The 2nd element on the Periodic Table is helium. It is a colorless, odorless gas that is lighter than air. Helium is non-reactive and has a low boiling point, making it useful in various applications such as filling balloons and cooling superconducting magnets.
The element in the 3rd period and 2nd group of the periodic table is magnesium (Mg).
litium, and elements in the 2nd period (row) are pretty common
Helium is the second lightest element on the periodic table, with an atomic number of 2 and an atomic weight of approximately 4.0026 atomic mass units.
The halogens are a group of elements in the periodic table that includes fluorine, chlorine, bromine, iodine, and astatine. They are highly reactive nonmetals that readily form compounds with other elements.
You can discover this by looking at a periodic table of the elements.The rows of the table are called periods; the columns are called groups.The second period therefore begins with the element Lithium and ends with the element Neon.
The second element is element number two: Helium
The element in the 3rd period and 2nd group of the periodic table is magnesium (Mg).
litium, and elements in the 2nd period (row) are pretty common
This element is calcium. It is the fifth most abundant element in the Earth's crust and makes up more than 3 percent of the crust. It reacts with water and belongs to the 2nd group of the periodic table.
The element on the left side of the periodic table would be metal and on the left side would be non-metal.... 1st group of the periodic table has alkali metals,2nd group has alkaaline earth metals,etc.
Helium is the second lightest element on the periodic table, with an atomic number of 2 and an atomic weight of approximately 4.0026 atomic mass units.
its the 2nd element on the periodic table and it makes things lighter, such as helium balloons, which float as helium is lighter than air
halogenhalogen in group VII
The halogens are a group of elements in the periodic table that includes fluorine, chlorine, bromine, iodine, and astatine. They are highly reactive nonmetals that readily form compounds with other elements.
2nd row (or 2nd period), group 17
Look up "the photographic table of elements" on your favorite search engine but...its in the 2nd row.
