What is the first element in the halogen group?
The first element in the halogen group is fluorine. It is a highly reactive non-metal with a pale yellow hue.
What is the significance of the first ionization energy of s in determining the reactivity of an element?
The first ionization energy of an element, like sulfur (s), is important in determining its reactivity. A low first ionization energy means it is easier for the element to lose an electron and form a positive ion, making it more reactive. Conversely, a high first ionization energy means it is harder for the element to lose an electron, making it less reactive.
Which element does the first 7s electron appear?
The first 7s electron appears in francium (element 87) on the periodic table.
Is francium a radioactive element?
Francium (Fr) is a natural radioactive element, extremely rare.
What is a very reactive non metals?
The highly reactive non-metals are in the halogen group. They just need one more electron to fill the octet. Therefore they are highly reactive. For example fluorine and chlorine. And the highly reactive metals are placed in the first group (alkali metals). For example Sodium and potassium.

Which column contains the most reactive elements?
The column that contains the most reactive elements is the alkali metals column, which is the first column in the periodic table. Alkali metals are highly reactive due to having only one electron in their outer shell, making them eager to lose this electron and form positive ions.
What are the most reactive nonmetals in the halogenes?
First of all, all halogens are non-metals. Secondly, the most reactive is fluorine, which reacts to nearly everything, hence it is rare. After fluorine comes chlorine, then bromine and iodine.
If you were looking for a very reactive atom would you look in group 1 or 18?
You would look for a very reactive atom in group 1, also known as the alkali metals. These elements have one electron in their outermost shell, making them highly reactive as they easily lose this electron to form positive ions. Group 18, on the other hand, consists of the noble gases which are highly stable and unreactive due to having a full outer shell of electrons.
What are the most active groups in the periodic table?
The most active groups in the periodic table are Group 1 (alkali metals) and Group 17 (halogens). Alkali metals are highly reactive due to their tendency to lose an electron, while halogens are highly reactive due to their tendency to gain an electron to achieve a full outer shell.
Which element does the first 7s electron appear?
The first 7s electron appears in francium (element 87) on the periodic table.
Which gaseous element was first isolated in 1886 by Henri Moissan?
Fluorine was the gaseous element first isolated in 1886 by Henri Moissan through the electrolysis of hydrogen fluoride. It is a highly reactive and toxic gas that is commonly used in various industrial applications.
Is francium a radioactive element?
Francium (Fr) is a natural radioactive element, extremely rare.
Which first ionization energy is the most probable for a very reactive metal?
A low first ionization energy is most probable for a very reactive metal. This means that the metal can easily lose its outermost electron to form a positive ion, which is characteristic of highly reactive metals.
Does magnesium have a greater first ionization energy than strontium?
About twice as large, which is not that much at the first ionization level. Still, Magnesium has a slightly larger, one proton nucleus and one more electron in that valence level to add to the energy needed to pill the first electron out of it's orbital. Electron shielding may have something to do with this also as the other valance electron of this 2+ element may shield the pulled electron.

The highly reactive non-metals are in the halogen group. They just need one more electron to fill the octet. Therefore they are highly reactive. For example fluorine and chlorine. And the highly reactive metals are placed in the first group (alkali metals). For example Sodium and potassium.
