What element is a noble gas that does not have eight electrons in its outer shell?
Helium is the element in the noble geses family that does not have an octet. Helium is the element in the noble geses family that does not have an octet.
How many electrons does it take to fill the outer shell to become like a noble gas?
For most elements, a complete outer shell, like that of a noble gas, has eight electrons. There are exceptions. Helium, which is the most noble of the noble gases, has only two electrons in its outer shell. A few other light elements only need two (and hydrogen can also exist with no electrons at all, in the form of a naked proton, which is also a form of completion for the outer shell).
How many electrons does a chemically stable atom have in its outer energy level?
8 electrons
How many electrons are in the outer shell of a noble gas with an atomic mass greater than three?
Noble gases have a full outer shell of electrons, which makes them stable and unreactive. For noble gases, the outer shell typically contains eight electrons, following the octet rule. This applies to all noble gases with atomic masses greater than three, such as neon, argon, krypton, xenon, and radon. Therefore, a noble gas with an atomic mass greater than three has eight electrons in its outer shell.
Does group 2A gain electrons or lose electrons in order to achieve a noble gas configuration?
loses 2 electrons to achieve a noble gas configuration
What element is the only noble gas that does not have eight electrons in its outer shell?
Helium is the only noble gas that does not have eight electrons in its outer shell. It has only two electrons in its outer shell.
What element is a noble gas that does not have eight electrons in its outer shell?
Helium is the element in the noble geses family that does not have an octet. Helium is the element in the noble geses family that does not have an octet.
A gas that has a stable number of electrons in the outer energy level?
Noble gas
What does not have a noble gas configuration Na Rb O2 Br Ca Al3 S2?
Na, Rb, Al3+, and S2- do not have a noble gas configuration as they do not have the complete outer shell of electrons like a noble gas. O2, Br, Ca, and O2- have noble gas configurations as they either have a complete outer shell of electrons or have gained/lost electrons to achieve a stable noble gas configuration.
Why are noble gas nonreactive?
Having the outer shell of electrons filled noble gases are very stable.
Does oxygen react with noble gases?
No! oxygen does not react with a noble gas because a noble gas does not want any electrons. This means, it's outer shell or valence shell is filled with electrons.
What kind of gas is argon?
Argon is a Noble gas--one with eight electrons in its outer shell.
How many electrons does it take to fill the outer shell to become like a noble gas?
For most elements, a complete outer shell, like that of a noble gas, has eight electrons. There are exceptions. Helium, which is the most noble of the noble gases, has only two electrons in its outer shell. A few other light elements only need two (and hydrogen can also exist with no electrons at all, in the form of a naked proton, which is also a form of completion for the outer shell).
How many electrons are found on the outer shell of the noble gas group?
2 or 8
How can elements acquire a stable atomic structure like that found in a noble gas?
Atoms will gain, lose, or share electrons to match the number of outer shell electrons of a noble gas.
What is the valence of Xenon?
Xenon has a valence of 0, as it is a noble gas and has a full outer shell of electrons.
How many electrons does a chemically stable atom have in its outer energy level?
8 electrons
