What group does the alkaline earth metals belong to?
Alkaline earth metals belong to Group 2 of the periodic table, which consists of beryllium, magnesium, calcium, strontium, barium, and radium. They are known for their high reactivity and are commonly found in nature as compounds rather than pure elements.
Why are the halogens not found naturally in the earth's crust as the pure elements?
Halogens are highly reactive elements that readily combine with other elements to form compounds. This reactivity prevents halogens from being found in their pure elemental form in nature. Instead, halogens are commonly found in the Earth's crust combined with metals or other elements to form compounds such as salts.
What are the elements fluorine chlorine bromine and iodine called?
These elements are typically called halogens, and they are found in Group 17 of the periodic table.
What is halogens atomic number?
The halogens are located on the left of the noble gases on the periodic table. These five toxic, non-metallic elements make up Group 17 of the periodic table and consist of: fluorine (F), chlorine (Cl), bromine (Br), iodine (I), and astatine (At).
What group of elements has seven valence electrons?
Group 17 elements, also known as the halogens, have seven valence electrons. This group includes elements such as fluorine, chlorine, bromine, iodine, and astatine.
