The most electrons an outer shell for group IA metals can have is 2 because IA metals are of the s energy level the max they can hold in an orbital is 2 electrons.

What is the valence number for sodium?
sodium belongs to IA group element in periodic table.hence valence is one
What is the relationship between the group and the number of valence electrons in periodic table?
They are the same! Elements in group IA (alkali metals) have 1 valence electrons. Elements in group IIA (alkaline earth metals) have 2 valence electrons. Group IIIA (boron family) has 3 valence electrons, and so on.
How many additional valence electrons does fluorine need to have a full valence?
I believe you are talking about fluorine. If you are, F needs one more electron to gain a full shell.If you go to WikiAnswers for this information, that is counterproductive, because there is a much better way to do it. Look at the periodic table. Groups IA through VIIIA tell you what you need to know. IA has one valence electron, IIA has two valence electrons etc. Fluorine is in group VIIA and therefore has seven valence electrons. All atoms want eight, and thus fluorine is in need of one more.
Which element in the 3 period has 3 valence electrons?
Aluminum, element number 13. You can tell how many valence electrons an element has by looking at its group (column). This rule only applies for the metals and nonmetals, however. In other words, columns IA, IIA, (skip the middle section starting with Sc and ending with Zn) IIIA, IVA, VA, VIA and VIIA have 1, 2, 3, 4, 5, 6 and 7 valence electrons, respectively.
How do IA and IIA differ the other Group A elements?
base in my experience.... because of the gravity of the earth...

What shows the number of valence electrons in an atom pictorial fashion?
It's called the Periodic Table of the Elements, and it's very possibly the most useful thing in all of chemistry. The more you use it, the more comfortable you become with it, and the more it teaches you.
How many Valance electrons in oxygen?
6 Use the periodic table as a guide. As you go across from left to right the number of valence electrons increases. H = 1 Be = 2 B = 3 C = 4 N = 5 O = 6 F = 7 This trend stays the same all the way down each column. Usually periodic tables are marked on the top with roman numerals or something to signify how many valence electrons each element has.
Number of electrons on an s sublevel in the outermost electron shell of the group IA?
one electron

What change occurs in valence shells of elements as you move from left to right in any given row of the periodic table?
From left to right on the periodic table, the elements in each group (column) have one more electron in their outer shell. For example, sodium (located on the far left side of the periodic table) has only one valence electron. Helium (located on the far right side of the periodic table) has 8 valence electrons. If the periodic table you're labels the 'A' and 'B' groups, then seeing the pattern is fairly easy. When you ignore the 'B' groups (transition metals), a very easy rule applies: whatever group (column) an element is in, that's the number of electrons in the outer shell. Elements in Group IA (like sodium) have one valence electron. Elements in Group IIA (like calcium) have 2 valence electrons. Likewise, elements in Group IIIA (like aluminum) have three valence electrons. This rule applies to all elements located in 'A' groups. For example, simply by looking at the periodic table, you can tell that fluorine has seven valence electrons because it is located in Group VIIA. In answer to your question, from left to right, on the periodic table, the number of valence electrons an element has increases.

What is the Electron group arrangement for CH4?
Electron group arrangment and molecular geometry is same.It is tetrahedral in shape
Which elements have one valence electron?
In addition to hydrogen, all elements in Group I of the periodic table have one valence electron. They are lithium, sodium, potassium, rubidium, cesium, and francium. The farther you move right on the periodic table the more valence electrons. For example, elements in Group VII have 8 valence electrons except helium.
What do groups IA and group IIA elements have in common?
They are both very reactive because of their low number of valence electrons, they both react with water (with the exception of beryllium oxide), and they form positive ions. They are all metals.
