Who makes up the seven group?
The halogens in group 7A (or VIIA) of the periodic table are fluorine (F), chlorine (Cl), bromine (Br), iodine (I), and astatine (At). The Greek words halo- (salt) and -gen (formation), which make up the name halogen, are related. The elements of group 17 are known as halogens, and group 7 actually corresponds to the 17th group of the periodic table. The group’s non-metallic elements—fluorine (F), chlorine (Cl), bromine (Br), iodine (I), and astatine (At)—have seven valence electrons in their valence shells.The transition metals are the elements that belong to groups 3 through 12. Depending on the metal, they can form cations with various charges; the most frequent ones are 2, 3, and 4. These groups’ constituent elements make up the d-block, and the partially filled d-orbitals in these metals enable the formation of colorful compounds.The family of carbon is in group 14. The five components are lead, tin, silicon, germanium, and silicon. In their lowest energy level, each of these elements has four electrons. Only carbon and silicon can form covalent bonds as nonmetals among the Group 14 elements.Second in the periodic table after Group 3 is Group 4 for transition metals. It consists of the four elements titanium (Ti), zirconium (Zr), hafnium (Hf), and rutherfordium (Rf). Following the family’s lightest member, the group is also known as the titanium family.
