what happens to the reactivity of metals from left to right across the periodic table?

Question

Nirajan · Accepted Answer

The reactivity decreases as the number of valence electron increases. So metals with low number of valence electron can easily lose their electron as compared to metals with large number of valence electron.

They become less reactive. Na is more reactive than Mg which is more reactive than Al which is more reactive than Si.

Jeff · Answer

1) B. Metals on the right have more protons, causing valence electrons to be held more strongly. 2) B. by gaining electrons 3) B. They are very nonreactive 4) A. Cs and Br 5) A. Rb loses an electron
