A complete outer electron shell is (for most elements) 8 electrons, not 7, so I don't know why you are asking about "all seven electrons" as if 7 is a complete set. The halogens have seven valence electrons; the noble gases have 8.
^ kinda rude it would be the column begining with F (fluorine)

Which column on the periodic table has the same number of valence electrons?
For example the column 17 - halogens.
What is a group in the periodic table called?
the vertical column is called group in the periodic table.
Why are Fluorine Chlorine Bromine and Iodine in the same column of the periodic table?
they have the same number of electrons
What is a colunm in the periodic table?
In the Periodic Table of the Elements, a column (group) contains all elements that exist with the group number of electrons in the outer energy level of an atom of that element.
In what column is beryllium in?
Beryllium is in column 2 of a wide form periodic table and column II(A) of a narrow form periodic table.
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 best describes why krypton is located in the last column on the periodic table?
Krypton is a noble gas. It has 8 electrons in the outermost shell. So it is in the last column of the periodic table.
How many electrons are in the outer ring of cesium?
Cesium has one valence electrons in its outer ring, as indicated by its placement in column 1 of a wide form periodic table or column IA of a narrow form periodic table.
A verticle column in the periodic table?
In the Periodic Table of the Elements, a column (group) contains all elements that exist with the group number of electrons in the outer energy level of an atom of that element.
What does the periodic table have seven of?
valence electrons and energy sublevels
What is a family on the periodic table?
A family is a column in a periodic table; all elements in a family have similar physical and chemical properties, because they have the same numbers of valence electrons (outer electrons).
What does elements in a column of the periodic table have?
Elements in same column have same number of outermost electrons. It determines chemical properties.
What is a group in the periodic table called?
the vertical column is called group in the periodic table.
How do you know how many valence electrons does calcium have?
its in column two on the periodic table, so therefor it has two valence electrons .
How are the number of neutron and electrons calculated?
By which column and geoup number it is in on the periodic table i learnt it in science
How do you tell what elements in the periodic table have the same number of electrons in their outer orbitals?
They are in the same column.
