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?\no be\no mg\no ca\no sr
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 (Beryllium), Mg (Magnesium), Ca (Calcium), and Sr (Strontium) are in 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
