they're are zero unpaired electrons.
In the element bromine (Br), there is only 1 unpaired electron. It has 7 valence electrons, so 3 pairs, plus an unpaired electron.
In an oxide ion, electrons get added. This means, lesser nuclear charge. This is due to screening effect. The inner electrons shield the outer electron from the nuclear charge which is why the outer electrons get relatively lesser nuclear charge. So, more electrons means lesser nuclear charge. Consider a person standing in front of you. You get blocked from the view in front of you. Suppose two more people stand in front of you. Now, it is more difficult for you to catch a glimpse of the front view than it was before. This is exactly what happens in the oxide ion. Lesser nuclear charge means the electrons do not get pulled towards the nucleus as they were before, i.e., in the oxide ion, the electrons do not get pulled towards the nucleus as they were in the neutral oxygen atom.So, the electrons will be farther than they originally were.Thus, an oxide ion is larger than an oxygen atom.
Yes, Chlorine is a paramagnetic element. The electron configuration of Chlorine is 1s(2)2s(2)2p(6)3s(2)3p(5) which contains an unpaired electron in the 3p orbital. Atoms with unpaired electrons are said to be paramagnetic.
A chlorine ion is monatomic ― it is just Cl-.
None.Calcium loses 2 electrons to form an ion.

5 unpaired electrons There are 5 unpaired electrons in the Fe3+ ion. The reason for this is that Iron has the electron configuration Ar3d5.

There are zero unpaired electrons in a ground-state magnesium ion (Mg2+). It has lost two electrons, resulting in a filled electron shell.
Iron-III (Fe3+) has 5 unpaired electrons. Each Fe3+ ion has five 3d electrons that are unpaired.
All of the electrons are paired. If you are asking how many lone pairs, there are 4.
The number of unpaired electrons in Tl-81 ion is zero, this in case of ejection of one electron from Tl-81 atom. Thx!!
4 unpaired in high spin 2 unpaired in low spin
In the Fe^3+ ion, there are 5 unpaired electrons. This is because the Fe atom has 5 electrons in its 3d orbitals that remain unpaired when it loses 3 electrons to form the Fe^3+ ion.
An oxide ion has 8 protons. This is because it is an oxygen atom that has gained 2 electrons to become negatively charged. The number of protons remains the same as the number of protons in a neutral oxygen atom.
In the element bromine (Br), there is only 1 unpaired electron. It has 7 valence electrons, so 3 pairs, plus an unpaired electron.
Paramagnetism arises from the presence of unpaired electrons in an atom or molecule. When an element or compound has one or more unpaired electrons, it will be attracted to an external magnetic field, exhibiting paramagnetic properties. The greater the number of unpaired electrons, the stronger the paramagnetic behavior observed.
