The atomic number of an element is 71. is this element diamagnetic or paramagnetic?
2 answers:
Answer:
Paramagnetic
Explanation:
Paramagnetic are those which has unpaired electrons and diamagnetic are those in which all electrons are paired.
Given the atomic number - 71
The electronic configuration is -
The electron in 5d orbital = 1
This 1 electron will be unpaired as electron is first singly filled.
<u>Thus, the element is paramagnetic as the electron is unpaired.</u>

<h3>Further explanation</h3>Writing electron configurations starts from the lowest to the highest sub-shell energy level. There are 4 sub-shells in the shell of an atom, namely s, p, d, and f. The maximum number of electrons for each sub-shell is
• s: 2 electrons
• p: 6 electrons
• d: 10 electrons and
• f: 14 electrons
Charging electrons in the sub-shell uses the following sequence:
<em>1s², 2s², 2p⁶, 3s², 3p⁶, 4s², 3d¹⁰, 4p⁶, 5s², 4d¹⁰, 5p⁶, 6s², etc. </em>
The element is Oxgen, with symbol O, and :
the atomic number=8=number of electron
the atomic mass=16
The electron configuration based on the number of electrons(for Oxygen=8), so the configuration :
or we can write with noble gas [He] 2s²2p⁴
