Modern Periodic Table, also known as the Periodic Table, is
a tabular arrangement in which chemical elements are arranged according to their atomic numbers, configuration of electrons and chemical properties
. A Modern Periodic Table consists of four block, i.e., the “S”, “P”, “D” and “F” blocks.
What is the modern periodic table based on?
The modern periodic table is based on
the periodic law
: “The chemical properties of elements are a periodic function of their atomic number.” Let’s see how is this different from Mendeleev’s periodic table and how this solves for its predecessor’s limitations.
What is the definition of modern periodic table?
The modern periodic table is
used to organize all the known elements
. Elements are arranged in the table by increasing atomic number. In the modern periodic table, each element is represented by its chemical symbol. The number above each symbol is its atomic number. … Rows of the periodic table are called periods.
What is modern periodic table short answer?
In the modern periodic table,
the elements are arranged in the order of their increasing atomic number
. In the modern periodic table, there are seven horizontal rows called periods and eighteen vertical columns (1 to 18) called groups. The arrangement of the periods and groups results in formation of boxes.
What is the modern periodic table called?
The modern table is called
‘long form’ of the periodic table
. On the basis of electronic configuration, how will you identify the first and the last element of a period?
What are the main features of modern periodic table?
Main features:
Each column is called a group. All elements in a group have similar chemical and physical properties because they
have the same number of outer electrons
. Periods – In periodic table elements are arranged in a series of rows. Elements of the same period have the same number of electron shells.
What are the advantages of the modern periodic table?
- It is easier to remember the properties of an element if its position in the periodic table is known.
- The periodic table has made the study of chemistry systematic and easy. …
- The type of compounds formed by an element can be predicted by knowing it position in the periodic table.
How can I memorize the periodic table?
- Memorize chunks of five elements at a time. You’ll have 23 separate groups of five to learn, with a few left over. …
- Recite the element names out loud. …
- Space out your learning sessions. …
- Aim to overlearn.
Who is the father of modern periodic table?
Internet search giant Google has dedicated a Doodle to Russian
chemist Dmitri Mendeleev
on his 182nd birth anniversary. Born on February 8, 1834, Mendeleev is popularly known as the “Father of Periodic Table”.
Who gives modern periodic table?
In 1869,
Russian chemist Dmitri Mendeleev
created the framework that became the modern periodic table, leaving gaps for elements that were yet to be discovered. While arranging the elements according to their atomic weight, if he found that they did not fit into the group he would rearrange them.
Which is the shortest period in periodic table?
First period
of periodic table is shortest period.
What is group and period in periodic table 10?
In the modern periodic table, elements are arranged in order of their increasing atomic numbers. Explanation of Modern Periodic Table: Elements are arranged in order of their increasing atomic numbers.
The vertical columns are
known as groups and horizontal columns are known as periods; in the modern periodic table.
How many groups are there in periodic table?
Groups are numbered from 1 to 18. From left to right in the periodic table, there are
two
groups (1 and 2) of elements in the s-block, or hydrogen block, of the periodic table; ten groups (3 through 12) in the d-block, or transition block; and six groups (13 through 18) in the p-block, or main block.
Why is it called periodic table?
Why is the periodic table called the periodic table? It is called the periodic table
because of the way the elements are arranged
. You’ll notice they’re in rows and columns. The horizontal rows (which go from left to right) are called ‘periods’ and the vertical columns (going from up to down) are called ‘groups’.
What is group and period in periodic table?
The columns of the periodic table are called groups. Members of the same group in the table have the same number of electrons in the outermost shells of their atoms and form bonds of the same type. The
horizontal rows are
called periods.
Where is me on the periodic table?
