Which of these following will be in increasing order in the modern periodic table?
No of neutrons
All of these
Pd has exceptional outer electronic configuration as 4d10 5s0, it belongs to
period, group 11
period, group 10
period, group 16
period, group 9
The electronic configuration of an element is 1s22s22p63s23p3
What is the atomic number of the element which is just below the above element in the periodic table?
d and f-block
s and p-block
p and d-block
Representative elements belong to:
d- and f- block
s- and p- block
Which of the following statements related to the modern periodic table is incorrect?
The p-block has 6 columns, because a maximum of 6 electrons can occupy all the orbital in a p-shell.
The d-block has 8 columns, because a maximum of 8 electrons can occupy all the orbital in a d-sub shell.
Each block contains a number of columns equal to the number of electrons that can occupy that sub shell.
The block indicates value of Azimuthal quantum number (l) for the last sub shell that received electrons in building up the electronic configuration.
