How do you find the valance of an element in the periodic table?
the group number represents the valency of the elements.
What is the charge on the ion that selenium form ionic compound?
selenium has a -2 charge. when it forms a compound with another atom the charge of the compound should be zero unless it has a cahrge in its equation. when compounds form they try to be in the most stable state which is when all their valance elctrons are full which means the charge is zero.
Why does sulfur have a valency of 4 and 6 when it needs only 2 electrons for stable configuration?
It has 6 electrons in it's valance shell and needs 2 more electrons in it's valance shell to become stable. Some atoms, phosphorous for instance ( valance # 5 ), can reach deeper into their valance shell and make additional covalent bonds.
What is the number of valance electrons as you move right across a row or period in the periodic teale?
It depends on which group you are talking about. The number of valance electron normally increase by one as you move right across the table. when you get to the transition metals however, the valance electron will vary.
How can you find the mass of any compound?
The molar mass of a compound is the sum of atomic weights of elements in the molecule.
How can you find the valance electrons for an atom?
is a compound
What are the two elements that make up the ionic compound LiBr?

Where do you find elements in group 1?
You find them in the left hand column they have 1 protons in the valance shell
How do you find oxidation number in an atom?
By looking to see how mwny valance electrons you have.
Atoms react to achieve four electons in outer shell?
Well according to the octet rule the a compound must have 8 valance electrons to be stable.
What is the valence of sugar?
You have a misconception about the meaning of the word valance. Elements have a valance, not compounds. Sugar has no valance.
How do you find the valance of an element in the periodic table?
the group number represents the valency of the elements.
Was there a real liberty valance?
No, he was a character in the movie The Man Who Shot Liberty Valance. Valance was played by Lee Marvin.
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
How many valance electrons does samarium have?
