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.
<u>Explanation:</u>
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.
