all of them
there is no such element
Calcium oxide (CaO) consists of calcium (Ca) and oxygen (O). Calcium, a group 2 element, has 2 valence electrons, while oxygen, a group 16 element, has 6 valence electrons. Therefore, in total, CaO has 2 (from Ca) + 6 (from O) = 8 valence electrons.
Oxygen-16 has 6 valence electrons because it is in Group 16 of the periodic table, also known as the oxygen family or the chalcogens. Each oxygen atom contributes 6 valence electrons.
An oxygen atom has two valence electrons.
all elements from group 16 or the chalcogens (oxygen, sulphur, selenium, tellurium and polonium)
All have six valence electrons.
it is in the oxygen family and has 6 valence electrons it requires 2 electrons
Oxygen is the element that has 8 valence electrons and is in the gaseous state at room temperature.

Oxygen has 2 electrons in the innermost orbital and 6 in the outermost (valence) orbital.
There are 6 electrons in the valence shell of the oxygen family. This includes elements like oxygen, sulfur, selenium, and tellurium. These elements all have 6 valence electrons because they belong to group 16 (or 6A) of the periodic table.
The element described has more valence electrons than oxygen but fewer than neon, more protons than sodium but fewer than argon. This element is magnesium, which has 12 protons, 12 valence electrons (2 more than oxygen but 2 less than neon), and is situated between sodium and argon on the periodic table.
O - Oxygen has 6 valence electrons.
Oxygen-16 has 6 valence electrons because it is in Group 16 of the periodic table, also known as the oxygen family or the chalcogens. Each oxygen atom contributes 6 valence electrons.
No, oxygen has 8 electrons in general (in neutral form) but only has 6 valence electrons.
An oxygen atom has two valence electrons.
