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.
Do metals contain fewer valence electrons?
No, metals typically have fewer valence electrons compared to nonmetals. Valence electrons are the outermost electrons in an atom, involved in bonding and determining the reactivity of an element. Metals tend to have fewer valence electrons which allows them to easily lose electrons and form positive ions.
What element has more valence electrons that oxygen fewer valence electrons that neon more protons than sodium but fewer protons than argon?
there is no such element
What element has more valence electrons than oxygenfewer valence electorns than neon more protons than sodium but fewer protons than argon?
Neon has 0 valence electrons so it is not possible to have an element with fewer valence electrons. There can, therefore, be no such element.
What element has two fewer valence electrons than noble gases?
all elements from group 16 or the chalcogens (oxygen, sulphur, selenium, tellurium and polonium)
Why is boron an exception to the octet rule?
Boron is an exception to the octet rule because it only has six electrons in its outer shell, so it can form stable compounds with fewer than eight electrons. This occurs because boron is in the second row of the periodic table and can form stable compounds by sharing fewer electrons.
Valence electrons found where?
Valence electron are found in the outer shell of an atom. Depending on the number of valence electrons, the atom is more or less stable: fewer => less stable and more => more stable (inert). Stable = less likely to react with other atoms.

Why does boron not need an octet in its valence shell?
Boron does not need an octet in its valence shell because it is an exception to the octet rule due to its electron configuration and bonding behavior. Boron typically forms stable compounds with fewer than eight electrons in its outer shell.
Do metals contain fewer valence electrons?
No, metals typically have fewer valence electrons compared to nonmetals. Valence electrons are the outermost electrons in an atom, involved in bonding and determining the reactivity of an element. Metals tend to have fewer valence electrons which allows them to easily lose electrons and form positive ions.
What is an incomplete octet?
An incomplete octet refers to a situation in which an atom has fewer than eight electrons in its valence shell. This is commonly seen in elements such as beryllium (4 electrons) and boron (6 electrons) which can form stable compounds despite not having a full octet.
What element has more valence electrons than oxygenfewer valence electrons than neon more protons than sodium but fewer protons than argon?
Neon has 0 valence electrons so it is not possible to have an element with fewer valence electrons. There can, therefore, be no such element.
How boron atoms will follow octet rule and why?
Boron atoms do not follow the octet rule. This is because boron typically forms compounds with fewer than 8 electrons around it due to its atomic structure. Boron forms stable compounds by sharing electrons in covalent bonds and can have as few as 6 electrons in its valence shell.
What element has more valence electrons that oxygen fewer valence electrons that neon more protons than sodium but fewer protons than argon?
there is no such element
Where are valence electrons found?
Valence Electrons are the electrons that are located furthest away from the atom itself in the outermost electron shell. They are located on the last energy level also known as the valence level.
How many bonds does carbon usually from?
4. Carbon has 4 valence electrons and it rarely forms ionic compounds or compounds with fewer than 4 bonds (though it's possible).
What element has more valence electrons than oxygenfewer valence electorns than neon more protons than sodium but fewer protons than argon?
Neon has 0 valence electrons so it is not possible to have an element with fewer valence electrons. There can, therefore, be no such element.
