How can the number of valence electrons be determined from the periodic table?
By looking at the group number you can tell how many valance electrons there are ex: Group 1= 1 valance electrons Group 2-12= 2 valance electrons Group 13= 3 valance electrons Group 14= 4 valance electrons Group 15= 5 valance electrons Group 16= 6 valance electrons Group 17= 7 valance electrons Group 18= 8 valance electrons ...

What are the valencies of some common elements?
Carbon = 4 valance electrons. Oxygen = 6 valance electrons. Chlorine = 7 valance electrons. Sodium = 1 valance electron Magnesium = 2 valance electrons. Neon = 8 valance electrons. I am reading this at the top of my periodic table where every group of elements has it's valance number listed. ...

How many Valance electrons in oxygen?
Oxygen has 6 valance electrons. You can figure out the number of valance electrons for any main group element (Group IA-IIA and IIIA-VIIIA) using the periodic table. Group IA- all elements have 1 valance electron Group IIA- all elements have 2 valance electrons Group IIIA- all elements have 3 valance electrons ... Group VIA - 6 valance electrons ... Group VIIIA- 8 valance electrons The number of valance electrons is equal to the group number (which is shown in roman numerals) ...

What is the Lewis structure for TeF6?
F(6 valance electrons)\ /F(6 valance electrons) F(6 valance electrons)-Te-F(6 valance electrons) F(6 valance electrons)/ \F(6 valance electrons) 68 electrons with 20 left over. Te is a group 6 F is a group 7 with 6 times so that is 6+6(7)=68 ...

When chemical bonds form valence electrons are either or between atoms?
Chemical bonds don't form electrons; an element has valance electrons. Covalent bonds are formed when elements share their valance electrons. An element wants to have 8 valance electrons. That is when it is an "happy atom". For example, carbon has has four valance electons, so it typically bonds with hydrogen and oxygen to get those four valance electrons. ...

How can an atom that has 5 valance electrons achieved a full valance of electrons?
it was to gain 3 more valence electrons so it can be like the noble gases. ...

What is unique about valance electrons in transition metals?
The unique about transition metals is that all of them share two valance electrons in their outermost shell. ...
How is the reactivity of elements related to valence electrons in atom?
Valance electrons means that the element has not reached the octet configuration and is therefore reactive the reactivity depends on the no. of valance electrons the more valance electrons the more unstable the atom is and the more reactive it is.The gasses like helium neon xenon are all inert which means they have an octet configuration and have no delocalised or valance electrons. ...
Asked in Chemistry, Periodic Table
Why are most elements on the left of the periodic table metals?
The way the periodic table is arranged, you start on the left with elements having one valance electron, and go across the table adding electrons (with some added complexity as you pass through the transition state elements) until you reach the elements that have eight valance electrons, in the column on the far right, then you go back to the left with one valance electron (eight valance electrons is a full shell, so you then have to start a new shell).
