The chemical reactivity of metals tends to increase from left to right across the periodic table. true or false
2 answers:
Answer:
False.
Explanation:
The metal elements are located further to the center and to the left of the Periodic Table. To know if one metal is more reactive than another, it is important to remember the concept of electropositivity, that is, the ability of one atom to give electrons to another atom during a bond.
Thus, if one metal is more electropositive than another, it is more likely to lose electrons in a bond and therefore tends to be more reactive. As electropositivity follows the pattern of increasing atomic radius, to evaluate the reactivity of metals in the Periodic Table, we will follow the same principle, namely:
- in the family, reactivity increases from top to bottom (vertical yellow arrow);
- in the period, the reactivity increases from right to left (horizontal yellow arrow).
