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.
if O atom has 8e- , 8p+, & 8 n
then O-2 ion is 10e-, 8p+, & 8 n
The oxide ion O2- has 8 protons and 10 electrons.
It is Oxide ion having 8 protons but 10 electrons, the extra 2 electrons are responsible for 2- charge.
8 in O and 16 in O2
Eight protons in this ion.
There are 8 protons and 10 electrons in an oxide ion.
The ion S(2-) has 16 protons and 18 electrons.
By seeing how many protons to electrons there are. More protons, the Ion is positive. More electrons, the Ion is negative.
Be2+ ion has 4 protons and 2 electrons
9 protons
Eight protons in this ion.
O2- ion has a total of 10 electrons.
how many protons does the carbonate ion have?
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-
There are 8 protons and 10 electrons in an oxide ion.
The number of protons present in an ion is equivalent to its atomic number.
7 protons
The number of protons is 7.
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.
The ion S(2-) has 16 protons and 18 electrons.
it has 8 protons
CO3 Carbon - 6 protons Oxygen - 8 protons 6 + (8*3) = 30 protons. Therefore carbonate ion has 30 protons.
