6
An oxygen atom has eight electrons. The first electron shell can contain two electrons so that shell is filled leaving six electrons left. Since the second electron shell can contain up to eight electrons, the remaining six electrons go into the second shell. Since the second shell is the outermost shell, there are six electron's in the outer energy level.
it has 6 electrons in the outer most shell
Electrons in the outermost electron shell have the most energy in an atom. The energy of an electron increases as it moves further away from the nucleus. Electrons in the innermost shell have the least energy, while electrons in the nucleus have the highest energy due to their proximity to the protons.
Oxygen has two electron shells because it has eight electrons in total, with two in the first shell and six in the second shell. Atoms tend to fill their outermost electron shell to achieve stability, and oxygen does this by sharing electrons with other atoms or gaining electrons to fill its outer shell.
There are 2 electrons in the outermost shell of strontium. Strontium has an electron configuration of [Kr] 5s^2, indicating that it has two electrons in its outermost shell.
There are 5 electrons in the outermost electron shell of a phosphorus atom. Phosphorus has the electron configuration 2-8-5, so it has 5 electrons in its outermost shell.
There are 5 electrons in the outermost electron shell of a phosphorus atom. Phosphorus has an electron configuration of 2, 8, 5.
On the outermost (or valence) electron shell.
Valence.
Normally, three.
The electrons in the outermost shell or orbital are called valence electrons. These electrons are involved in forming chemical bonds with other atoms.
An octet of electrons is when the outermost electron shell of an atom contains eight electrons.
