Which column on the periodic table has the same number of valence electrons?
For example the column 17 - halogens.
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 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.
What does the column in the periodic table stand for?
they represent elements. the elements in a given column (or group) have the same number of valence electrons and hence similar properties.
Are the numbers of neutrons the same for elements in the same column on the periodic table?
No. It is not the same. the number of valence electrons are same for the elements in the same column (group).
When moving down a group in the periodic table what does the number of valence electrons do?
When moving down a column in the periodic table, except for the first period of column 18, the number of valence electrons remains unchanged.
Which column on the periodic table has the same number of valence electrons?
For example the column 17 - halogens.
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.
On the periodic table elements with the same number of valence electrons are in same?
Elements with the same number of valence electrons are in the same group (or vertical column).
How do elements in the same column on the periodic table have similar properties?
Because they have the same number of valence electrons.
Do all elements in the same column in periodic table have different number of valence electrons?
Yes, it is correct.
The Roman numeral at the top of a column on the periodic table indicates the number of in the outer shell.?
valence electrons
What do elements in a column have in common in the periodic table?
Elements in a given column have the same number of valence electrons and hence the similar properties.
Describe the number of valence electrons in each atom as you move down group 2 in the periodic table?
Every atom in Column 2 of a wide form periodic table has two valence electrons.
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

What do the elements in the periodic table have?
Elements in the same column have the same number of valence electrons, and form ions with the same charge.
