Since the first element ever produced synthetically was Technetium, then it will be in the Transition Metal block.
The 85th element in the periodic table is astatine (At). Astatine is a rare and radioactive element that belongs to the halogen group, similar to fluorine and chlorine. It is primarily produced synthetically in laboratories due to its short half-life.
The element that contains 14 protons in its atoms has the atomic number 14. On the Periodic Table, this element is silicon, Si.
group 18
It is about nitrogen. N atom contains 7 protons.
well there is metals meatlloids nonmetals gases solids liquids synthetically prepared element so i guess 7????

No. There are twenty elements that can only be produced synthetically.
Lawrencium is an artificial element.
Iodine-131 is not natural, matter of fact it is a synthetically produced isotope (im doing this for my science assignment aswell)
Technetium is the only element that has not been found in nature but has been produced synthetically.
The element with atomic number 85 in the Periodic Table is Astatine (At). Astatine is the second radioactive element, but is not synthesised. It is part of the Group 17 - Halogens family. It has 85 electrons in 6 shells with 7 electrons in the outer shell.
The element that contains 14 protons in its atoms has the atomic number 14. On the Periodic Table, this element is silicon, Si.

The element with the lowest atomic number among the transuranium elements is neptunium, with an atomic number of 93. It is the first transuranium element produced synthetically in a laboratory setting.
It is about nitrogen. N atom contains 7 protons.
The hundredth element on the periodic table is fermium, with the symbol Fm and atomic number 100. It is a synthetic element that is radioactive and typically produced in nuclear reactors.
