group-17 elements are called halogens. They are non-metals.They have 7 valence electrons.
the group1 elements
The ist group elements Alkali metals are most active elements.
As a general rule, these are the elements toward the top of the group in the periodic table.
halogens
Oxygen is the most active nonmetallic element in group 16, also known as the oxygen group or chalcogens. It readily reacts with many elements to form oxides.
In terms of reactivity, Potassium(K) is the most reactive element among group 1 elements.
The most active elements on the periodic table are located in Group 1, also known as the alkali metals. These elements are highly reactive due to their tendency to lose their outermost electron to achieve a stable electron configuration.
The most active group of nonmetals are those in Group 17, and these are the halogens. The list is headed by fluorine, which is the most reactive element of the group and of the Periodic Table as a whole.
Group 1 on the periodic table consists of alkali metals. These elements are highly reactive and have one electron in their outer shell. The group includes elements like sodium, lithium, and potassium.
Most of them are called the group of INorganiccompounds.
Not counting the Noble Gases in the last group of the Periodic Table, the most active elements are located at the lower left and upper right. Assuming you are talking about pure, elemental gases, that would make Fluorine the most active gas. Not counting the Noble Gases in the last group of the Periodic Table, the most active elements are located at the lower left and upper right. Assuming you are talking about pure, elemental gases, that would make Fluorine the most active gas.
Most active metals are found on the left side of the periodic table, specifically in groups 1 and 2. These metals have a tendency to lose electrons easily, leading to their reactivity with other elements. Examples include alkali metals like lithium, sodium, and potassium.
