Aluminium 3+(Al3+)
NO!!! 8 protons , means 8 positive charges ( 8+). 10 electrons , means 10 negative charges ( 10-). Summing 8+ 10 - = 2- So the ion will have a charge of '2-' From the information given this is the oxygen ion ( O^(2-)).
The number of electrons are required to predict the charge of the ion.
Since oxygen is not a metal, its ions are not normally written with Roman numbers suffixed, but an oxide ion, with formula O-2, contains 10 electrons.
An aluminum ion, Al3+, has 10 electrons. This is because aluminum normally has 13 protons and 13 electrons in a neutral atom, but in the +3 ion it loses 3 electrons, leaving it with 10 electrons.
Neutrons-12 Protons -12 Electrons-10
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.
The symbol for the ion with 8 protons, 9 neutrons, and 10 electrons is ^17O.
There are 11 protons in an ion with 10 electrons and a -1 charge. The charge of an ion is defined by the difference between the number of protons and electrons. In this case, since the ion has a -1 charge, it means there is one more electron than the number of protons.
NO!!! 8 protons , means 8 positive charges ( 8+). 10 electrons , means 10 negative charges ( 10-). Summing 8+ 10 - = 2- So the ion will have a charge of '2-' From the information given this is the oxygen ion ( O^(2-)).
9 protons
The number of electrons are required to predict the charge of the ion.
Cl-1 has 17 protons and 18 electrons
The ion Na+ has 11 protons, 12 neutrons, and 10 electrons. This is because sodium has an atomic number of 11, meaning it naturally has 11 protons and 11 electrons, but as an ion with a +1 charge, it has lost 1 electron.
The ion would have a positive charge equal to the difference between the number of protons and electrons. For example, if there are 10 protons and 8 electrons, the ion would be a 2+ charged ion.
Mg2+ cation
Since oxygen is not a metal, its ions are not normally written with Roman numbers suffixed, but an oxide ion, with formula O-2, contains 10 electrons.
A nitrogen ion -3 has 7 protons and 10 electrons. This is because nitrogen normally has 7 protons and 7 electrons, but the -3 charge indicates that it has gained 3 electrons to become negatively charged.
