What are second period elements ?
Lithium and magnesium are showing similar properties, so second-period elements are known as Bridge elements

See lessWhat is Mosley’s periodic law?
According to Mosley's periodic law, the physical and chemical properties of elements are periodic functions of their Atomic number.
According to Mosley’s periodic law, the physical and chemical properties of elements are periodic functions of their Atomic number.

The correct answer is Bridge Element.
The correct answer is Bridge Element.
See lessBrief about modern periodic table?
The 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. AtomicRead more
The 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.
See lessIn the modern periodic table, each element is represented by its chemical symbol. The number above each symbol is its atomic number. Atomic numbers increase from left to right and from top to bottom in the table.
Rows of the periodic table are called periods. From left to right across a period, each element has one more proton than the element before it.
Columns of the periodic table are called groups. Elements in the same group have similar properties.
All elements can be classified into one of three classes: metals, metalloids, or nonmetals. Elements in each class share certain basic properties. From left to right across each period of the periodic table, elements change from metals to metalloids to nonmetals.
Brief about the first periodic table ?
The First Periodic Table: In the 1860s, a scientist named Dmitri Mendeleev also saw the need to organize the elements. He created a table in which he arranged all of the elements by increasing atomic mass from left to right across each row. When he placed eight elements in each row and then startedRead more
The First Periodic Table:
In the 1860s, a scientist named Dmitri Mendeleev also saw the need to organize the elements.
See lessHe created a table in which he arranged all of the elements by increasing atomic mass from left to right across each row.
When he placed eight elements in each row and then started again in the next row, each column of the table contained elements with similar properties. He called the columns of elements groups.
Mendeleev’s table is called a periodic table and the rows are called periods. That’s because the table keeps repeating from row to row, and periodic means “repeating.”
What are periods in periodic table?
Each of the tables has horizontal rows is called periods.
Each of the tables has horizontal rows is called periods.
See lessWhat is group in periodic table?
Each of the tables has a vertical row is called groups.
Each of the tables has a vertical row is called groups.
See lessWhat number of elements are provided in the modern periodic table?
The correct answer is 118 elements
The correct answer is 118 elements
See lessExplain the electron structure in groups in periodic table ?
Elements having the same number of outer electrons are put in the same group of the periodic table. When we move down a group, new shells get added. The outermost shell has electrons present for bonding. Though the number of shells increases as we go down in a group, the number of electrons in the oRead more
Elements having the same number of outer electrons are put in the same group of the periodic table.
See lessWhen we move down a group, new shells get added.
The outermost shell has electrons present for bonding.
Though the number of shells increases as we go down in a group, the number of electrons in the outermost shell remains the same.
Explain the electron structure in periods in periodic table?
Elements are arranged in increasing the atomic number of elements in a period. One extra electron gets added to the outermost shell as we move along the periods from left to right. The electron gets added to the same shell or orbit and thus the electrons present for bonding increase by one unit. ThuRead more
Elements are arranged in increasing the atomic number of elements in a period.
See lessOne extra electron gets added to the outermost shell as we move along the periods from left to right.
The electron gets added to the same shell or orbit and thus the electrons present for bonding increase by one unit.
Thus, the shell number remains the same but the number of electrons present for bonding increases along a period.
