The answer is cadmium.
Option (c) is the correct answer.
Metallic character means the level of reactivity of metals. It is known that metals have excess of electrons, therefore, in order to follow octet rule they readily lose electrons to attain stability.
Sodium and potassium are metals and therefore, they have high metallic character.
Whereas silicon is a non-metal and readily reacts with a metal to completely fill its valence shell.
On the other hand, krypton is a noble gas and has completely filled shell. Therefore, it's reactivity will be the least.
Thus, we can conclude that krypton has the least metallic character.
krypton is the answer blah blah blah is this enough letters
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.
