Select two statements that describe how elements in the same group are similar to each other.
1 answer:
Answer:
A: Elements in the same group share the same number of valence electrons.
D: Elements in the same group share the same reactive properties.
Explanation:
A periodic group is simply the arrangement of elements vertically on the periodic table.
There are about 8 main groups of elements on the periodic table.
Elements in the same group have the same number of valence electrons. This is usually observed in their group numbers. Due to this, they all share the same chemical properties which makes them react the same way. Usually, the number of atoms shell increases down the group. Across a period, elements share the same number of orbitals in their structure. No two elements on the periodic table shares the same number of total electrons.
