The most reactive elements on the periodic table are the alkali metals and the halogens, and are located in the very left row and second row from the right respectively
On the periodic table the elements are called groups.
The Periodic Table of the Elements, sometimes called just the Periodic Table, is the document in which elements are organized by their properties. It was created in 1869.
It is named The PERIODIC TABLE. The periods being the horizontal rows The groups being the vertical columns.
Rows in the Periodic Table are called Periods.There are 7 periods in total.All the elements in period have same number of energy levels.
Artificial elements.
It is called the Periodic Table of Elements.
On the periodic table the elements are called groups.
The Periodic Table of the Elements, sometimes called just the Periodic Table, is the document in which elements are organized by their properties. It was created in 1869.
The elements located in the first column, group IA on the periodic table, are called alkali metals.
The representative elements are usually called the main group elements or the Group A elements. They are located in the leftmost and middle sections of the periodic table, excluding the transition metals.
It is named The PERIODIC TABLE. The periods being the horizontal rows The groups being the vertical columns.
transition elements
The elements located in the middle of the periodic table are called transition metals. They are known for their metallic properties, ability to form colored compounds, and variable oxidation states. Transition metals are often used in industrial applications due to their unique characteristics.
The pattern of repeating properties of elements in the periodic table is called periodicity. This periodicity arises from the similar electronic structure and arrangements of elements within the table.
Rows in the Periodic Table are called Periods.There are 7 periods in total.All the elements in period have same number of energy levels.

Because the elements progress in a periodic function.
