Question

how does the organization of the periodic table help us identify possible substitutions between elements? ready? enter your answer here

Explanation:

Elements in the same group (vertical column) of the Periodic Table have similar chemical properties. This is because they have the same number of valence electrons. So, if we need to find a substitute for an element, we can look at the other elements in the same group as it is likely to have similar reactivity and bonding behavior.

Answer:

Elements in the same group of the Periodic Table have similar chemical properties (due to same valence - electron count), so we can look at elements in the same group for possible substitutions.
