What is the name of group 2 or IIA?
Group 2A — The Alkaline Earth Metals. 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.
What is group VA on the periodic table?
Group 5A (or VA) of the periodic table are the pnictogens: the nonmetals nitrogen (N), and phosphorus (P), the metalloids arsenic (As) and antimony (Sb), and the metal bismuth (Bi).
What is the name of group I II VII VIII?
Template:Periodic table (group names)
| IUPAC group | 1 | 8 |
|---|---|---|
| Mendeleev (I–VIII) | I | VIII |
| CAS (US, A-B-A) | IA | VIIIB |
| old IUPAC (Europe, A-B) | IA | VIII |
| Trivial name | H and Alkali metals |
Why is group 2A called alkaline earth metals?
The alkaline earth metals are named after the alkaline earths whose old-fashioned names were beryllia, magnesia, lime, strontia, and baryta, after their oxides. For two reasons, these elements are referred to as Alkaline Earth metals, Their oxides remain in the crust of the earth and are very heat-stable.
What are the Group 17 elements called?
halogen
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 is the name of Group 7A?
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 6A called?
Group 6A (or VIA) of the periodic table are the chalcogens: the nonmetals oxygen (O), sulfur (S), and selenium (Se), the metalloid tellurium (Te), and the metal polonium (Po). The name “chalcogen” means “ore former,” derived from the Greek words chalcos (“ore”) and -gen (“formation”).
How many elements are in group VA?
Although all the elements in this group form compounds in which their oxidation state of +5 equals the group number, their other properties vary considerably. Nitrogen is clearly nonmetallic and consists of diatomic triply-bonded N2 molecules….12.6: Group VA Elements.

How many groups are there?
There are 18 numbered groups in the periodic table; the f-block columns (between groups 2 and 3) are not numbered.
What is the name of group Viia?
the halogens
The elements in group VIIA are called the halogens and the elements in group VIIIA are called the noble gases or the inert gases. The metals in group IB (copper, silver and gold) are sometimes called the coinage metals.
Why is Beryllium not included in alkaline earth metals?
i) They are obtained from the earth in the form of ores. ii) Their oxides and hydroxides show basic (alkaline) natures. Beryllium fulfills the first criterion but not the second one, since its oxides and hydroxides show amphoteric behavior, rather than alkaline. So, it is not considered an alkaline earth metal.
What are Group 8 elements called?
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 kind of elements are in Group IIA?
Group IIA, the alkaline earth metals, contains: beryllium, magnesium, calcium, strontium, barium,and radium. What elements are found in Group 2A?
What are the elements in Group 2 called?
These elements are called the Alkaline Earth Metals. This group consists of Beryllium, Magnesium, Calcium, Strontium, Barium, and Radium. Q: What are group IIA elements called? Write your answer… What are the elements in group iia called? The group 2A elements are the alkali metals. Why IIA group elements are harder than IA group elements?
How are the elements in group IVA classified?
The elements in Group IVA can be divided into three classes: tin and lead, which are metals. Tin and lead are among the oldest metals known. Tin and lead are much less reactive than any of the groups IA, IIA, or IIIA metals.
What are the names of the elements in group VIIA?
The alkali metals react with the nonmetals in Group VIIA (F 2, Cl 2, Br 2, I 2, and At 2) to form ionic compounds or salts. Example: Chlorine reacts with sodium metal to produce sodium chloride, table salt. Because they form salts with so many metals, the elements in Group VIIA are known as the halogens.
