Electronegativity increases from left to right across a period and decreases down a group.
There are 7 periods in the modern periodic table.
The modern periodic table contains approximately 118 elements.
The modern periodic table is based on the atomic number of elements, which is the number of protons in the nucleus of an atom. Elements are arranged in order of increasing atomic number, which helps to group elements with similar properties in columns called groups or families.
Dmitri Mendeleev is credited with developing the modern periodic table in 1869. He arranged the elements based on their atomic mass and chemical properties, predicting the properties of undiscovered elements. Mendeleev's table laid the foundation for the periodic table we use today.
7 periods and 18 groups are there on the modern periodic table.

The modern periodic table is modified form of the mossleys periodic table,which was yet modifiied form of the mendileevs periodic table,which was based on the principle-atomic mass is the periodic function of the elements.Mossley changed the periodicity of elements to be the periodic functions of their atomic numbers.hence in the modern periodic table we can find,the repeatation of certain properties of elements after definite intervals and hence the periodic table has groups and periods the elements inside which,are similar.this is possible because across a period electrons increase by 1,keeping shells sama,and down a group,outer electrons remain same,but shells increase by1.
There are 7 periods in the modern periodic table.
The modern periodic table has seven periods.
Yes.The modern periodic table is organized by atomic number. The elements properties are found to be periodic.

The modern long form of periodic table was constructed by Neils Bohr based on modern periodic law proposed by Moseley.
The modern periodic law states that, The properties of the elements are the periodic function of there atomic number not atomic weights.
