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.
You could describe it as neutral as the charge of the protons cancels out the charge of the electrons, essentially though it is just a normal atom as if the number of protons was different to the number of electrons, it would be classed as an ion.
The number of protons in an atom is equal to its atomic number. In a neutral atom, the number of electrons is equal to that of protons. If the atom is negatively charged, add it to the number of electrons; and if positive, subtract.
This would be magnesium, based on the number of protons. Since the protons is equal to the number of electrons it is a neutral atom. Given the number of protons in the atom, the isotope would be magnesium-26.
There would be a total of 27 electrons because the total number of protons are 29 so to make the ion more positive the would have to be less electrons than protons.Read more: How_many_protons_and_electrons_does_a_copper_ion_with_a_charge_of_2_have
I would say 6 because C-12 has 6 protons, and the number of protons is equal to the number of electrons. This is a rare exception when the protons, neutrons, and electrons are all the same number-6.
The number of electrons is the same as the number of protons or the atomic number. If the element is an ion of e.g O+2, you would take away 2 from the atomic number and if it is O-2, you would add two electrons

Atomic number means number of protons present in an atom. Atomic number= number of protons. mass number = number of neutrons+ number of protons. So if you subtract the number of protons you get neutrons and if you subtract neutrons you get protons. mass number - protons= neutrons Mass number - neutrons = protons.

Ions are charged particles therefore ions must always have an unequal number of Protons and Electrons. Since the amount of protons, in general, can't change, then the amount of charge is controlled by how much electrons are present. E.g., If there is 7 protons and 7 electrons, the charge is 0 as the protons cancelled out the electrons. However if it gained 3 electrons, it would be 7 protons and 10 electrons and therefore have a charge of -3 (Because electrons are negatively charged)
The number of protons can not be changed in an atom, while the number of electrons can be.
8 protons 8 electrons and 8 neutrons. Oxygen has the atomic number 8, so it has 8 protons, 8 electrons. The number of neutrons would be mass number-atomic number, so 15.9994-8=7.9994, so rounding would be 8 neutrons.
I would say 6 because C-12 has 6 protons, and the number of protons is equal to the number of electrons. This is a rare exception when the protons, neutrons, and electrons are all the same number-6.
There can not be an atom with more electrons than protons, however to find the atomic mass of any atom disregard the electrons and add the number of protons and nuetrons together. The previous answer is correct in that the atomic mass is equal to the number of protons plus the number of neutrons. The atomic number is the number of protons and in a neutral atom the number of protons and electrons are equal. Atoms have can have a charge, they are then called ions. The way the become charged is either through the loss (oxidation) or gain (reduction) of electrons. Therefore it is possible to have a charged atom with more or less electrons than protons.
An ion, which would have a positive charge if there are more protons, and a negative charge id there are more electrons.
