d-block elements or transition metals
As you move across the periodic table from left to right, the elements within a given row have their electrons in the same energy level (given by the number of the row they are in). They way they differ is by the number of electrons. Moving from left to right, the number of electrons increase.
All the Group 14 elements has 4 electrons in its outer energy level.

They are called halogens. They are in the 17th period. They have 7 electrons in the outermost energy level.
Elements on the right side of the periodic table require large amounts of energy to remove an electron from the outermost energy level of their atoms. It is much easier for them to gain rather than lose electrons.
The number of electrons to be gained or lost is what differientiates metallic and non-metallic elements on the periodic table at a subatomic level.

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.
The first period of the periodic table's elements all have 1 energy level.
All of the elements in a given horizontal row (or period) have the energy level, but they differ in the number of valence electrons.
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.
Their valence electrons are in the same energy level.

A period is a horizontal row on the periodic table of the elements. There are seven periods on the periodic table. Each period corresponds to the highest energy level that contains electrons. For example, the elements in the first period have electrons in the first energy level, which is the only energy level available; the elements in the second period have their highest energy electrons in the second energy level; the elements in the third period have their highest energy electrons in the third energy level, and so on.
All the Group 14 elements has 4 electrons in its outer energy level.
The elements in groups 14 through 18 on the periodic table.
An atom's "group" is its column position in the Periodic Table of the Elements. Elements in the same group in the periodic table have similar chemical properties. This is because their atoms have the same number of electrons in the highest occupied energy level.
