u know how Li has one valence electron and then on the other side were neon and stuff is and how it has a full outer orbital because as u read 4rm left to right the group/family will always have the same valence electron
The upper right part (example O, F, Cl) and the lower left part (example Cs, Fr, Ra) elements are morte reactive than other parts, but this is only a rule of thumb.
elements on either end of the Periodic Table (except for group 18 elements) are generally more reactive than the elements in the middle of the table.
Reactivity is associated with position. Chemical properties of element can be determined from its position.
Grouping describes the behavior of elements. Different groups have different properties.

Based on the periodicity of the elements regarding properties, reactivity, valence electrons, etc.
Yes

The last column of the periodic table of elements
Periodic Table - Or Table of Reactivty
Atomic number most effects the placement of an element in the periodic table.The properties of the element. (Study Island) :p
because it does not react with other elements
Based on the periodicity of the elements regarding properties, reactivity, valence electrons, etc.
False,reactivity of elements generally decreases from left to right.As free electrons become less,reactivity decreases.So the given statement is false.
a Periodic Table organises the different elements, according to the atoms' mass, type, properties, reactivity etc. See the question about: periodic table patterns
