Chemical, if it gives off a reaction like that its chemical
Answer:
B)As you go from left to right, reactivity of metals increases. As you go down in a group, reactivity of metals decreases.
Explanation:
reactivity of metals can be explained as how it can easily lose electron, i.e oxidize as well as reaction with non-metals.
There are factors that influence the reactivity of metals such as
1)atomic radius
2)nuclear charge
3)shielding effect
4) The sublevel arrangement of electrons
In the periodic table,the group 1, known as alkali metals, are the most reactive metals
Therefore, as we from left to right, reactivity of metals increases. As we move down in a group, reactivity of metals decreases.
