8 electrons
An atom with atomic number 8 corresponds to oxygen. Oxygen has 8 electrons because the number of electrons in an atom is equal to its atomic number.
Every oxygen atom has eight electrons.
Every oxygen atom has eight electrons.
There are 6 electrons present outside the nucleus of an oxygen atom. Oxygen has an atomic number of 8, which indicates the number of protons and electrons in a neutral atom. Since the atomic number of oxygen is 8, it has 8 electrons, with 2 in the inner shell and 6 in the outer shell.
Eight, the atomic number of oxygen.
Oxygen's atomic number is 8. That means an atom of oxygen always has 8 protons. To stabilize it then, it must also have 8 electrons.
An atom with an atomic number of 20 has 20 electrons. The number of electrons in an atom is equal to its atomic number.
An oxygen atom with a mass number of 15 has 8 protons, 7 neutrons, and 8 electrons. The atomic number of oxygen is 8, which indicates the number of protons and, in a neutral atom, also the number of electrons. The number of neutrons can be calculated by subtracting the atomic number from the mass number (15 - 8 = 7).
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.
8
The atomic number of an element tells you the amount of of electrons. In oxygen, symbol 'O', there are 8 electrons since the atomic number is 8. For example, the atomic number of Hydrogen is 1, so there is 1 electron in a Hydrogen atom.
The number of protons is equal to atomic number; in a neutral atom the number of electrons is also equal to the numbers of protons.
