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 elements C) determine whether the element is diamagnetic or paramagnetic.

Solutions

Expert Solution

n = 17 then Z = 17

this is chlorine, a hallogen

Electron config:

[Ne] 3s2 3p5

This configuratio nwill have 1 unpaired e-

Since there is an unpaired electron, Cl atoms are paramagnetic, this is weak
