Depends on the atom. Between one and eight electrons. There is a method to it. The elements on the very two first rows have one (H) and two (He). Over on the right side
(Boron) of the elemental chart are three to eight electrons respectively.
You mean valence electron? 2 If your talking about Bohr Diagrams then it depends on the metal
Oxygen needs 2 more valence electrons to have a full outer shell. Oxygen has 6 valence electrons, and a full outer shell for oxygen is achieved at 8 valence electrons.
You can determine the number of electrons in the outer energy level of an atom by looking at its group number on the periodic table. For main group elements, the group number corresponds to the number of valence electrons. For example, group 1 elements have 1 valence electron, group 2 elements have 2 valence electrons, and so on.
Antimony has 5 valence electrons.
Fluorine needs 8 valence electrons to have a filled outer energy level, following the octet rule. Fluorine naturally has 7 valence electrons, so it only requires one more electron to achieve a stable octet configuration.
7 electrons are on the outer (valence) shells of all halogens
There are 2 electrons in the inner level, 8 electrons in the middle level, and exactly 6 electrons in Sulfurs outer level.
In a neutral carbon atom, there will be 4 electrons in the outer most valence shell.
Sulfur has 6 outer valence electrons.
There are different numbers of valence electrons in different elements.

2 valence electrons
4V V-Valence Electrons Valence Electrons-Last electron (which is on the outer shell)
Cesium, or Cs, has 1 valence electron.
Valence electrons are the electrons in the outer energy level. Each period shares many similar characteristics, one of which being the amount of electrons in the outer energy level. If you are unfamiliar, the Periods are the Vertical Columns, and Families are the Rows. I hope this helps you.
the outer shell of cobalt contains 9 electrons.
Oxygen needs 2 more valence electrons to have a full outer shell. Oxygen has 6 valence electrons, and a full outer shell for oxygen is achieved at 8 valence electrons.
