Elements in the same group in the periodic table have similar chemical properties. This is because their atoms have the same number of electrons in the highest occupied energy level. Group 1 elements are reactive metals called the alkali metals.
People also ask, which elements are main group elements?
In chemistry and atomic physics, the main group is the group of elements whose lightest members are represented by helium, lithium, beryllium, boron, carbon, nitrogen, oxygen, and fluorine as arranged in the periodic table of the elements.
Which group has the most elements?
- In group 1 of the periodic table, all the elements except hydrogen (H) are alkali metals.
- The alkaline Earth metals make up group 2 of the periodic table.
- All the elements in groups 3–12 are transition metals.
- These groups each contain one or more metalloids.
- Group 17 consists of the nonmetals called halogens.
What are the majority of the elements?
Using the periodic table, you can classify the elements in many ways. One useful way is by metals, nonmetals, and metalloids. (See also The Periodic Table: Families and Periods.) Most of the elements on the periodic table are classified as metals.
