8 valence electrons
elements, or atoms, do not have valence numbers, they have valence orbitals (the outermost one) or valence electrons (all the electrons in the outermost orbital). you can look this up anywhere that shows the electron configuration, like your periodic table.
Oxygen (O2) is a diatomic element with a bond between the atoms. It forms a covalent bond, where the two oxygen atoms share electrons to achieve a more stable electron configuration.
It is called a valence shell electron. The number of valence shell electrons atoms of an element have can be read off the periodic table: Those in group one have one valence electron, those in group two have two etc. Thus, elements in the same group have the same number of valence shell electrons and so, similar chemical properties.
Two. One hydrogen atom has one valence electron, so two hydrogen atoms will have two valence electrons :)
A valence electron, also known as valence orbital, is basically composed of electron and atoms that can make a chemical bond. Valence electrons identify other elementÕs chemical properties to determine if the element may bond with other elements.
Two sodium atoms are needed to provide the 2 electrons necessary to complete the valence octet of an oxygen atom. Sodium typically loses one electron to achieve a stable electron configuration, which can then be transferred to an oxygen atom to satisfy its electron needs.
Atoms with 1 valence electron are typically found in Group 1 of the periodic table, known as the alkali metals. Examples include lithium, sodium, and potassium, all of which have one valence electron in their outermost energy level. This lone valence electron makes these elements highly reactive.
Serine has five valence electrons. It has three valence electrons from the oxygen atom and one valence electron each from the carbon and nitrogen atoms in its structure.
the element with seven valence electrons will be more reactive. The reason for this is that elements want to always want to have a full valence shell (they always want 8, like a noble gas). The element with eight valence electron is happy with its full shell and will not want to get rid of any electrons.
This is a chemical element. You can find the how many electron in a single atom by using a periodic table.
Hydrogen contains one valence electron (one electron in its outer orbit) and oxygen contains six valence electrons, to become stable a element wants to have 8 electrons in its outer orbit. Therefore when hydrogen and oxygen combine, it will take 2 parts hydrogen and one part oxygen H2O
Aluminum has 3 valence electrons.

Three atoms that have eight valence electrons are oxygen, neon, and argon. These atoms have a full outer electron shell, making them stable and less likely to form chemical bonds.
