78, lead has atomic number of 82
A Co3+ ion has lost three electrons from its neutral state, so it has 23 electrons.
An Mg2+ ion has lost two electrons, resulting in a total of 10 electrons. Magnesium normally has 12 electrons but when it forms a 2+ ion, it loses two electrons.
A sodium ion with the symbol Na+ has 10 electrons. Sodium normally has 11 electrons, but when it loses one electron to form a Na+ ion, it has 10 electrons.
A cesium ion with a +1 charge (Cs+) has lost one electron. Cesium (Cs) normally has 55 electrons, but the Cs+ ion has 54 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.
The H+ ion has no electrons.
A Co3+ ion has lost three electrons from its neutral state, so it has 23 electrons.
Lead forms the Pb2+ ion, as lead has an atomic number of 82, the Pb2+ ion has 80 electrons in total
Lead lose two electrons and silver lose one electron.
An Mg2+ ion has lost two electrons, resulting in a total of 10 electrons. Magnesium normally has 12 electrons but when it forms a 2+ ion, it loses two electrons.
A sodium ion with the symbol Na+ has 10 electrons. Sodium normally has 11 electrons, but when it loses one electron to form a Na+ ion, it has 10 electrons.
A cesium ion with a +1 charge (Cs+) has lost one electron. Cesium (Cs) normally has 55 electrons, but the Cs+ ion has 54 electrons.
it should lose 3 electrons
The ion carbon C4+ has 6 protons and 2 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.
There are 10 electrons in Mg2+ because the atomic number of magnesium is 12, which means it normally has 12 electrons. When it forms a 2+ ion, it loses 2 electrons, leaving 10 electrons in the Mg2+ ion.
A lead ion with 78 electrons indicates that it has lost some of its electrons, as the neutral atomic number of lead (Pb) is 82, meaning it normally has 82 electrons. The difference of 4 electrons results in a net positive charge of +4. Therefore, the net charge of the lead ion would be +4.
