physical enclosures of an atom of a noble gas enclosed in a "cage" or "lattice" of other atoms. In order for the noble gas to be released, the chemical bonds holding the surrounding atoms have to be broken, but clathrates are not chemical compounds of the noble gas.

Electron arrangements in outer shell of noble gases:

Helium-=-------------2
Neon------------------8
Argon-----------------8
Krypton--------------18
Xenon----------------18
Radon----------------32

It is possible, just possible, that compounds of Radon could be formed, as the inertness of these elements decreases as the atomic number increases, and even more likely that compounds of eka-Radon would exist. Eka is the Sanskrit for "one" and eka-Radon would be the element "one below" Radon in the periodic table. It would be a gas with a higher melting and boiling point than the other members of the family probably radioactive,although that is open to speculation, and with a slight tendency to form covalent compounds.

Answer 3

The outermost shell (also called the valence shell) of a noble gas is filled with electrons. That's the reason noble gases do not react, because they neither need to lose nor gain electrons. They have a full valence shell.

Answer 5

2) filled...the octet rule
