QUESTION:
A neutral atom of a certain element has 17 electrons. Without consulting a periodic table, (a) write the ground-state electron configuration of the element, (b) classify the element, (c) determine whether this element is diamagnetic or paramagnetic.
ANSWER:Step 1 of 3
(a) The increasing order of energies of the orbital are,1s, 2s, 2p, 3s, 3p, 4s, 3d, 4p, 5s, 4d, 5p, 4f, 5d, 6p, 7s...
Here, as subshell accommodates maximum 2 electrons, p subshell accommodates maximum 6 electrons and d subshell accommodates maximum 10 electrons.
Since 17 electrons are present, electronic configuration is,
