Helium... that's what i found in chemicalelements.com ... but on my science homework (Crossword) it doesnt fit because of the L in Chlorine. :/
Helium is a noble gas with 2 electrons.
(Respond to earlier message:)
I have the same science homework, and if it still helps, 18 down is Fluorine, not Chlorine. And 20 across is Helium.
What else can I help you with?
How do atoms achieve noble gas electron configurations in single covalent bonds?
They achieve noble gas configuration by the sharing of electrons.
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.
Which atom has two more electrons than an atom of a noble gas?
The Alkaline Earth metal which comes just after the noble gas
How many electrons will a calcium atom Ca lose in order to get a noble gas configuration?
Calcium will lose two electrons to gain the noble gas configuration of Argon.
Which element will have a noble gas configuration if it forms an ionic bond by accepting two electrons from a magnesium atom?
The element that will have a noble gas configuration by accepting two electrons from a magnesium atom is oxygen. By gaining two electrons, oxygen will achieve a stable octet configuration similar to that of a noble gas, fulfilling the octet rule.

What element is a noble gas and has 36 electrons?
Krypton is a noble gas with 36 electrons.
How many electrons does barium has to give up to achieve a noble gas electron configuration?
Barium has 2 valence electrons. It needs to give up these 2 electrons to achieve a noble gas electron configuration, specifically by having a filled outer shell like a noble gas.
How many electrons does barium have to give up in order to achieve a noble gas electron configuration?
Barium has 2 electrons in its outer shell. In order to achieve a noble gas electron configuration it needs to lose these 2 electrons. This will leave it with the same electron configuration as Xenon, a noble gas.
What is the noble gas configuration of strontium?
The noble gas configuration of strontium is [Kr]5s². Strontium has an atomic number of 38, which means it has 38 electrons. The noble gas before strontium is krypton ([Kr]), which has 36 electrons. The remaining two electrons fill the 5s orbital in strontium, leading to the noble gas configuration [Kr]5s².
