Question

Which property of an element determines its position in the activity series?

a Atomic mass
b Atomic radius
c Reactivity
d Solübility in water

Answer 1

Reactivity is the property of an element that determines its position in the activity series.

Step-by-step explanation:

The property of an element that determines its position in the activity series is reactivity.

Reactivity refers to the ability of an element to undergo a chemical reaction. Elements with higher reactivity tend to be more easily oxidized or reduced. Reactivity is influenced by factors such as atomic structure and electronegativity.

Answer 2

c. Reactivity

Step-by-step explanation:

The reactivity of an element is the key property that determines its position in the activity series. Elements with higher reactivity tend to be placed higher in the activity series, indicating their ability to readily undergo chemical reactions and displace elements below them in the series.
