Question

1. Which out of the following elements has the lowest electronegativity: Lithium, Beryllium, Magnesium, Sodium

Answer 1

1. The element Sodium (Na) has a low electronegativity of the following elements.
2. The element Beryllium (Be) has the least metallic character.
3. 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.
