Valence electrons are the amount of electrons in the outermost electron shell. 8 valence electrons fill the outer shell making it completely stable.
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.
there is no such element
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.
all elements from group 16 or the chalcogens (oxygen, sulphur, selenium, tellurium and polonium)
Chlorine.
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.
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.

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.

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.
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.
No, an atom with six electrons will try to react with another atom to gain two more electrons. Actually the fewer electrons the atom needs the more reactive it will be unless it has exactly eight valence electrons in its outer shell like a noble gas(He, Ne, Ar, etc.) Hope this helps!
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.
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).
