can you explain me what is periodicity and mendeleevs periodic law ? Please dont ask me to follow any link!!!!!
In context of chemistry, periodicity refers to trends or recurring variations in element properties with increasing atomic number. periodicity is caused by regular and predictable variations in element atomic structure.
Mendeleev's periodic law states that " physical and chemical properties of elements are periodic function of their atomic masses".
it means in Mendeleev 's periodic table elements are arranged according to their atomic masses whereas in modern periodic table elements are arranged according to their atomic number.
In mendeleev 's periodic table there are 8 groups and 6 periods. in mendeleev 's periodic table if any new elements are discovered then it can be placed in 7th period as he left some space in between while arranging the elements..
