Valence electrons are the electrons least tightly held by the atom and by definition are the electrons in the outermost shell of the electron and are highest in energy. They are the electrons that often contribute to an elements reactivity and in the case of Sodium, which as one valence electron in its ground state, it "gives up" its electron when it comes in contact with water.
What else can I help you with?
The valence electrons are those electrons most tightly held by the atom?
Valence electrons are the electrons in the outermost energy level of an atom, and they are involved in bonding with other atoms to form molecules. These electrons are most loosely held by the atom, as they are farthest from the nucleus and have the highest energy.
Electrons that are held most loosely in an atom are called what?
The electrons in the valence band, this can be 1 to 8 electrons (in the s and p orbitals of the outer shell) depending on the element.
If the outer electrons of the atom of substance are held tightly to the atom you would expect that substance would be .?
an insulator
Valence electrons are those?
Valence electrons are the electrons in the outermost energy level of an atom. They are involved in chemical bonding and determining an element's reactivity.
Describe how the atoms in water are held together.?
Each hydrogen atom is bonded to the oxygen atom in a covalent bond, in which they share valence electrons.
What parts of an atom participate in chemical reactions?
Electrons are the parts of an atom that participate in chemical reactions. Specifically, it is the outermost electrons, known as valence electrons, that are involved in forming chemical bonds with other atoms.
Is it true the valence electrons are those electrons most loosely held by the atom?
yes it is true, they are the outermost electrons and sometimes get "stolen" by other elements creating an ion
What is the outer most energy level of an atom?
This is the valence shell and is involved in bonding e.g. the sharing or loss of electrons to form a molecule or giant structure. Inner shells do not take part in bonding though their shielding effect and repulsion does affect the loss and gain of electrons from this shell.
Why are the valence electrons of an atom the only electrons likely to be involved in bonding to other atoms?
Valence electrons are the electrons in the outermost shell of an atom, and they are the ones involved in forming chemical bonds because they have the highest energy and are most easily shared or transferred with other atoms to achieve a stable electron configuration. Inner electrons are typically held more tightly by the nucleus and thus less likely to participate in bonding.
Is the valence electron farthest or closest to the nucleus?
No. By definition, valence electrons are the furthest electrons from the nucleus in the atom. They are the electrons most easily removed from (or added to) the atom to create ions. A loophole to this answer might be to say that hydrogen and helium only have 1 and 2 electrons respectively so their valence electrons are close. That's a matter of perspective, as no electrons are really "close" to the nucleus to begin with. A typical comparison is to imagine a grape seed in the middle of a football stadium. The grape seed represents the nucleus, and an electron would be a speck of dust on the outside of the stadium.

How is it possible that sodium has more volume than neon when neon has more valence electrons?
Although neon has more valence electrons than sodium, the size of an atom is primarily determined by the number of electron shells. Neon's higher nuclear charge causes its valence electrons to be held more tightly, resulting in a smaller atomic size. Sodium, with fewer valence electrons, has a larger atomic size due to less nuclear charge and more electron shells.
What is the energy level farthest away from the nucleus of the atom that holds 8 or more valence electrons?
The valence electrons of an atom are those electrons that are in its outer energy shell or that are available for bonding. The electrons more loosely held by the nucleus - are the ones that are gained, lost or shared.
