oxygen
Argon has the fewest protons among the elements listed, with 18 protons. Chlorine has 17 protons, nitrogen has 7 protons, and krypton has 36 protons.
If you look at the periodic table, the atomic number denotes the number of protons in the element. For example, the first element on the table is hydrogen, and it has one proton (the fewest). Element number two is helium, and it has two protons, etc.
The element which has the smallest atomic number has the smallest number of protons. In this case, argon has a proton number of 18 (therefore it has 18 protons in each atom), but nitrogen has fewer protons - it has a proton number of just 7, meaning that it has seven protons per nitrogen atom.
In chemistry, a synthetic element is a chemical element that does not occur naturally on Earth, and can only be created artificially. So far 20 synthetic elements have been synthesized (those with atomic numbers 99-118). so the answer is the element Ensteinium with atomic number 99.
Helium has the fewest valence electrons, with only 2 valence electrons.
hydrogen, helium, and lithium
Rhenium (Re) is a transition element from period 7 with the fewest protons among its atoms. It has 75 protons in its nucleus.
hydrogen
Argon has the fewest protons among the elements listed, with 18 protons. Chlorine has 17 protons, nitrogen has 7 protons, and krypton has 36 protons.
The element with the fewest protons found in group 2 of the periodic table is beryllium (Be). It has 4 protons in its nucleus. Beryllium is an alkaline earth metal and is located in the second column of the periodic table.
Aluminum has the fewest protons among carbon, aluminum, sodium, and oxygen. Aluminum has 13 protons, while carbon has 6, sodium has 11, and oxygen has 8 protons.

helium with 2 proton Hydrogen has 1 proton.
Among hydrogen, lithium, and sodium, hydrogen has the smallest atomic radius because it has the fewest number of electron shells and the smallest number of electrons, leading to a smaller atomic size.
