Fluorine, chlorine (the symbol is capital C, lowercase L), bromine and iodine are all halogens with similar chemical properties. Elements with similar chemical properties appear in the same columns, called groups, in the Periodic Table. All of the previous elements are in group 17.
Br and Cl possess same properties. So he grouped them together.
They are all in the same column (Group 7) of the periodic table and are also known as the halogens.
a family is a column of elements a period is a row of elements
Elements that have similar chemical properties occupy the same group on the Periodic Table.
Chlorine and Bromine have similar properties. You can tell because they are in the same vertical column in the periodic table.
Elements in the same column have the same number of valence electrons, and form ions with the same charge.
they have the same number of electrons
They are all in the same column (Group 7) of the periodic table and are also known as the halogens.
a family is a column of elements a period is a row of elements
A column is known as a group in periodic table. There are 18 groups in the modern setting of periodic table. Elements in the same group usually share same chemical properties and striking physical characteristic trends.
Elements in the same column have similar chemical properties. They are from the same family.
Elements that have similar chemical properties occupy the same group on the Periodic Table.
For example the column 17 - halogens.
They have the same Valency
All elements within a column are called a group.
Yes
Elements in same column have same number of outermost electrons. It determines chemical properties.
No. It is not the same. the number of valence electrons are same for the elements in the same column (group).
