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.
Why is it easier to remove an electron from sodium atom than a chlorine atom?
It is easier to remove an electron from a sodium atom than from a chlorine atom because sodium has a single valence electron in its outer shell, which is more loosely held and experiences less effective nuclear charge. In contrast, chlorine has seven valence electrons and a higher effective nuclear charge, meaning its outer electrons are held more tightly. Consequently, removing an electron from sodium requires less energy compared to chlorine.
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.
What determines whether or not an atom will loose its valence electrons?
An atom's tendency to lose its valence electrons is primarily determined by its electronegativity and ionization energy. Atoms with low ionization energy, typically found in groups 1 and 2 of the periodic table (like alkali and alkaline earth metals), readily lose their valence electrons to achieve a more stable electron configuration. Additionally, the atomic size plays a role; larger atoms have valence electrons that are farther from the nucleus and are less tightly held, making them more likely to be lost. Overall, the balance of these factors influences an atom's reactivity and ability to form positive ions.
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.
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.
