To figure out which element it is, look at the protons. The number of protons are the atomic number, which you can find on the Periodic Table. In this case, 8 protons is Oxygen. You also know that it's negatively charged, because there are more electrons than protons. Because there are 2 more electrons, it would have a charge of -2.

Is an ion with 8 protons and 10 electrons positively charged?
Protons are positively charged and electrons are negatively charged. An ion with 8 protons and 10 electons would have a charge of 2- as there are 2 more electrons than protons.As this ion has 8 protons is must have an atomic number of 8 (oxygen) so the species in question is O2-.If an ion has more protons than electrons it will be positively charged.
When you subtract the number of electrons from the number of protons what do you get?
It should be:# of protons - # of electronsIt gives you the ion charge of the element. For example, Oxygen ion has 8 protons and 10 electrons. Therefore, 8 - 10 = -2 ----> O2-
How many electrons are in a -2 anion that has 8 protons and 8 neutrons?
Such an anion contains 10 electrons. it is called the oxide ion.
How many neutrons are in the atom of oxygen -18?
8
What would you need to tell the number of protons and electrons present in an ion?
The atomic number of the element in the ion, when there is only one such element, and the atomic charge on the ion. For example, in Na+1, the atomic number is 11; this gives the number of protons. The number of electrons is equal to the atomic number minus the charge on the ion, in this instance, 10 electrons. If the sign on the ion is negative, as in O-2, remember that subtracting a negative number is equivalent to adding the positive number of the same magnitude. Thus, oxygen has an atomic number of 8, and 8 - (-2) equals 10 electrons.
How many protons are in an oxide ion?
There are 8 protons and 10 electrons in an oxide ion.

If An ion has 8 protons 9 neutrons and 10 electrons the symbol for the ion is?
17O2-
What ion has 8 protons 9 nuetrons and 10 electrons what is the name of the ion?
O-2
How many protons are in the ion O2?
The neutrons and protons in the nucleus do not change when electrons are removed from an atom. Even when two electrons are removed. Oxygen has several isotopes, with 8 protons and either 8, 9, or 10 neutrons... all representing stable isotopes. 8 neutrons is most common on Earth.
What is the total charge on an oxygen ion that has 8 protons 8 neutrons and 10 electrons?
Consider an atom of oxygen in which the nucleus contains 8 protons and 8 neutrons. If it is doubly ionized, what is the charge of the oxygen ion and how many electrons remain in the ion?
If eight protons are found in the nucleus of a -2 ion how many electrons are there?
Since the 8 protons contribute a net charge of +8 and the net ion is -2, then: +8p + -xe- = -2 x = 10 Therefore there are 10 electrons, forming a O-2 ion.
What happens to an atom when it has 8 electrons?
It has 8 electrons. And if its not an ion, then it has 8 protons.
How many electrons are in a -2 anion that has 8 protons and 8 neutrons?
Such an anion contains 10 electrons. it is called the oxide ion.
What is the net charge of o?
An Oxygen atom has 8 protons and 8 electrons 1 Proton = +1 8 protons = +8 1 electron = -1 8 electrons = -8 Net charge = 0 Oxygen ion has 8 protons and 10 electrons 8 protons = +8 8 electrons = -10 Net charge = -2
How many protons neutrons and electrons are in a oxygen ion with a charge of negative two?
Every atom, ion, and isotope will have 8 protons. The oxygen ion will have 2 more electrons than protons to achieve a full outer shell.
