Which element is less electronegative than silicon (Si)?The Periodic TableA.Magnesium (Mg)B.Carbon (C)C.Oxygen (O)D.Sulfur (S)

The electronegativity of an element refers to its ability to attract electrons in a chemical bond. In the periodic table, electronegativity generally increases as you move from left to right across a period and decreases as you move down a group.

Given the options:

A. Magnesium (Mg) B. Carbon (C) C. Oxygen (O) D. Sulfur (S)

We can eliminate options B, C, and D right away. Carbon and Oxygen are to the right of Silicon in the periodic table, meaning they are more electronegative. Sulfur is below Oxygen, so it is also more electronegative than Silicon.

That leaves us with option A, Magnesium (Mg). Magnesium is to the left of Silicon in the periodic table, meaning it is less electronegative. So, the element that is less electronegative than Silicon (Si) is Magnesium (Mg).
