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?
Strontium Sr would have the least attraction for an electron.
As the atomic number increases, so does the electro negativity of the elements in group II A; the lower an atom's attraction to an electron is, the lower its position in the periodic table.

The atoms of strontium (Sr) will have the least attraction for an electron among the elements beryllium (Be), magnesium (Mg), calcium (Ca), and strontium (Sr) within their group. This is because as you move down a group in the periodic table, the electronegativity generally decreases. Sr, being lower down the group compared to Be, Mg, and Ca, will have the least electronegativity and thus the least attraction for an electron.

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
