How many valence electrons should an element to react with a element with 7 valence electrons?
one valence electron
What is the correct lewis structure for selenium?
The correct Lewis structure for selenium (Se) would have 6 valence electrons represented by the symbol "Se" surrounded by 6 dots or lines (representing valence electrons), giving a total of 12 electrons in the structure.
What is an element dot structure?
Lewis Dot Structures (LDS) are used to show the valence electrons on an element. Such as Iodine would be described as the letter I surrounded by 7 dots in somewhat of a square outline. Some tips on writing your own: * Start out with element's symbol. * Find the number of valence electrons it has, just valence no other. * Start at the top and place one, then go around in a clockwise manner, placing a dot for every valence electron. * DO NOT MAKE PAIRS UNTIL YOU HAVE TO. Elements with 4 or less valence electrons will not have pairs, therefore there should be no pairs on the diagram. * When you get to the fifth valence electron dot, mark it right next to your original one and continue until you have reached the end. * THERE SHOULD BE NO MORE THAN EIGHT DOTS ON A LDS SYMBOL.
What number of valence electrons in fluoride?
To answer this question and all other questions about valence electron, you should know where the element is on the periodic table. You can see that F is the 7th group. F is fluorine, which has 7 valence electrons. Fluoride is F with a negative charge which means it has one more electron, so Fluoride has 8 valence electrons.
How many valence electrons does H2O2have?
H2O2 is a compound, and the concept of "valence electrons" applies to atoms but not to compounds. If the question is or should be intended to be, "How many valence electrons did the atoms in one formula unit of H2O2 have before they reacted to form the compound?", the answer is one from each hydrogen atoms and six from each oxygen atom, for a total of 14.
What is the dot structure for strontium?
. Sr .There should be two valence electrons around the element since Strontium is in the second column of the Periodic Table and has two valence electrons filling the 5s shell.
How many valence electrons should an element to react with a element with 7 valence electrons?
one valence electron
How many valence electrons does BeCl2 have?
Since Be is in the 2nd group, it should have 2 valence electrons and Cl should have 7 (in 7th group), and since there is 2 Cl, then there is 14. Add 14 Cl electrons and 2 Be electrons to get 16 electrons (valence, not total)
How many dots should you draw in the Lewis structure for carbon C?
im almost positive that you would use 10 electrons. carbon has 4 valence electrons but since you have to that makes eight, and then of course the 1 valence for each of the hydrogen atoms, 2, so that gives you ten
What is the correct lewis structure for selenium?
The correct Lewis structure for selenium (Se) would have 6 valence electrons represented by the symbol "Se" surrounded by 6 dots or lines (representing valence electrons), giving a total of 12 electrons in the structure.
What is the process for drawing a CO Lewis dot structure?
To draw a CO Lewis dot structure, first determine the total number of valence electrons for carbon and oxygen. Carbon has 4 valence electrons and oxygen has 6. Next, place the least electronegative atom (carbon) in the center and connect it to the more electronegative atom (oxygen) with a single bond. Fill the remaining valence electrons around the atoms to satisfy the octet rule. Carbon should have 8 electrons and oxygen should have 8 electrons. If there are extra electrons, place them on the central atom.

Number of valence electrons in chlorine?
I think that because chlorine has 17 electrons in all, and ten of them are filled up on the first two shells, then seven of them should be on the third shell, so seven of them are valance electrons.
What is the Lewis dot structure for SrO?
. Sr .There should be two valence electrons around the element since Strontium is in the second column of the periodic table and has two valence electrons filling the 5s shell.
The electron dot structure for Cl?
The electron dot structure for Cl (chlorine) consists of the chemical symbol Cl surrounded by 7 dots representing the 7 valence electrons of a chlorine atom. These dots are placed around the symbol to show the distribution of electrons in the outer energy level.
How many dots should be drawn in the lewis dot structure for an oxygen atom?
In a Lewis dot structure for an oxygen atom, there should be six dots. Lone pairs of electrons are represented by dots around the symbol for the atom. Oxygen has six valence electrons, so it will have a total of six dots in its Lewis dot structure.
