Elements with valency 1 are those elements which can either gain one electron or lose one electron in order to have stable electronic configuration.
An example is chlorine with atomic number 17. It has electronic
configuration as 2,8,7.
Hence, it accepts one electron to form Cl and attains stable octet configuration. Such elements are non-metals.
Whereas, elements like sodium with atomic number 11 have electronic configuration as 2,8,1.
It is easier to lose the outermost electron to become stable and form Na+. Such elements are metals.
Hence, the correct option is C.

Understanding Valency
Valency refers to the combining capacity of an element, determined by the number of electrons an atom can lose, gain, or share to form a compound. Elements with a valency of one are versatile in their ability to bond with others.
Elements with Valency One
- Metals: Some metals, like sodium (Na) and potassium (K), have a valency of one. They tend to lose one electron to achieve a stable electronic configuration, forming positive ions (cations).
- Non-Metals: Non-metals such as chlorine (Cl) and fluorine (F) also exhibit a valency of one. These elements gain an electron to complete their outer shell, forming negative ions (anions).
- Metalloids: Metalloids can have variable valency, but they do not predominantly exhibit a valency of one.
Conclusion
The key takeaway is that elements with a valency of one can be either metals or non-metals. This dual nature highlights the diversity of chemical behavior in the periodic table. Therefore, the correct answer is option 'D,' as it acknowledges that both categories can exhibit a valency of one. Understanding these distinctions is crucial in grasping the fundamental concepts of chemistry.
