Valence Electrons
when a neutral atom loses an electron it becomes a positive ion. it now has a stable outer most shell.
The electron configuration is why they react. The Alkali metals have one electron in their outer shell and to complete their outer shell need 7 more electrons. They can give, take or share electrons with other atoms. This is when the Halogens come in handy. The Halogens have 7 electrons in their outer shells, and need one more to complete the outer shell. These can react very easily because they have both the perfect amounts to fill their outer shells and become compounds. Other atoms with other amounts to become atoms not ions needs another element to react with. Hope this helps, Matt.
No, on the most inner shell, only 2 electrons can be held, but then on every other shell it is usally 8
The electrons placed near the nucleus.
The electrons in the valence shell are those most concerned with bonding and how that occurs. The "non-bonding" electrons are the ones in the inner shells, or the non-valence shells of an atom. Non-bonding electrons are also found in the valence shell. They are referred to as lone pairs. For example, in ammonia (NH3), nitrogen has one lone pair. In most circumstances, lone pair electrons do not form bonds (they do in a special type of covalent bond).
Electrons in the outer most shell are called Valence Electrons.
The outer most electron shell of iodine atom contains 7 electrons.
Valence electrons
In a neutral carbon atom, there will be 4 electrons in the outer most valence shell.
The electrons in the outer most shell are known as the valence electrons.
Valence electrons
The valence shell is the outer most shell or imaginary orbit of an atom containing <8 electrons. The electrons in this shell are called 'valence electrons'.
The valence shell is the outer most shell or imaginary orbit of an atom containing <8 electrons. The electrons in this shell are called 'valence electrons'.
The outer shell of an atom, also known as the valence shell, can hold a maximum of eight electrons. This is based on the octet rule, which states that atoms are most stable when they have eight electrons in their outer shell. However, the first shell can hold only two electrons.
An atom is most stable and unreactive when it has eight electrons in its outer shell, a configuration known as the octet rule. This is because having a full outer shell typically leads to lower energy and greater stability. However, helium is an exception, as it is stable with just two electrons in its outer shell.
A fluorine atom has seven unshared electrons in its outer most shell (valence shell).
There is a total of 8 electrons that are needed to fill outer shell of most atoms. An atom is the smallest unit of matter.
