Why might two elements possess similar chemical properties?

because they are close to each on the or in the same group as each other on the table of elements. also they have the same number of electrons

Explanation:

Elements which have same number of valence electrons generally show similar chemical properties.

Therefore, elements of same group have similar chemical properties.

For example, chlorine and bromine belongs to same group and hence they have similar chemical properties.

Thus, we can conclude that two elements possess similar chemical properties as they will have same number of electrons in their valence shell.

the "dirty dozen" chemicals banned in an international treaty are formally known as persistent organic pollutants, or pops. the united nations environment program provided this background on what they are and what they can do to humans and wildlife.
