Because it meets the criteria of the group and row as told and predicted by Mendeleev. The simplest reason it is in group 7 is because it has 7 electrons in it's outer shell!
The name given to group 7 elements in the Periodic Table are halogens.
There are 7 valence electrons in a fluorine atom. Fluorine is in group 17 of the periodic table, so it has 7 electrons in its outermost energy level.
halogens- its group (family) 7 on the periodic table
The name given to group 7 elements in the Periodic table are halogens.
Fluorine, F, is in group 17 (7A) and period 2.
The name given to group 7 elements in the Periodic Table are halogens.
F stands for fluorine. It is placed in group-15.
There are 7 valence electrons in a fluorine atom. Fluorine is in group 17 of the periodic table, so it has 7 electrons in its outermost energy level.
halogens- its group (family) 7 on the periodic table
The periods are the rows, and the groups are the columns, so Fluorine, F, is in Period 2 (and Group 7).
The name given to group 7 elements in the Periodic table are halogens.
Group 7 of the periodic table is known as the halogens group. The gases in this group are fluorine (F2), chlorine (Cl2), bromine (Br2), iodine (I2), and astatine (At2). Of these, fluorine and chlorine are diatomic gases at room temperature, while bromine is a liquid and iodine is a solid.
Iodine appears in group 7 of the periodic table (halogens) because it has 7 valence electrons. This property makes it chemically similar to other elements in the group, such as fluorine, chlorine, and bromine. Grouping elements with similar chemical properties helps in organizing the periodic table.
Fluorine, F, is in group 17 (7A) and period 2.
Group 17 elements have the highest electronegativity out of which fluorine has the highest electronegativity.
No, phosphorus is not a halogen. Phosphorus is a nonmetallic element in group 15 of the periodic table, while halogens are a group of elements in group 17 of the periodic table that include fluorine, chlorine, bromine, iodine, and astatine.
Group 7 on the periodic table is called the halogens. This group includes elements like fluorine, chlorine, bromine, iodine, and astatine. Halogens are highly reactive nonmetals that readily form salts with metals.
