if you were looking at the periodic table of elements, how could you explain which elements are more reactive than others?

The number of electrons in the outermost shell of an atom determines its reactivity. Noble gases have low reactivity because they have full electron shells. Alkali metals are highly reactive because they readily lose the single electron in their outermost shell.

happy to

pls mark as brainliest

acceleration= v2-v1/t so 8m/s-3m/s / 3s =to 8/3 or

2.67 m/s^2
