To determine which element would have properties most similar to lithium, we should consider the atomic structure of lithium, which has 3 protons, 4 neutrons, and 3 electrons. The atomic number (which is the number of protons) of lithium is 3, making it the first element in Group 1 (alkali metals) of the periodic table.
The chemical properties of an element are largely determined by its number of protons (or equivalently, its electron configuration). Elements in the same group of the periodic table usually exhibit similar chemical properties due to their similar valence electron configurations.
To find an element with similar properties to lithium, we can look for elements that have the same number of valence electrons (which is primarily determined by the number of protons). In this case, lithium has one valence electron (because it is in Group 1).
Other elements in Group 1 that have similar properties include sodium (Na), which has 11 protons, 12 neutrons, and 11 electrons, and potassium (K), which has 19 protons and 20 neutrons.
Thus, an element with similar properties to lithium would be sodium (Na), as they both belong to Group 1 of the periodic table and have similar chemical behaviors, though sodium has more protons and neutrons than lithium.
