What is valence shell of electrons?
Valence shell is outermost shell of an atom.It cannot hold more than 8 electrons.
What has more valence electrons than oxygen?
All halogen elements have 7 valence electrons (group 17): F, Cl, Br, I, At.
Why k shell has low energy than valence shell?
AnswerK-shell electrons generally have much larger binding energies than valence shell electrons. Can you give me a specific example or some more information to clarify your question? is energy level depend on electrons, i means is the shell having more electrons have more energy?
Does neon or oxygen have more valence electrons?
Neon has more valence electrons than oxygen. Neon has a full outer shell with 8 valence electrons, while oxygen typically has 6 valence electrons.
Element that has more valence electrons than oxygen fewer valence electrons than neon more protons than sodium but fewer protons than argon?
The element in question is magnesium. It has 12 protons (more than sodium and less than argon), 2 more valence electrons than oxygen (which has 6), and 8 fewer valence electrons than neon (which has a full valence shell with 8 electrons).
What is valance shell expansion?
Valence shell expansion refers to the phenomenon where elements from the third row and below on the periodic table can exceed the octet rule by utilizing d orbitals in addition to s and p orbitals to accommodate more than eight electrons in their valence shell. This allows these elements to form more than the usual number of bonds and have expanded valence shells.
Why is atom of sulfur smaller than an atom of silicon despite sulfur having more mass?
Because as you add more electrons to the same valence shell, the effective nuclear charge increases and thus holds the valence shell closer.
Why is an atom of sulfur smaller than an atom of silicon despite sulfur having more mass?
Because as you add more electrons to the same valence shell, the effective nuclear charge increases and thus holds the valence shell closer.
What is more stable K or Kr?
Kr (krypton) is more stable than K (potassium) due to its full valence shell of electrons, which provides greater stability. Potassium is a highly reactive metal that readily loses its single valence electron, making it more chemically reactive and less stable than krypton, which is a noble gas with a full valence shell.
When an atom or an ion has 8 valence electrons it is more or less stable than when it ha fewer than eight valence electrons?
When an atom or ion has 8 valence electrons, it is generally more stable, as it fulfills the octet rule. This stability is due to achieving a full outer electron shell, which is energetically favorable. Atoms or ions with fewer than 8 valence electrons may be more reactive, as they tend to gain or lose electrons to achieve a full octet.
Why does an atom with only one electron in its valence shell make a better conductor than an atom with seven electrons in its valence shell?
An atom with only one electron in its valence shell is more likely to lose that electron easily, making it a better conductor. In contrast, an atom with seven electrons in its valence shell is more stable and less likely to lose electrons, thus making it a poor conductor.
Valence electrons are present in more than one what?
Valence electrons are present in more than one energy level or shell around an atom's nucleus. They are the electrons involved in chemical bonding and determining the reactivity of an element.
