cfa - atoms, periodic table, and ions. all elements in a column have: similar characteristics and properties; different characteristics and properties; different valence electrons; the same number of valence electrons; both the same number of valence electrons and characteristics and properties

cfa - atoms, periodic table, and ions. all elements in a column have: similar characteristics and properties; different characteristics and properties; different valence electrons; the same number of valence electrons; both the same number of valence electrons and characteristics and properties

Answer

Brief Explanations:

Elements in a column (group) of the periodic table have the same number of valence electrons, which leads to similar chemical characteristics and properties.

Answer:

E. both the same number of valence electrons and characteristics and properties
