What can you say about chemical reactivity of elements in a period from left to right

Period - reactivity decreases as you go from left to right across a period. 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. Period - reactivity increases as you go from the left to the right across a period.

Answer:

Period - When you move from left to right over a period, the reactivity decreases. The higher the goreactivity, the further to the left and down the periodic table you go. Time - When you move from left to right over a period, the reactivity increases. The chemical reactivity of elements decreases and then increases as they move from left to right in a periodic table cycle. If we progress to aluminium (Al) and silicon (Si), the chemical reactivity steadily decreases (Si).
