Sodium has lower electronegativity value and a largest atom as compared to given element whereas beryllium has least metallic character.

The element Sodium (Na) has a low electronegativity as compared to other given elements. The electronegativity values of sodium is 0.93, beryllium has 1.57, magnesium has 1.31 and lithium has 0.98 so we can say that sodium has lower electronegativity value.

The element Beryllium (Be) has the least metallic character because beryllium is present at the top of the periodic table. When we go from top to bottom metallic character increases and decreases from left to right in the periodic table.

The element Sodium (Na) has the largest atom among these elements because of more number of shells added when we go from top to bottom which make higher the radius of sodium as well as size so we can conclude that sodium has lower electronegativity value and a largest atom as compared to given element whereas beryllium has least metallic character.

The element Sodium (Na) has a low electronegativity of the following elements.The element Beryllium (Be) has the least metallic character.The element Sodium (Na) has the largest atom.

Explanation:

Sodium (Na) which is a delicate, shimmering white, profoundly responsive soluble base metal loses an electron to a chlorine iota since it has seven electrons in its valence shell. It needs one more electron to turn into a steady molecule. It has the most reduced electronegativity of the given components. Beryllium (Be) is a light, silver-gray, relatively soft metal that is strong but brittle has the least metallic character of the given elements.Since from left to right in a period, Metallic character decreases while nonmetallic character increases from top to bottom.Sodium(Na) is the largest atom among the given elements since Atomic size decreases across a period from left to right and increases from top to bottom.
