What is 7a in the periodic table?
"A" is not used as a symbol in the periodic table. Each element is represented by a unique symbol, such as "H" for hydrogen or "Na" for sodium. If you meant "7A" as a group number, group 7A includes the halogens (fluorine, chlorine, bromine, iodine, and astatine).
Are bromine and chlorine in group 7a of the periodic table?
Bromine and chlorine are in group VII A, which could also be designated Group 7a, of the narrow form periodic table that was commonly used before 1980. Most chemists now prefer a wide form periodic table, in which these elements are in column 17.
Where is the bromine on the periodic table?
Bromine is in Group 7: The Halogens, below Fluorine and Chlorine but above Iodine and Astatine.
Is group 7A cations?
Group 7A cations refer to the cations of Group 7A elements in the periodic table, also known as the halogens. Some common examples of Group 7A cations include fluoride (F-), chloride (Cl-), bromide (Br-), and iodide (I-).
Why halogens are placed in group 7A in the periodic table?
Halogens are placed in Group 7A of the periodic table because they have seven electrons in their outermost energy level, making them highly reactive and likely to gain one electron to complete a full valence shell. This characteristic is consistent with other elements in the same group, which also tend to gain an electron to achieve stability.

What family does fluorine belong to in the period table?
Halogen
How does bromine relate to the periodic table?
Bromine is an element on the periodic table. It has an atomic number of 35. It can be found near the right side of the table. Bromine is located in the Halogens group, which is group 7A or 17, and is also in period 4.
How is group 7 related to the halogen family?
Group 7A is the Halogen group. It is sometimes also called Group 17, depending on how the periodic table is labeled.
Groups in 7a on the periodic table are known as?
Halogens
Is group 6A the halogens family?
Yes, group 6A in the periodic table is not the halogens family, but rather the group consists of chalcogens such as oxygen and sulfur. The halogens family is group 7A, which includes elements like fluorine and chlorine.
Where is the bromine on the periodic table?
Bromine is in Group 7: The Halogens, below Fluorine and Chlorine but above Iodine and Astatine.
Are Group 7A elements the alkaline earth metals?
No, Group 7A elements are the halogens - a highly reactive group of nonmetals. Alkaline earth metals are found in Group 2A of the periodic table and are characterized by being shiny, silvery-white metals that react readily with water.
Is group 7A cations?
Group 7A cations refer to the cations of Group 7A elements in the periodic table, also known as the halogens. Some common examples of Group 7A cations include fluoride (F-), chloride (Cl-), bromide (Br-), and iodide (I-).
Is group 7a on the periodic table metal non metal or metalloids?
1. After the obsolete USA system group 7A contain nonmetals. 2. After the modern IUPAC rules group 7 contain metals (A and B doesn't exist now).
When Group 7A elements in a periodic table form ions do they lose or gain protons?
The elements in group 7A or 17, gain one electron during ionic bonding, or share one electron when undergoing covalent bonding.
