The halogen group of elements is the most reactive of the nonmetals. It is also the most reactive group of all chemical elements. Fluorine is the most reactive element in this group.Know More
Halogens are highly reactive because they are all electronegative. They can gain electrons very quickly which is what makes them react so strongly to other elements. Halogens can form many bonds very fast. Fluorine, for example, only has the choice of losing seven electrons or gaining one, so it almost always gains the one electron since this is much easier. As a result, it often rips electrons away from other elements in order to gain this electron and become stable.
The halogens include fluorine, chlorine, bromine, iodine and astatine. The most reactive element from group seven is fluorine which is at the top of that section of the periodic table. The further down the group you go, the less reactive the element is. Halogens are poisonous to humans on the whole, though each one is poisonous to a different degree. The halogens also tend to be poor conductors of electricity and heat. These chemicals exist at all phases of matter including solid, liquid and gas; they are the only elemental group that has this characteristic.Learn more about Chemistry
Fluorine belongs to group number 17, which is the halogen family of elements that also includes astatine, iodine, bromine and chlorine. The element fluorine is a highly reactive gas at room temperature that is not found freely in nature. Fluorine has a melting point of 363.32 degrees F, a boiling point of 306.62 degrees F and a density of 0.001696 grams per cubic centimeter.Full Answer >
Lithium is in the "alkali metals" group in the periodic table of the elements. Elements in the alkali metals group, also known as Group 1A, each have one electron in its outer shell and other distinct, shared properties.Full Answer >
In the periodic table, elements in the same group or family have similar chemical properties because they have the same number of valence electrons in their outer shells. When the group numbers on the periodic table are given in the older system that uses Roman numerals from IA to VIIIA, it simply is a matter of looking at the group number to know the number of an element's valence electrons.Full Answer >
Aluminum belongs to the Boron family, which is group number 13 on the periodic table of elements. The other elements in the Boron family are the metals thallium, indium, gallium and the semi-metal boron. The element aluminum is a solid metal at room temperature that is assigned the period number 3 and atomic number 13 on the periodic table of elements.Full Answer >
