Reactivity is defined as the tendency of an element to undergo a chemical reaction. Look at the reactivity trend below for both metals and nonmetals. Use the trends in reactivity above to decide if statement below is TRUE or FALSE.
1.
The reactivity of metals increase as you move left to right across a period.
2.
The reactivity of nonmetals increase as you move left to right across a period.
3.
The reactivity of metals increases as you move down a group.
4.
The reactivity of nonmetals increases as you move down a group.
5.
Potassium (K) is a more reactive metal than Calcium (Ca).
6.
Chlorine (Cl) is more reactive than Fluorine (F).
1. FALSE - The reactivity of metals generally decreases as you move left to right across a period.
2. TRUE - The reactivity of nonmetals generally increases as you move left to right across a period.
3. FALSE - The reactivity of metals generally decreases as you move down a group.
4. TRUE - The reactivity of nonmetals generally increases as you move down a group.
5. TRUE - Potassium (K) is a more reactive metal than Calcium (Ca).
6. FALSE - Fluorine (F) is more reactive than Chlorine (Cl).
