Does 4 valence electrons lose or gain?
Group IV A atoms have four valence electrons to be stable these atoms can lose four or gain four electrons to achieve stability. Losing 2 electrons can create a filled s subshell. This electron configuration is not as stable as losing 4 but is found in nature.
Do valence electrons gain or lose electrons?
The amount of electrons an element will tend to gain or lose depends on the number of electrons in the atom’s valence shell. An atom will always try to ionize to its stable state with the transfer of the fewest electrons possible. It can either lose four electrons or gain four electrons to get a full valence shell.
Can an element lose 4 electrons?
Answer: If an element has 4 electrons in its outermost shell , then it may be 4 lose electrons or gain electrons to make outermost shell octet. So , it depends on an atom that it may lose or gain electrons to make its outermost shell octet.
Can valence electrons be gained?
Some atoms have nearly eight electrons in their valence shell and can gain additional valence electrons until they have an octet. When these atoms gain electrons, they acquire a negative charge because they now possess more electrons than protons.
How many valence electrons are needed to form an ion?
When forming ions, elements typically gain or lose the minimum number of electrons necessary to achieve a full octet. For example, fluorine has seven valence electrons, so it is most likely to gain one electron to form an ion with a 1- charge. We can use this method to predict the charges of ions in ionic compounds.

How are valence electrons arranged in an atom?
Valence electrons are all arranged in different orbitals or shells and are mostly negatively charged particles. Further, these electrons are responsible for interaction between atoms and the formation of chemical bonds. However, not all electrons are associated with the atom.
Why are elements with eight valence electrons considered stable?
Elements with eight valence electrons are considered stable, and largely do not react with other elements or form bonds. This is why elements bond together. By sharing electrons, each can reach a stability un-achievable on its own. The kind of bond formed by sharing electrons is called a covalent bond.
Which is an example of a valence electron?
One example is Carbon. It has 4 valence electrons, so it can make a 4+ or a 4- charge. But because of its relatively stable half filled orbital, most of the time it takes part in covalent bonding like in organic molecules. On occasion, Carbon can ionize, most commonly 4+.
