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.

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.
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.
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.
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 atomic number is the number of protons and therefore, assuming the atom is neutral, the number of electrons. You would need to additionally know the atomic mass to figure out the number of neutrons.
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

The number of protons can not be changed in an atom, while the number of electrons can be.
In a neutral atom, the number of electrons will be the same as the number of protons. This is because one positive proton will cancel out one negative electron; therefore, if the atom is neutral, it must have the same number of protons and electrons.The number of protons is also the same as the atomic number. For this example, Bromine, with the atomic number of 35, has 35 protons.Bromine:Atomic number- 35Number of protons- 35Number of electrons- 35The mass number is the sum of the atomic number (or number of protons/electrons) and the neutrons. For this example, we know the atomic number (35) + # neutrons = mass number (80). To figure out the number of neutrons, take the mass number and subtract the number of electrons/protons/atomic number. Mass number (80) - atomic number (35) = neutrons (45).
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.
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.
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.
An ion, which would have a positive charge if there are more protons, and a negative charge id there are more electrons.
