How many valence electrons are found in an atom of each what element Helium?
Helium has 2 valence electrons.
How can you determine the number of valence electrons in an atom?
You can determine how many valence electrons an atom has by what family the element of the atom is in. For instance, if the element is in family 8A, the number of valence electrons will be 8. Or, if the element is in family 2A, the number of valence electrons for the atom will be 2. So, whatever number family the atom is in, the number of valence electrons equals that.
Which things determine an element's electronegativity?
the number of valence electrons in the atom's outer shell how much the valence electrons are shielded from the nucleus
How many valence electrons are in calcium?
Calcium is a non metal element. There are 20 electrons in a single atom.
How many valance electrons are in an atom of phosphours?
there are 5 valence electrons in a Phosphorus element!
How many valence electrons are found in an atom of each what element Helium?
Helium has 2 valence electrons.

How many valence electron are needed for an atom to be stable?
It depends on the atom. List what element the atom is from.
How many valance electrons in an atom of the element gallium?
3 valence electrons
Which things determine an element's electronegativity?
the number of valence electrons in the atom's outer shell how much the valence electrons are shielded from the nucleus
How many electrons can an atom hold in its outermost level?
The number of valence electrons depends on the element and it could have 1 to 8 valence electrons.
How many valence electrons are in calcium?
Calcium is a non metal element. There are 20 electrons in a single atom.
What does the number of electrons on the outershell of an atom tell us?
The valence of the element
What is the reactivity of an atom determined by?
It's determine by the vacancy (unfilled orbital) in the outermost shell of an atom.
What re valence electrons?
Valence electrons are: In chemistry, those electrons found in orbits farthest from the nucleus of the atom. These electrons determine the way in which the atom will combine with other atoms, and thus determine its chemical properties.
The chemical properties of an atom depend on the number of what?
It depends on the number of electrons in the outer valence shell in the atom
If an atom of iodine gains one electron it will have the same number of valence electrons as which element?
The same number of valence electrons as xenon.
