A6 In the modern Periodic Table, elements are arranged in the order of increasing proton numbers. A student tried to re-arrange the elements in the order of increasing relative atomic masses and got nearly the same arrangement.However, the elements, argon and potassium would have their positions...
In modern periodic table, the element with atomic numberZ=118will be: View Solution Which of the following statements (s) about the modern periodic table are incorrect ? (i) The elements in the modern periodic table are arranged on the basis of their decreasing atomic numbers ...
thus getting the valence shell closer to the nucleus. This makes it difficult to remove electrons. But as we move down the group, the number of orbits keeps on increasing along with the number of electrons. The distance from the nucleus coupled with the interference of ...
Step by step video, text & image solution for In the modern period table, elements are arranged in order of increasing atomic number which is related to the electric configuration. Depending upon the type of orbitals receving the last electron, the elements in the periodic table have been div...

2 The Periodic Table we currently use is derived from that proposed by Mendeleev in 1869 after he had noticed patterns in the chemical properties of the elements.Use the third period of the modern Periodic Table, sodium to chlorine, to answer the following questions.(a)(i) Describe how the...
Q.In the modern periodic table, how does the atomic size of the elements vary along the period and down the group? Explain. Q. How many groups and periods are there in the modern periodic table? How do the atomic size and metallic character of elements vary as we move: ...
