Question

Non-metals have _________ tendency to gain electrons.
A. More
B. Less
C. No
D. None of the above

Answer 1

We distinguish that metals are materials that are decent conductors of heat and electricity. They possess metallic bonds. The non-metals are generally electronegative in nature and they have the affinity to gain an electron. Likewise, we have to also observe in the case of what valency it must-have for an addition of an electron.

Complete step by step solution:
We can see that metals are electropositive in nature whereas non-metals are electronegative in nature. Metals have dissimilar properties. Metals have very high melting points and density. They have a metallic luster. They are generally solid at room temperature apart from mercury, which is in the liquid state at room temperature. Non-metals are said to be electronegative in nature as they have an affinity for accepting electrons or they can add electrons more effortlessly. Alternatively, metals tend to lose electrons. Metals lose electrons intending to stabilize themselves. They lose electrons since valence electrons of the farthest shell are very inadequately attracted to the nucleus. Non-metals usually have four to eight electrons in their valence shell which aids them to finish their octet by attaining electrons from other elements.
Thus from the above description, it is clear that option (A) is correct,

Note:
Metals are always electropositive in nature and nonmetals are electronegative in nature. Recall that a non-metal is a substance which can gain electrons very easily. They do so usually to complete their octet configuration and It will be hard for them to attain electrons more than two or three. Metals are electropositive in nature as they can lose their valence electrons from their outermost shell.
