Comprehension given below is followed by some multiple choice questions. Each question has one correct option. Choose the correct option. In the modern periodic table, elements are arranged in order of increasing atomic numbers which is related to the electronic configuration. Depending upon the type of orbitals receiving the last electron, the elements in the periodic table have been divided into four blocks, viz s, p, d and f. The modern periodic table consists of 7 periods and 18 groups. Each, period begins with the filling of a new energy shell. In accordance with the Aufbau principle, the seven periods (1 to 7) have 2, 8, 8, 18, 18, 32 and 32 elements respectively. The seventh period is still incomplete. To avoid the periodic table being too long, the two series of f-block elements, called lanthonoids and actinoids are placed at the bottom of the main body of the periodic table (iv) The electronic configuration of the element which is just above the element with atomic number 43 in th same group is ...........

In the long or modern form of the periodic table, the element in the periodic table have been divided into four blocks, s-p-d -and f -. Each period begins with the filling of new energy shell. Two series of f -block elements are placed at the bottom of the periodic table. Which of the element whose atomic numbers are given below cannot be accommodated in the present set-up of the modern periodic table?

Consider the section of the periodic table given below. Note : In this table B does not represent boron C does not represent carbon F does not represent fluorine H does not represent hydrogen K does not represent potassium You must see the position of the element in the periodic table. Some elements are given in their own symbol and position in the periodic table, while others are shown with a letter. With reference to the table: Draw the electron dot structure for the compound formed between C and K.
