Metals tend to lose electrons to attain Noble Gas electron configuration. Groups 1 and 2 (the active metals) lose 1 and 2 valence electrons, respectively, because of their low Ionization energies. Non-metals are limited to the elements in the upper right hand corner of the Periodic Table.

How are valence electrons related to stability?
Valence electrons are the outermost electrons in an atom, and they determine the atom's chemical properties. Atoms with a full valence shell of electrons tend to be stable because they have a lower energy state. Atoms will gain, lose, or share electrons to achieve a full valence shell, which increases their stability.
An atom does not easily lose or gain electrons if it has?
A full outer electron shell. Atoms tend to be more stable when they have a full valence shell, which typically contains eight electrons. This stability makes it less likely for the atom to either lose or gain electrons.
What is an oxidation number and how is it related to Valence Electrons?
An oxidation number is a measure of the charge that an atom would have if the bonding were ionic. It indicates the number of electrons that an atom would gain or lose in a chemical reaction. Valence electrons are the outermost electrons in an atom’s electron cloud and play a key role in determining the oxidation number of an atom.
How many electrons must phosphorus p gain or lose to have 8 valence electrons?
Phosphorus wants to gain three electrons to have 8 valence electrons.
How valence electrons affects reactivity?
Valence electrons determine how easily an atom can bond with other atoms. Atoms with a few valence electrons are more likely to lose or gain electrons to achieve a stable electron configuration, making them more reactive. The number of valence electrons also influences the type of chemical bonds an atom can form with other atoms.
What is the name of electrons in the outermost shell that an atom can gain lose or share with another atom?
A Fluorine atom has an atomic number of 9. Draw out the electron shell diagram for Fluorine. Is a Fluorine atom more likely to gain, lose or share electrons to fill its valence shell?
What is the name of electrons in the outer most shell that an atom can gain lose or share with another atom?
Electrons in the outer most shell are called Valence Electrons.
How with 4 valence electron will achieve a full set of valence electron?
An atom with 4 valence electrons will have to either gain 4 electrons or lose 4 electrons to achieve a full set of eight electrons.
When an atom of magnesium forms an ionic bond with an atom of oxygen which will gain electrons?
Magnesium has a charge of 2+ and oxygen 2- Magnesium will lose the two "extra electrons" in its valence shell when creating an ionic bond with oxygen. The oxygen will gain these two electrons.

How many electrons phosphorus must gain or lose to have 8 valence electrons?
Phosphorus wants to gain three electrons to have 8 valence electrons.
Why do atoms form positive ions and others form negative ions?
It is a matter of how full an atom's outer or valence shell of electrons is. For most atoms, the most stable setup is one with a full shell of 8 valence electrons, and an atom will gain or lose electrons to achieve this. For atoms with close to 8 valence electrons, such a chlorine (7 valence electrons, it is generally easier to gain electrons and thus become negatively charged. For atoms with few valence electrons, such as sodium (1 valence electron), it is easier to lose electrons and go down to the next lowest shell, which is already full.
What is the number of electrons a phosphorus atom must gain or lose to have 8 valence electrons and what is the resulting ion charge?
A phosphorus atom has 5 valence electrons and needs to gain 3 more to achieve a total of 8 valence electrons. By gaining 3 electrons, phosphorus becomes negatively charged, resulting in a charge of -3. Therefore, the resulting ion is a phosphide ion (P³⁻).
