How many valence electrons are there in Ag?
Q. How many valence electrons are there in Ag? And basically, how do you determine valence electrons in general?
Asked by pockochocko - Tue Dec 19 22:57:27 2006 - - 4 Answers - 0 Comments
A. Short answer: Depends how you define "valence". Long answer: A couple of people have said "look at the group number". That's not so helpful. Most people use a standard 1-18 across the table for Group numbers, which means carbon is in Group 14, and it doesn't have 14 valence electrons. If you use an older style notation with Roman numerals, then Fe Co and Ni are *all* in Group VIII, and they obviously can't have the same number of valence electrons, because they're in different columns. So that's no good. Another poster said -- write out the electronic configuration, and the valence electrons are those of the highest principal quantum number. C is (1s)2(2s)2(2p)2, so that's four e- in the n=2 shell, so four valence electrons. Na is ( [cont.]

What 3 elements in the same group have different valence configurations?

How many valence electrons does a Cl atom have?
Q. The electron configuration for chlorine, Cl is [Ne]3s23p5. How many valence electrons does a Cl atom have? Write the symbol for the ion it forms to achieve a noble-gas configuration.
Asked by Cooper - Fri Jan 15 18:33:38 2010 - - 4 Answers - 0 Comments
A. Seven, it needs to gain one more to achieve noble gas configuration. So if Chlorine gains another electron it will become negative so the symbol would be Cl with a little negative one (-1) or sometimes when the charge is negative one you can just write the negative sign (-) on the upper right side of it (like a power). Hope this helps.

Asked by bloopers012345 - Fri Dec 5 01:01:47 2008 - - 1 Answers - 0 Comments
A. Valence electrons are the number of electrons in the outer most energy level. The electron configuration for Cr is [Ar] 3d5 4s1 since 4 is the outer most level, you see it has 1 electron. If you look at F, it has an electron configuration of 1s2 2s2 2p5. It's outer most level is 2 so if you add all the electrons in 2 , it = 7 valence electrons. The reason Cr is not 3d4 4s2 is that the half filled d sublevel is at a lower energy state so the e moves out of the 4s in order to give it the lower energy configuration.

A. There's a trick that you can use for some of the elements of the periodic table. If you look at the left side column, the elements in that column have a valence of +1, and if you move right to the next column, it's +2... Similarly, if you start on the left most column, you have noble gasses with valence of 0, if you move left from there in columns it's -1, -2... Silver is a transition metal, and the trick doesn't work for it, but it's a +1 charge.

A. The valence configuration of the transition metals is unusual because they all technically have 2 valence electrons but they will promote out of the d orbital up into the next energy orbitals. Even with in the same element there can be differences in valence electron number The oxidation number of the the transition metals can be used to find the number of valence electrons. For example copper can be either +1 or +2, this means that it loses either 1 or 2 electrons. So copper either has 1 or 2 valence electrons.

A. Elements with 1/2 filled valence shells give or take electrons to make a complete outer shell these many form covalent (shared electrons) bonds because it requires too much energy to completely strip or add 4 electrons. Elements with less than 1/2 filled valence shells release electrons as it becomes much more difficult to strip electrons to fill their valence shell. Elements with more than 1/2 filled valence shells strip electrons from other atoms. So as one moves to the left on the periodic chart, there are fewer electrons to release and the elements do so. It becomes more energetic to strip the 2nd and 3 electron. As one moves to the right, fewer electrons need to be stripped from others and so the do so more easily. With lower… [cont.]

Asked by ROFLMAOLOL - Mon Sep 28 17:13:56 2009 - - 1 Answers - 0 Comments
A. The valence electrons and outer electrons are the same thing. They are the ones in the highest energy level; in the case of nickel, the two 4s electrons. Oddly enough, the 3d electrons have a higher energy level than the 4s orbital, and so they may enter into chemical reactions along with the 4s electrons, but the 4s electrons are those that are lost first when nickel combines chemically. Notice that the most common valence shown by nickel (and other transition metals) is +2. That comes from the two 4s electrons being lost first. Hope this helps.

why is the number of electrons in the valence of an atom important?
Q. is it because it tells how many charges the element lends or borrwos? is my answer right? 1. how is the number of valence electrons in the atom of an element related to the position of the element in the periodic table? - i know the answer to this, but i don't know how to put it in aproper sentence(s). the number of raws shows how many shells there are, and the family/group show the number of valence electrons. 2. how do you think the reaction of bromine with sodium would compare with the reaction of chlorine with sodium? -the problem is that i don't understand and I just want someone to explain what it is asking. 3.what is the total charge on each of the following ions? one fluorine anion one sulfur anion two nitrogen onions -A [cont.]

A. it determines its ion.
