There is no atom or element that has one proton, one neutron and ten electrons. Duterium has one proton, one neutron and one electron (in a neutral atom). Tritium has one proton, two neutrons and one electron (in a neutral atom), but that is the closest. In any neutral atom the number of electrons will equal the number of protons in the nucleus of that atom. An atom with one proton in its nucleus and 10 electrons just isn't possible.
A sulfide ion (S2-) has 16 protons. This is because the sulfide ion carries a charge of -2, indicating that it has gained two extra electrons, and thus has 16 protons in its nucleus as the number of protons always determines the element.
Any atom with 8 protons is an oxygen atom. Seven neutrons makes it a particular isotope of oxygen, and nine electrons means that it is an ion, with a charge of minus one. This is unusual because oxygen tends to form ions with a charge of minus two, not minus one, but it isn't impossible.
In neutral atoms (with the same number of protons and electrons), the number of protons and electrons equal the atomic number. If our atom has 9 electrons, is neutral, and therefore has 9 protons, it is element #9: Flourine, which has an atomic mass of 19: 9 protons plus 10 neutrons.
The equation for nitrite is NO2-. To find the valence electrons of each atom, count how many groups from the left of the periodic table (skipping over the d-block, which is shown in this picture in the related link. So Nitrogen has 5, and each oxygen has 6. The negative sign means that the polyatomic ion has one extra electron, so 1 more. 5+(6*2)+1=18 total valence electrons.
No, iron has 26 electrons. It has an atomic number of 26, indicating the number of protons and electrons in a neutral atom.
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.
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-)).
An oxygen ion with a charge of -2 has 8 protons, 10 neutrons, and 10 electrons. The number of protons and neutrons remains the same as a regular oxygen atom (8 and 8, respectively), but the number of electrons increases by two to accommodate the charge.
O-2
The total charge on an oxygen ion with 8 protons and 10 electrons is +2, because oxygen normally has 8 protons and 8 electrons, resulting in a neutral charge. Adding 2 extra electrons gives a net charge of -2.
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.
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.
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.
The net charge of an oxygen ion is typically -2. In its neutral state, oxygen has 6 protons and 6 electrons, giving it a net charge of 0. When it gains 2 electrons to become an ion, it carries a net charge of -2.
It has 8 electrons. And if its not an ion, then it has 8 protons.
A -2 anion indicates that the ion has gained two extra electrons. Since there are 8 protons in the nucleus (8 electrons in a neutral atom), adding two extra electrons would give a total of 10 electrons in the anion.
