+4 On the Periodic Table, all elements are neutral. And that is the key to this problem.
Lead (Pb) on the periodic table has an atomic number of 82. Therefore it has 82 protons. How many electrons would it need to be a neutral atom then? Obviously, 82! So if we have 82 electors and 82 protons we have neutral lead, but we don't have 82 electrons we only have 78. Therefore neutral lead lost negatively charged electrons. When you lose a negative you become more positive.
So we have a charge of +4, since 82-78=4.
In general the solution to this problem is:
(Atomic Number) - (Number of Electrons) = (Net Charge)
This is the ion Th4+
A sodium atom has 11 electrons so the total charge of all the electrons in a sodium ion is -10.
because the number of protons (which have a positive charge of +1) and the number of electrons (which have a negative charge of -1) are the same. when number of protons = number of electrons, overall charge = 0
They have an equal numbers of electrons and protons...MoMMy =)
It would have a negative charge. It would be a negative ion with a 2+ charge.Remember: when an atom gains electrons they become NEGATIVE.when an atom loses electrons they become POSITIVE.
A lead ion with a charge of +4 has lost 4 electrons from its neutral state. Lead typically has 82 electrons in its neutral state, so a lead ion with a +4 charge would have 78 electrons.
Pb which is neutral has 82 electrons. Thus, if it has a 4+ charge, then it has 78 electrons.
When it has no charge there are 78.the number of electrons is always equal to the number of protons, both are the atomic number. the atomic number of platinum is 78, so 78 electrons and 78 protons too.
There are 78 protons and 78 electrons present in a platinum atom. There are also at least 114 neutrons in the five stable isotopes. 192 Pt = 114 194 Pt = 116 195 Pt = 117 196 Pt = 118 198 Pt = 120
Natural lead is an electrically neutral atom. Thus, when it loses 4 electrons it loses 4 units of negative charge. This gives the lead ion 4 units of positive charge, or Pb4+.
Lead will always have 82 protons. If it has a 2+ charge, that means there are 2 more protons than electrons, so there are 80 electrons.
78 protons and 78 electrons
The ion with 82 protons and 80 electrons is a doubly charged ion of lead (Pb2+). The presence of 80 electrons instead of the expected 82 results in a net positive charge of 2, indicating that 2 electrons have been lost.
Electrons charge is a negative
Lead nitrate is an ionic compound. Lead has a 2+ charge and nitrate has a 1- charge, so they attract each other through ionic bonds, where electrons are transferred from lead to nitrate.
A shortage of electrons on a surface creates an electric charge imbalance or positive charge. This can lead to the attraction of electrons from neighboring surfaces to balance the charge and create an electric field.
The atomic number of platinum is 78. So there are 78 protons and 78 electrons.
