What are the different features of 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
How many periods and groups are there in the periodic table?
Modern periodic table has 7 periods and 18 groups.
How are the elements arranged?
Elements are arranged on the periodic table based on their atomic number, which is the number of protons in their nucleus. This arrangement groups elements with similar properties in columns called groups or families, while elements in the same period have the same number of electron shells.
What are the relationships between the group number on the periodic table?
The periodic table of Mendeleev has 18 groups.
How have microscopes help make the periodic table?
The periodic Table of elements groups the different elements through their electron configuration and number of Protons (atomic number) and also states atomic mass by adding the number of protons and number of electrons.And all of these are checked by microscopes.
What are the groups on the periodic table and how do they relate to the periodic period of elements?
The groups on 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. The periodic period of elements refers to the horizontal rows on the periodic table, which indicate the number of electron shells an element has. Elements in the same period have the same number of electron shells, but elements in the same group can be in different periods.
How groups are there in the modern periodic table?
The group number tells you the number of valence electrons in the outer shell. This is important because it is the valence electrons that participate in bonding, and thus in determining the properties of the element.
What are groups in the periodic table?
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.
What are the rows of periodic table?
Horizontal rows are called groups. Groups are formed according to the atomic number.
How elements arranged in the periodic table?
Elements are arranged on the Periodic Table in the order of the atomic number, in groups and periods.
Which direction are families on the periodic table?
groups on the periodic table are the vertical coumns that go up and down. A period on the periodic table are the rows that go horizontal or across.
How many grops are there in the periodic table?
Groups of the Periodic Table are defined as vertical colums. There are 18 groups in the periodic table.
