because the ones on the right side are negative..
Elements on the left side of the periodic table are typically metals, such as alkali metals and alkaline earth metals. These elements are known for their high reactivity and tendency to form positive ions. They are good conductors of electricity and heat.
Elements on the left side of the Periodic Table are "Alkali Metals". There is also one non-metal element. H(hydrogen)
The elements that lose electrons and form positive ions are called metals. They will lose the electrons from their highest levels of energy to gain a more positive charge and form positive ions.
Metals on the Left Hand Side of the periodic table
Metals are typically found on the left-hand side of the periodic table. This includes elements such as lithium, sodium, and iron. Nonmetals are generally found on the right-hand side.
In the periodic table metals are on the left of the line. But elements touching it are called semi metals and have properties of both metals and nonmetals
Metals are located on the left side of the Periodic Table.
left side
Metals are positive ions. Everything on the left side of the periodic table is. Basically every element that has 4 valence electrons or less is a positive ion.
Strong electron donors are typically found on the left side of the periodic table, specifically in groups 1 and 2 (alkali metals and alkaline earth metals). These elements have low ionization energies and readily donate electrons to form positive ions.
The metalloids split the table these are a diagonal group of elements, B, Si, Ge, As, Sb and Te. To their right are the non metals to the left the metals. There are many more metals than any other type of element. See Wikipedia article "Periodic table (metals and non metals)"
Left side of periodic table is made up of metals. Group-1,2 elements are metals.
