Re: Valence electrons
Additionally, does this mean the dots around an element in a structure are just electrons?

Re: Valence electrons
Valence electrons are the electrons in the outer shell of an atom and contribute to the formation of bonds between atoms. In Lewis structures, the dots do represent the valence electrons.

Re: Valence electrons
How do we determine how many valence electrons there are for elements in the middle of the periodic table?(The part that doesn't abide by the normal rules)

Re: Valence electrons
I believe that transition metals typically have 2 valance electrons because they are part of the d-orbitals which are being filled after the next s-orbital. By this I mean for example the 4th period would be in the 3d state while also being in the 4s and because 4s is the outter most shell, that would mean there are 2 electrons in the outter shell.

Re: Valence electrons
Valence electrons are the unpaired electrons in the highest energy orbital in a given atom. Indeed, the dots in Lewis structures represent valence electrons. You will usually see them in a pair, as electrons like to be paired. If not, the atom is called a radical, as the single lone electron makes the atom unstable.

Re: Valence electrons
Yes dots represent valence electrons but you should always count the amount of valence electrons for an atom. Oxygen for example has 6 valence electrons and they can be represented through lines (bonds) and lone pairs in which the sum of the lines (1 line=2 valence electrons) and the lone pairs would equal 6 in the case of oxygen

Re: Valence electrons
The dots around atoms in Lewis structures for molecules represent the valence electrons that do not participate in bonding. Valence electrons are just the electrons in the outermost orbital of an atom.

Re: Valence electrons
Yes, the dots around the atom represent valence electrons. 2 together is a lone pair, 1 is a radical, and a line represents a bond. Hope this helps!

Re: Valence electrons
The dots in lewis structures are valence electrons. These types of electrons are on the outermost shell and can be used to determine types of chemical bonding.

Re: Valence electrons
In Lewis structures, valences electrons are represented by dots surrounding the atom.

Re: Valence electrons
Yes, when drawing Lewis structures, the dots around an atom represents its valence electrons relative to the bond.
Re: Valence electrons
The dots represent the electrons that are not being shared, so they are usually in a lone pair, unless you are working with a radical structure.

Re: Valence electrons
Yes the dots seen in lewis dot structures are the valence electrons and these are the electrons that form bonds with other atoms or compounds.
Re: Valence electrons
Yes; the dots seen in Lewis structure are valence electrons. These electrons are the most susceptible to form bonds or be gained/lost in order to create a full valence shell and result in a more stable atom.

The dots around the atoms in a Lewis Structure are the unpaired electrons that are not being shared, so yes they are the atom's valence electrons.

Re: Valence electrons
Valence electrons are the electrons in the most outermost shell (highest n). The dots signify each valence electron that is not bonded.
