6.The elements in group 2 are classified as

Which statement best describes Group 2 elements as they are considered in form top to bottom of the Periodic Table? The number of principal energy levels a) increase, and the number of valence electrons increases. b) increases, and the number of valence electrons remain the same c) remains the same, and the number of valence electrons increases

7.The elements in group 2 are classified as

Seven valence electrons, so elements from this group typically exhibit a -1 oxidation state; Noble Gases . The noble gasses have complete valence electron shells, so they act differently. Unlike other groups, noble gasses are unreactive and have very low electronegativity or electron affinity.

as the atoms of the group 17 elements in the ground state are considered from top to bottom, each successive element has the same number of valence electrons and similar chemical properties an atom that has an electron configuration of 2-8-13-2 is classified as

10.The elements in group 2 are classified as

Elements are typically classified as either a metal or nonmetal, but the dividing line between the two is fuzzy. Metal elements are usually good conductors of electricity and heat.
