FranReactivity decreases across a period because the outermost electrons are held more tightly by the increasing nuclear charge, making it harder for atoms to lose or gain electrons to form compounds. This results in a decrease in chemical reactivity as you move from left to right across a period.

How does the the reactivity of metals change when moving from left to right on the periodic table?
Generally, the reactivity of metals decreases as you move from left to right across the periodic table. This is because metals on the left side of the periodic table have fewer valence electrons and are more likely to lose them to form positive ions, making them more reactive. As you move to the right, metals have more valence electrons and are less likely to give them up, leading to lower reactivity.
What is the periodic trend for reactivity of metals?
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.
How does reactivity change as you move across the periodic table?
Reactivity generally decreases as you move from left to right across the periodic table within a period. Atoms on the left have fewer valence electrons and are more reactive in forming bonds compared to atoms on the right, which have more valence electrons and are less inclined to form bonds. However, reactivity tends to increase as you move down a group within the periodic table.
As you move across a period elements have the same number of?
As you move across a period, elements have the same number of electron shells but different numbers of valence electrons. This leads to differences in reactivity and chemical properties across the period.
What is the order of reactivity of alkaline earth metals?
The order of reactivity of alkaline earth metals decreases down the group. This means that the reactivity decreases as you go from beryllium to radium. Beryllium is the least reactive, while radium is the most reactive.
