Metals become less reactive across a period due to an increase in ionization energy and a decrease in atomic radius. These factors make it more difficult for metals to lose electrons and form cations, resulting in decreased reactivity.
The most reactive metals are the alkali metals in group 1a.
Two active metals in period 5 of the periodic table are potassium (K) and rubidium (Rb). Both of these metals are highly reactive due to their tendency to lose electrons easily.
Period 6 has the most metals out of all periods on the periodic table.
AnswerAlkali metals are the most reactive metalsFrancium is the most reactive metal. This is as it has many layers, the last layer having only one electron, far away from the positive pull of the proton.
The most reactive metal on the table is Caesium. Fluorine is the most reactive non-metal on the table. For metal periods, reactivity decreases from left to right. Non-metals are the opposite.
These metals lose easily an electron.
The most reactive metals are the alkali metals in group 1a.
no, the alkali metals make up the first period and all of them are highly reactive.
this is called periodicity, the chemical properties of elements as you go across a period. The reactivity would be very great at first, especially if you are only crossing main group elements, and then would become less reactive, then very reactive again, and then one group over they would be completely inert
The alkali and alkaline earth metals are the least electro negative elements, and the halogens are the most electro negative elements.
The metals on the left side of the periodic table are considered to be highly reactive to air while in room temperature. The ones on the right side are less reactive and are often used for construction.
Metals Period - reactivity decreases as you go from left to right across a period.Group - reactivity increases as you go down a group Why? The farther to the left and down the periodic chart you go, the easier it is for electrons to be given or taken away, resulting in higher reactivity.Non-metals Period - reactivity increases as you go from the left to the right across a period.Group - reactivity decreases as you go down the group. Why? The farther right and up you go on the periodic table, the higher the electronegativity, resulting in a more vigorous exchange of electron.
Two active metals in period 5 of the periodic table are potassium (K) and rubidium (Rb). Both of these metals are highly reactive due to their tendency to lose electrons easily.
The trend of boiling points across a period in the periodic table should decrease from metals to nonmetals. The trend becomes more complicated between metals, the boiling point of metals tends to increase across a period.
Period 6 has the most metals out of all periods on the periodic table.

Across the period (left to right), the elements tend to change from solids (metals) to gases (non metals).
