What is Group 1 of the periodic tables name?
What is Group 1 of the periodic tables name?
alkali metals
Group 1A (or IA) of the periodic table are the alkali metals: hydrogen (H), lithium (Li), sodium (Na), potassium (K), rubidium (Rb), cesium (Cs), and francium (Fr).
What is the family name for group 1 elements?
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 is a group name on the periodic table?
The vertical columns on the periodic table are called groups or families because of their similar chemical behavior. All the members of a family of elements have the same number of valence electrons and similar chemical properties. The horizontal rows on the periodic table are called periods.
What are the 5 named groups on the periodic table?

- Group 3: the scandium family.
- Group 4: the titanium family.
- Group 5: the vanadium family.
- Group 6: the chromium family.

What is the biggest group on the periodic table?
Group 1
Group 1(H, Li, Na, K, Rb, Cs, Fr) is the longest group in the periodic table. The first group is called the alkali metals group.
What are the groups on the periodic table called?
Periodic Table of Elements The periodic table is the tabular arrangement of all the chemical elements on the basis of their respective atomic numbers. In the periodic table, the vertical columns are called ‘groups’ and the horizontal rows are called ‘periods’.
What are the vertical columns on the periodic table called?
In the periodic table, the vertical columns are called ‘groups’ and the horizontal rows are called ‘periods’. The modern periodic table is based on the modern periodic law put forward by the English physicist Henry Moseley, which states that “the properties of elements are periodic functions of their atomic numbers”.
Who was the creator of the periodic table?
Seeing chemical elements arranged in the modern periodic table is as familiar as seeing a map of the world, but it was not always so obvious. The creator of the periodic table, Dmitri Mendeleev, in 1869 began collecting and sorting known properties of elements, like he was playing a game, while traveling by train.
