What group is group 8 in?
noble gases
Group 8A (or VIIIA) of the periodic table are the noble gases or inert gases: helium (He), neon (Ne), argon (Ar), krypton (Kr), xenon (Xe), and radon (Rn).
What is group 1A in periodic table?
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.
Is group 8 an element?
Group 8 is a group of chemical elements in the periodic table. It consists of iron, ruthenium, osmium and hassium. They are all transition metals. Like other groups, the members of this family show patterns in electron configuration, especially in the outermost shells, resulting in trends in chemical behavior.
What is Group 9 called in the periodic table?
Transition Metals
Group 9: Transition Metals.
Are there 9 periods in the periodic table?
Periods. There are currently seven complete periods in the periodic table, comprising the 118 known elements. Any new elements will be placed into an eighth period; see extended periodic table.
What is the 9th element on the periodic table?
Fluorine
Fluorine – Element information, properties and uses | Periodic Table.
Where is group 1A on the periodic table?
The alkali metals are six chemical elements in Group 1, the leftmost column in the periodic table. They are lithium (Li), sodium (Na), potassium (K), rubidium (Rb), cesium (Cs), and francium (Fr).
What are group 1A and 7A elements Examples of?
Alkali metals: Group 1A of the periodic table. Alkaline earth metals: Group 2A of the periodic table. Halogens: Group 7A of the periodic table.
What element atomic number is 8?

What are the 8 families of the periodic table?
Families of the Periodic Table. On the periodic table, there are families which are groups of elements with similar properties. These families are alkali metals, alkaline earth metals, transition metals, post-transition metals, metalloids, halogens, noble metals, and noble gases.
What are the names of the 8 groups in the periodic table?
The following are the 8 groups of the periodic table:
- Alkali metals.
- Alkaline earth metals.
- Rare earth metals.
- Crystallogens.
- Pnictogens.
- Chalcogens.
- Halogens.
- Noble gases.

What is 9 on the periodic table?
What symbol has the atomic number 9?
symbol F
Fluorine is a chemical element with symbol F and atomic number 9.
What element is in group 1A period 2?
Group 2A (or IIA) of the periodic table are the alkaline earth metals: beryllium (Be), magnesium (Mg), calcium (Ca), strontium (Sr), barium (Ba), and radium (Ra). They are harder and less reactive than the alkali metals of Group 1A….Group 2A — The Alkaline Earth Metals.
| 2 | |
| 1A | Li |
| 2A | Be |
| 4A | C |
Why are group 1A called 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 elements in group 1A to 8a called?
Some of these groups have special names. The elements in group IA are called the alkali metals. The elements in group IIA are called the alkaline earth metals. The elements in group VIIA are called the halogens and the elements in group VIIIA are called the noble gases or the inert gases.
What is group 1A and 2A in periodic table?
Like the Group 1A elements, the alkaline earth metals are too reactive to be found in nature in their elemental form. The alkaline earth metals have two valence electrons in their highest-energy orbitals (ns2). They are smaller than the alkali metals of the same period, and therefore have higher ionization energies.
