Correct Answer: Lithium<\/strong><\/p>\n\n\n\n Valence electrons are the electrons located in the outermost energy level (or shell) of an atom. These electrons determine how an element reacts chemically and what kind of bonds it forms.<\/p>\n\n\n\n Let\u2019s look at each element and count its valence electrons:<\/p>\n\n\n\n From the above, we can clearly see that lithium<\/strong> has the fewest valence electrons among the given options. It has only one electron in its outermost shell. This is consistent with its placement in Group 1<\/strong> of the periodic table, known as the alkali metals. Elements in this group are highly reactive and tend to lose that single valence electron easily to form a positive ion.<\/p>\n\n\n\n This single valence electron also explains why lithium, like other alkali metals, is very reactive in chemical reactions, especially with water, and tends to form ionic compounds. Its low number of valence electrons is also the reason it is a good conductor of electricity and has a low melting point relative to other metals.<\/p>\n\n\n\n In conclusion, lithium<\/strong> has the fewest valence electrons among the four listed elements.<\/p>\n\n\n\n which of the following elements has the fewest valence electrons? beryllium. boron. carbon. lithium. The Correct Answer and Explanation is: Correct Answer: Lithium Explanation: Valence electrons are the electrons located in the outermost energy level (or shell) of an atom. These electrons determine how an element reacts chemically and what kind of bonds it forms.
