eight electrons
Xenon has 8 valence electrons.
The maximum number of electrons in the second energy level of an atom is 8.
Eight
2 or more electrons, because Oxygen already has 8.
The most valence electrons an atom can contain is eight.
The second shell can hold eight electrons.
4
Every oxygen atom has eight electrons.
The number of protons in an atom is equal to the number of electrons in the atom. Therefore, the total number of electrons in an atom can be found by determining the atom's proton number. For example, the proton number of oxygen is eight. Thus, an oxygen atom has eight protons and eight electrons.
Every oxygen atom has eight electrons.
