The farther the valence electron are from the nucleus, the more easily they can be lost therefore the more reactive the element is.
i.e potassium would be more reactive than sodium (check their valence electrons)

What has the author Philip Cadman written?
Philip Cadman has written: 'Studies in chemical reactivities'
Why did Mendeleev arrange elements in periods?
He arranged the elements in the increasing order of atomic mass and repeating properties so that it is easy to study the properties / reactivities of the elements.
Why are the elements listed in the same column of the periodic table?
because they have the same number of valence electrons and hence have similar properties and reactivities.
How many elements do you currently know of?
Today the periodic table contain 118 chemical elements; 94 are considered natural elements.
What are the three important elements of chemical elements?
Metals nonmetals and metalliods
When looking at a periodic table of elements what do you know by knowing in which column an element appears?
Chemical elements in the same group have similar chemical properties.
How do you know it is a chemical?
All substances which are not pure elements are chemicals.
What chemical elements make up detergent?
i dont know but i want to know about it..please..;(
What is the arragenment of all the known elements in order of their atomic numbers?
The list is often called the periodic table, given that it can be arranged in ways which bring out the patterns in their reactivities.
Do calcium and barium have the same reactivities?
No, they do not.
Are there 120 atoms there in all?
Probably you think at chemical elements; we know today 117 elements (112 elements were homologated now by IUPAC).
What elements on the periodic table do you need to know?
An informed and curious person need some knowledge about all chemical elements.
