It tends to increase. As you go down a group, the outer electron gets further away from the nucleus and is thus not held as tightly which makes it more available and thus reactive.
The elements in a column on the periodic table form a group (or family) because they have similar physical and chemical properties.
Each vertical column on the periodic table are called groups, they are also known as families because they have similar chemical properties to each other.
Elements that have similar chemical properties occupy the same group on the Periodic Table.
Chemical elements in the same group have similar chemical properties.
Silicon, carbon's only neighbor within its periodic table column 14.
Each column is a group of chemical elements.
Chemical properties.
the noble gases are positioned on the last column on the right. As the elements descend down the column they are more reactive
The elements in a column on the periodic table form a group (or family) because they have similar physical and chemical properties.
Elements in the same column on the periodic table have similar chemical reactivity because they have the same outer electron configuration and it is the electron structure that determines an elements properties.
Chemicals in a column, or "group" have similar chemical properties.
Elements in the same column have similar chemical properties. They are from the same family.
Similar chemical properties.
All of the alkali metals, periodic column 1 excluding hydrogen in a wide form periodic table, and all but the two lightest alkaline earth elements, periodic table column 2 excluding beryllium and magnesium, have the reactivity specified by the question.
Elements in same column have same number of outermost electrons. It determines chemical properties.
A group is a column of elements that have the same physical or chemical characteristics.
They have similar (more or less) chemical properties.
