8 electrons.
a mass number of 17
This isotope may be lithium-8.
The atom must have 8 electrons to make it have a neutral charge
The atomic number of an element is the number of protons in each atom of the element, whether neutral or not. If the atom is neutral, the number of electrons in the atom is the same as the number of protons.
They're not always neutral. It's the atom's goal to be, though. Since the atomic number is 8, it should have 8 electrons to be neutral. The protons are always locked in the nucleus and the number doesn't change. The number of protons is what makes an atom what it is.
There are 8 electrons in a single neutral oxygen atom.The atomic number of oxygen is 8, because it has 8 protons in its nucleus. In an elemental, neutral, atom of oxygen the number of electrons will match the number of protons. There are 8 electrons in a neutral oxygen atom.Note that oxygen can become an ion under certain circumstances, and we need to specify the neutral atom to state how many electrons there are in oxygen.
If it is neutral, there would be equal protons and electrons. However, if it is a charged ion, then there could be more or less electrons than protons. For example, 8 protons and 7 electrons would give +1 charge. 8 protons and 10 electrons would give -2 charge. Each proton has a +1 charge. Each electron has -1 charge.

8 protons
oxygen atom has 8 protons and 8 neutron's. since they 8 protons they also have 8 electrons in there neutral state.
The atomic number of an element is the number of protons in each atom of the element, whether neutral or not. If the atom is neutral, the number of electrons in the atom is the same as the number of protons.
Oxygen's atomic number is 8. Thus it has 8 positively charged protons per atom. In order for oxygen to be neutral, it must also have 8 negatively charged electrons in each atom.
as many protons as they have.
There are eight electrons in the neutral form of the atom with the atomic number eight (oxygen or O). --- Answer 2: 8. The atomic number represents the number of protons (positive charge) in an atom. For the atom to have a neutral charge, there must be 8 negative charges in the shells around the nucleus of the atom.
They're not always neutral. It's the atom's goal to be, though. Since the atomic number is 8, it should have 8 electrons to be neutral. The protons are always locked in the nucleus and the number doesn't change. The number of protons is what makes an atom what it is.

There are 8 electrons in a single neutral oxygen atom.The atomic number of oxygen is 8, because it has 8 protons in its nucleus. In an elemental, neutral, atom of oxygen the number of electrons will match the number of protons. There are 8 electrons in a neutral oxygen atom.Note that oxygen can become an ion under certain circumstances, and we need to specify the neutral atom to state how many electrons there are in oxygen.
If it is neutral, there would be equal protons and electrons. However, if it is a charged ion, then there could be more or less electrons than protons. For example, 8 protons and 7 electrons would give +1 charge. 8 protons and 10 electrons would give -2 charge. Each proton has a +1 charge. Each electron has -1 charge.
The mass number is the number of protons and neutrons added together. Electrons are not counted as part of the mass because while protons and neutrons weigh the same, Electrons weigh virtually nothing compared to them. As far as I can tell, there is no stable atom with a mass of 8.
