-3 electrons are gained,i.e,3 electrons are lost by Al and 3 electrons are gained by the other atom nearby.
If Ag+ is converted to Ag, it has gained electrons. Ag+ indicates that silver has lost one electron, so when it is converted back to Ag, it means that electron has been gained back.
One electron was lost to form Cu+ from the neutral Cu atom.
A Co3+ ion has lost three electrons from its neutral state, so it has 23 electrons.
Calcium normally has 20 electrons. Because it has a plus 2 charge, it must have two less electrons. Therefore, the calcium ion has 18 electrons.
chlorine atom has 17 electrons when it accepts one more it becomes chloride ion so chloride has total 18 electrons, isoelectronic with Argon.
If Ag+ is converted to Ag, it has gained electrons. Ag+ indicates that silver has lost one electron, so when it is converted back to Ag, it means that electron has been gained back.
One electron was lost to form Cu+ from the neutral Cu atom.
The number of electrons is 10.
19 Protons and 20 electrons
The H+ ion has no electrons.
This cation has 24 electrons.
11 protons and 10 electrons
It has 4 d electrons.
Pb2+ has lost two electrons, so it has 82 - 2 = 80 electrons.
51
CArbon has an atomic number of 6. There are therefore only 2 electrons in C4+
Mn has 25 protons.
