How many valance electrons are found in a atom of each what elements Helium?
Helium has two valence electrons
Noble gas with two electrons?
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.
Do all noble gases have eight valence electrons?
Yes, except for helium which only two electrons. All noble gases are found under the noble gas family to the far right of the periodic table.
How many valence electrons are found in the most atoms of the noble gasses?
The Noble Gases are so-called because they do not readily react chemically with anything, due to their valence electron shells being filled with 8 electrons. The exception, of course, is helium, He, which only has 2.
Where are element with few valence electrons found on the periodic table?
toward the left- apex
How many valance electrons are found in a atom of each what elements Helium?

Valence electrons in a sentence?
valence electrons are the electrons found in the outermost energy level of bohr diagram for an element.
How many valence electrons would be found in an atom of hellium?
Helium has 2 valence electrons, and it's the only noble gas that doesn't have 8 valence electrons.

The number of valence electrons found in an atom of Group A element is equal to?
If by group A u mean Group 1, that would be one. Except for the transition metals, the # of valence electrons is equal to the one's place of the group #, except for helium because it can only have 2 and it is in the 8 group, but that is the group that has the most it can have.
What is the number of the prinicpal energy level in which valence electrons are found?
The valence electrons are the outer most electrons and the principal energy level in which they belong will vary for element to element and generally corresponds to the period number in which the element is present
Number of valence electrons found in an atom of a group A element is equal to what?
group #

How many valence electrons are there in phosphuros?
The number of valence electrons in any element can be found from the element's group number on the periodic table. Phosphorus has a group number of 5 (15 in some periodic tables, in which case the valence is the group number minus ten). Thus, phosphorus has 5 valence electrons.

How many electrons can the element helium lend?
In theory 2 but in practice this has never been found. Helium is extremely stable and holds on to its electrons and does not share or "lend" them.
