Some people disagree on whether hydrogen is in group 1, but the elements in group 1 are Li (lithium), Na (sodium), K (potassium), Rb (Rubidium), Cs (caesium), and Fr (francium). These are the ones that react violently with water, with Li giving the weakest and Fr the strongest reaction. Hope that helps :)

The name of group 1 in the periodic table?
The elements in group one are the alkali metals.
What is group 4 on the periodic table of elements?

Which can be found on a periodic table elements compounds or mixtures?
Elements are found on periodic table. Compounds are not present on periodic table. The table does not contains mixture.Elements can be found on a periodic table. Compounds can be made by bonding two or more elements. But they are not depicted on the periodic table.
How does the modern periodic table arrange the elements?
In the modern version of the periodic table, the elements are arranged in increasing order of the atomic number. The chemical properties of an element can be predicted by its group. For example group 1 elements react violently to give away one electron to form +1 ions where group 18 elements are inert in standard temperature and pressure. This periodic table was introduced by Henry Mosley.
What families are in Group one periodic table?
Group one of the periodic table is known as the alkali metal group and includes the elements lithium (Li), sodium (Na), potassium (K), rubidium (Rb), cesium (Cs), and francium (Fr).
One of the elements of group 17 of the periodic table?

a family is a column of elements a period is a row of elements
What is group in periodic table?
In the periodic table, group indicates the number of valence electrons in the outermost shell. E.g. Group I- the elements in that group have one valence electron in the outermost shell.
