How many valence electrons do the nob gas element contain?
noble gases all contain 8 valence electrons because they are in column 8A on the periodic chart
What is the relationship between two elements located in the same column on the periodic table?
They have the same number of valence electrons (electrons in their outermost shell). They do not have the same number of shells however.
How can you determine the number of valence electron atom has?
Look what column it is in within the Periodic Table. The first column has 1 valance electron. The second column has 2 valence electrons. The entire section of shorter columns (all metals) also have two valence electrons. The tall column after that (with Boron ) has three valence electrons. The tall column after that (with carbon) has four valence electrons. This pattern continues until you reach the final column, the noble gasses (eg. Neon, argon, xenon); these all have 8 valence electrons.
What major change occurs as you move left to right on the periodic table?
As you move left to right on the periodic table, the number of valence electrons an element has increases. The number of valence electrons an element has corresponds to which group (column) an element is. (This rule does not apply to transition metals...)
Is an element with seven valence electrons?
All of the Halogens (the second column from the right on the periodic table) have 7 valence electrons. This includes -Flourine -Chlorine -Bromine -Iodine
How many electrons does Ba has?
Valence electrons are electrons that are on the outside "shell." In Group (column) 1, there is only one valence electrons for each element. In Group (column) 2, there are two valence electrons. Group 13: 3 valence electrons Group 14: 4 valence electrons Group 15: 5 valence electrons Group 16: 6 valence electrons Group 17: 7 valence electrons Group 18: 8 valence electrons There is no Group 19, so this list is done. For the metals, each element will need to be mapped out utilizing the Bohr Diagram design or something of the like as valence electrons are difficult to define due to the grouping on the periodic table. The most valence electrons that can be in an outer shell is eight. Barium (Ba) is in Group (column) 2, and thus has only two valence electrons.

What are the properties of a verical column of the periodic table?
The element in a given vertical column (or groups) have the same number of valence electrons and hence have similar properties.
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.
What is the number of valence electrons in the outer shell of each element of group 3?
3: For periodic columns 1 through 3, the number of valence electrons is the same as the number of the periodic column.

How many valence electrons are in TiO2?
The electronic configuration of Tin is [Kr]4d10 5s2p2. Valence electrons are the electrons on the outermost shell of the neutral atom. Since the outermost shell is the 5th one, we have 4 valence electrons (2 of s and 2 of p)
What has 2 valence electrons?
Any element in the 2A column of the periodic chart: Be, Mg, Ca, Sr, Ba, and Ra.
What information does the column number provide on the periodic table?
For main group elements the column number is a concrete indication of then number of valence electrons (and therefore oxidation number). And since it tells you the number of valence electrons you can get a substantially reliable idea of how reactive the element is
