What else can I help you with?
How many electron shells and how many valence electrons are in an atom of an element found in period 3 and group 16 of the periodic table?
This element is sulfur; the electron configuration of sulfur is [Ne]3s23p4. Sulfur has three electron shells cotaining 2, 8 and 6 electrons. The last six are valence electrons.
What element has 2 valence electrons and 4 energey levels?
Calcium has 2 valence electrons and 4 electron shells. It is represented by the chemical symbol Ca.
What element has 2 electron shells and 4 valence electrons?
Well, darling, the element you're looking for is carbon. It struts around with 2 electron shells and 4 sassy valence electrons, making it the life of the chemical party. So, if you're ever in need of a carbon copy, just remember this little fun fact.
What element has 4 valence electrons and 3 shells?
Silicon. Electronic configuration [Ne]3s23p2
What is the relationship between an element's number of valence electrons and its reactivity?
When we say valence electron we mean the number of electron left it the outermost shell of element, valence electron can be positive of negetive. If an element need much electrons to be octet, that means that the element is not reactive than the one who will give out electrons, the the one who can give electrons much are less reactive than the one who can give a litle and the reaction will be normal as it is soppused to be, Eg lithium and berylium. Lithium is more reactive than berylium because lithuin has 1valence electron while berylium has 2....reactivity goes with the action of valence electron in an element
What element has Five shells and 17 valance electrons?
Element 17's valence electron configuration is 3s23p5.
How many electron shells and how many valence electrons are in an atom of an element found in period 3 and group 16 of the periodic table?
This element is sulfur; the electron configuration of sulfur is [Ne]3s23p4. Sulfur has three electron shells cotaining 2, 8 and 6 electrons. The last six are valence electrons.
If an element has 3 electron energy levels rings and 3 valence electrons what element is it?
The element is likely lithium (Li). Lithium has 3 electron energy levels (shells) and 3 valence electrons in its outermost energy level.
What element has 2 valence electrons and 4 energey levels?
Calcium has 2 valence electrons and 4 electron shells. It is represented by the chemical symbol Ca.
How many valence shells does the element neon have?
Period number = no. of electron shells. Therefore neon has two shells.

Electrons of the 19th element?
The 19th element is potassium, which has the atomic symbol K. It has 19 electrons, including one valence electron that can be easily lost.
Are electron shells and valence electrons the same thing?
Valency is the number of electrons in the outer shell the charge is how many electrons is needed to form an octet (full valence = 8 electrons) Eg. Sulfur valence = 6 charge = -2 (needs to gain 2 electrons to gain an octet)
How many valence electron does Sr have?
This is a chemical element. You can find the how many electron in a single atom by using a periodic table.

What determines the properties of an element?
The three factors determine the chemical properties of an element:The number and arrangement of electrons in an atomThe number of valence electronsThe number and arrangement of electrons
