The atoms with the strongest metallic properties can typically be found in the lower left of the periodic table.
To determine which atoms on the periodic table have the strongest metallic properties, you need to consider the position of the elements. Metallic properties tend to increase as you move from the upper right to the lower left on the periodic table.
In the upper right region of the periodic table, you will find nonmetallic elements like oxygen, nitrogen, and fluorine. These elements have high electronegativity and tend to gain or share electrons rather than lose them, making them less metallic.
In the lower left region of the periodic table, you will find metals like alkali metals (Group 1) and alkaline earth metals (Group 2). These elements have a tendency to lose electrons and form positive ions, which is a characteristic of metallic behavior. They have strong metallic properties due to their low ionization energy and low electronegativity.
Therefore, the answer is "the lower left" on the periodic table where you can find atoms with the strongest metallic properties.
