electronegativities of the elements be, mg, ca, and sr follow a specific trend within their group. based on this trend, the atoms of which element will have the least attraction for an electron?\nbe\nmg\nca\nsr
Answer
Brief Explanations:
Electronegativity is the ability of an atom to attract electrons. In a group of the periodic - table, electronegativity decreases down the group. Be, Mg, Ca, and Sr are in the same group (Group 2). Sr is the bottom - most element among them, so it has the lowest electronegativity and the least attraction for an electron.
Answer:
Sr
