That's not a very valid question becase you could argue that all the elements in that particular group are important. There are at least 4 common ones there, which are carbon, silicon, lead, and tin.
Iodine is classified as a halogen in the periodic table of elements. It is a non-metal and is part of Group 17 (Group VIIA) of the periodic table.
The elements to the left side of the periodic table in groups VIa and VIIa have high electron affinity, as they tend to gain electrons to achieve a stable octet configuration. Group VIIa elements (halogens) have the highest electron affinities in the periodic table.
Elements with high electronegativities are typically found in Group 17, the halogens, and in Group 16, the chalcogens, of the periodic table. These elements have a tendency to attract electrons towards themselves in a chemical bond.
The halogens are under group 17 (column 17) on the periodic table. They are in the column right next to the noble gases. They have the highest electronegativity values and typically exist as either anions or diatomic gases. Examples of these elements are fluorine, chlorine, bromine, and iodine.
Group 17 is called the halogen-group (F, Cl, Br, I, At, Uus)
Iodine is classified as a halogen in the periodic table of elements. It is a non-metal and is part of Group 17 (Group VIIA) of the periodic table.
No. group VIIA (or group 17) elements are halogens. group VIIIA (or group 18) elements are noble gases.
The elements to the left side of the periodic table in groups VIa and VIIa have high electron affinity, as they tend to gain electrons to achieve a stable octet configuration. Group VIIa elements (halogens) have the highest electron affinities in the periodic table.
The halogens can be found in Group 17 (Group VIIA) on the periodic table. They include elements such as fluorine, chlorine, bromine, iodine, and astatine. These elements have similar chemical properties due to their outer electron configuration.
Chlorine is a member of the halogen group on the periodic table. It is located in Group 17 or Group VIIA.
Chlorine is in Group 17 of the Periodic Table.
Elements with high electronegativities are typically found in Group 17, the halogens, and in Group 16, the chalcogens, of the periodic table. These elements have a tendency to attract electrons towards themselves in a chemical bond.
The halogens are under group 17 (column 17) on the periodic table. They are in the column right next to the noble gases. They have the highest electronegativity values and typically exist as either anions or diatomic gases. Examples of these elements are fluorine, chlorine, bromine, and iodine.
Elements with the highest chloride numbers are typically located in Group 17 (VIIA) of the periodic table, known as the halogens. This group includes elements like fluorine, chlorine, bromine, and iodine, which form highly stable chloride compounds due to their tendency to gain one electron to achieve a full outer shell.
Group 17 is called the halogen-group (F, Cl, Br, I, At, Uus)
Bromine belongs to the halogen family and is in group 17 (group VIIA) of the periodic table.
Mendeleev put bromine and chlorine in the same group on the periodic table because they have similar chemical properties. Both elements belong to group 17 (Group VIIA) due to their similar valence electron configuration and tendency to form halide compounds.
