Elements in groups 1A through 7A are often referred to as representative elements because they display a wide range of physical and chemical properties.
What is an example of a group 1A element?
alkali metal, any of the six chemical elements that make up Group 1 (Ia) of the periodic table—namely, lithium (Li), sodium (Na), potassium (K), rubidium (Rb), cesium (Cs), and francium (Fr).
What are the names of groups 1A/2A 7A and 8A?
Some groups have special names:
- Group 1A: Alkali metals.
- Group 2A: Alkali earth metals.
- Groups 3B-2B: Transition metals.
- Group 7A: Halogens.
- Group 8A: Noble gases.

What is group 7A on the periodic table?
Fluorine is a halogen, which is a group of non-metals located on the right side of the periodic table that includes fluorine (F), chlorine (Cl), bromine (Br), iodine (I), and astatine (At). Most halogens are electron-hungry, like fluorine. Halogens can also be referred to as group 7A, group 17, or group VIIA elements.
Is Group 7A cation or anion?
The unknowns will be in the form of an aqueous solution and will contain a Group 2A cation and a Group 7A anion.
Why are 1A group elements called as alkali metals?
The elements of group 1 are called alkali metals because their oxides and hydroxides form alkaline solutions on treating with water. Therefore, the solution becomes basic or alkaline due to the formation of hyroxide ions.
What are 1A 3B and 7A examples of on the periodic table?
The periodic table have the groups and periods. In the periodic table, there are 7 horizontal rows of elements are known as period and 18 vertical columns of elements are known as group. Hence, 1A, 3B, and 7A are examples of group number on the periodic table.
What is 1A in periodic table?
alkali metals Group 1A (or IA) of the periodic table are the alkali metals: hydrogen (H), lithium (Li), sodium (Na), potassium (K), rubidium (Rb), cesium (Cs), and francium (Fr). These are (except for hydrogen) soft, shiny, low-melting, highly reactive metals, which tarnish when exposed to air.
Where is group 7A on the periodic table?
Fluorine is a halogen, which is a group of non-metals located on the right side of the periodic table that includes fluorine (F), chlorine (Cl), bromine (Br), iodine (I), and astatine (At). Most halogens are electron-hungry, like fluorine. Halogens can also be referred to as group 7A, group 17, or group VIIA elements.
What is halogen family?
halogen, any of the six nonmetallic elements that constitute Group 17 (Group VIIa) of the periodic table. The halogen elements are fluorine (F), chlorine (Cl), bromine (Br), iodine (I), astatine (At), and tennessine (Ts).
What are group 7 elements called?
the halogens Group 7A (or VIIA) of the periodic table are the halogens: fluorine (F), chlorine (Cl), bromine (Br), iodine (I), and astatine (At). The name "halogen" means "salt former", derived from the Greek words halo- ("salt") and -gen ("formation").
What is group 7 called?
The elements in group 7 are called halogens. In the periodic table, they are put in the vertical column, second from the right. The three common Group 7 elements are chlorine, bromine and iodine.
Why are elements of group 7a called halogen?
Halogen means 'salt-forming compounds'. Group 7 elements when they react with metal forms salt, hence the name halogen.
What group of elements are halogens?

Are group 1 elements metals or nonmetals?
Group 1A (or IA) of the periodic table are the alkali metals: hydrogen (H), lithium (Li), sodium (Na), potassium (K), rubidium (Rb), cesium (Cs), and francium (Fr). These are (except for hydrogen) soft, shiny, low-melting, highly reactive metals, which tarnish when exposed to air.
Which group of elements in the periodic table is known as the halogens *?

Which list is only metalloids?
Metalloids are the smallest class of elements, containing just six members: boron (B), silicon (Si), germanium (Ge), arsenic (As), antimony (Sb), and tellurium (Te).
Why are elements of group 7A called halogen?
Halogen means 'salt-forming compounds'. Group 7 elements when they react with metal forms salt, hence the name halogen.
