lithium and fluorine
The element found in the same period as sulfur and argon, and more reactive than both, is chlorine. Chlorine is a highly reactive nonmetal that belongs to the same period (or row) as sulfur and argon on the periodic table.
The element found in group 13 and in period 2 is Boron (B). It has an atomic number of 5 and is located in the second period and the thirteenth group of the periodic table.
Element number 113 (Nihonium) can be found in group 13 and period 6 of the modern periodic table. It is a synthetic element created in a laboratory and is highly reactive due to its configuration of valence electrons.
what element is found between period 2 and group 14
Potassium (K) is an element. It is available on the periodic table of elements.
The element Silicon (Si) is in the third Period on the Periodic Table. It is also the second element in Group 14(4) - The Carbon Family. It has 14 electrons in 3 shells, with 4 electrons in the outer shell.
The element is krypton (Kr)
Oxygen is the element with the symbol O on the periodic table. It is a highly reactive nonmetal that is essential for life and is found in many compounds, including water.
Carbon is in period 2. To find the period number, you can look at the row in which the element is located on the periodic table. Carbon is in the second row of the periodic table, so it is in period 2.
Sodium, being a reactive element In group 1, cannot be found as element in nature. One of its common compounds is rock salt.
I would easily say that Fluorine is the most reactive element in the world. Fluorine is the most electronegative of all elements and will react with all elements. It is so reactive that it cannot be found alone in nature.
It is a natural element but, because it is highly reactive, pure barium is not found in nature.
