There are 18 groups in the modern Periodic Table.
Elements in group 1 are also known as alkali metals.
Elements in group 2 are also known as alkali earth metals.
Elements in group 17 are also known as halogens (salt makers).
Elements in group 18 are also known as noble gases.
There are 18 groups and 7 periods in the modern periodic table.
The rows of elements in the periodic table are called periods. There are a total of 7 periods in the periodic table, each representing a different energy level or shell in which the elements' electrons are arranged.
Groups in the periodic table are vertical columns that contain elements with similar chemical properties. Elements in the same group have the same number of valence electrons, which determines their reactivity and chemical behavior. There are 18 groups in the periodic table.
7 periods and 18 groups are there on the modern periodic table.
Colunms are named 'Groups'. Rows are named 'Periods'.
Periodic table can be classified as:MetalsTransition elementsNon-metalsThey occupy different groups.
groups are the vertical columns on the periodic table
the vertical columns in the periodic table are known as groups.
A periodic table has seven periods. It also has 18 groups and 4 different families.
7 periods and 18 groups are there on the modern periodic table.
periodic table is classified into groups and periods.There are 18 groups and 7 periods in periodic table.
- the periodic table is organized in periods and groups- chemical elements are listed in the order of the atomic number- the periodic table obey the law of periodicity
Groups represent vertical columns. They indicate different column with different properties.
