What are the 8 groups of the periodic table?
These are non-metals which are poor conductors with low melting and boiling points. The Halogen group is also the only group where at room temperature all three states of matter can be seen in the elements. Noble Gases are made of Helium, Neon, Argon, Krypton, Xenon, Radon, and the synthetic gas Oganesson.
What are the groups in a periodic table?
group, in chemistry, a column in the periodic table of the chemical elements. In a group, the chemical elements have atoms with identical valence electron counts and identical valence vacancy counts. Groups are numbered from 1 to 18.
What are the 5 main groups of the periodic table?
5 Element Families
- Alkali metals.
- Alkaline earth metals.
- Transition metals.
- Halogens.
- Noble gases.
What are the 10 groups of the periodic table?
Terms in this set (10)
- Alkali metals. Alkali metals Group 1: very reactive metals which do not occur freely in nature.
- Alkaline Earth Metals. Group 2: next reactive metals, found in earths crust but not in elemental form.
- Transition Elements.
- Lanthanides and Actinides.
- Boron Group.

- Oxygen Group.
What are the 18 groups of the periodic table?
Groups are numbered 1–18 from left to right. The elements in group 1 are known as the alkali metals; those in group 2 are the alkaline earth metals; those in 15 are the pnictogens; those in 16 are the chalcogens; those in 17 are the halogens; and those in 18 are the noble gases.
What are the 3 main groups on the periodic table?
The three broad categories of elements are metals, nonmetals, and metalloids.
Are there 8 or 18 groups in the periodic table?
There are 18 numbered groups in the periodic table; the f-block columns (between groups 2 and 3) are not numbered. An exception is the “iron group”, which usually refers to “group 8”, but in chemistry may also mean iron, cobalt, and nickel, or some other set of elements with similar chemical properties.
What are the 9 groups of the periodic table?
- Groups are also known as Families. The families are the names representing each group.
- There are 9 different families, and these are the:
- Alkali Metals.
- Alkaline Earth Metals.
- Transition Metals.
- Boron.
- Carbon.
- Nitrogen.
What are the 4 main groups on the periodic table?
Elements can be classified as metals, metalloids, and nonmetals, or as a main-group elements, transition metals, and inner transition metals. Groups are numbered 1–18 from left to right.
What is Group 17 on the periodic table called?
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 the 2 main groups in the periodic table?
In chemistry and physics, the main group elements are any of the chemical elements belonging to the s and p blocks of the periodic table. The s-block elements are group 1 (alkali metals) and group 2 (alkaline earth metals).
