Question

Chemistry : the atomic number of an element is 73. Is this paramagnetic or diamagnetic? :) ...?

Answer 1

paramagnetic

Step-by-step explanation:

Paramagnetic are those which has unpaired electrons and diamagnetic are those in which all electrons are paired.

Given the atomic number - 73

The electronic configuration is -

`1s^22s^22p^63s^23p^63d^(10)4s^24p^64d^(10)5s^25p^64f^(14)5d^36s^2`

The electrons in 5d orbital = 3

These 3 will be unpaired as electrons are first singly filled.

Thus, the element is paramagnetic as the electrons are unpaired.

Answer 2

Paramagnetic, an easy way to check is to see if it is the last element within the orbital and you can do that simply by looking at the periodic table. The s orbital has two, the p has 6 so on and so forth. Some elements are considered diamagnetic if they are almost completely full.
