How many electrons does potassium need to gain or loose to become more stable?

Potassium (K), an Alkali Metal in Group 1 with atomic number 19, has a single valence electron in its outermost shell. Therefore it only needs to lose one electron in order for the element to become stable.

What is the valence?
the combining capacity of an atom is called valency
Is the valency equal to ionic charge of an atom?
Yes, it is. Since valency is the no. of electrons an element should gain or loose or share to become stable. So, this is true in case of substances which form ions. But elements like carbon never form ions. Its valency is four. It shares electrons to get stable.
Do non metals loss electrons or gain?
Remember M.A.L.E and M.I.PMetalAtomsLoseElectronsMetalIonsPositiveHowever, non-metals gain electrons when forming ionic bonds, in order to gain a stable electron configuration. Because they gain electrons, they form negatively charged ions.
How many electrons must the oxygen atom lose to be stable?
Oxygen wants to gain 2 electrons, so its charge would be 2-, because electrons have a negative charge.
Why is it easy for a metal to loose an electron?
Metals useually have few valence electrons and they loose electrons from their outermost shell thus, forming an ion with positive charge (cations). This is because it is easy for metals to loose electron and attain stable or octet configuration similar to rare gases. Hence to attain stability metals lose valence electrons. E.g. sodium (At no. =11 ; electronic configu-1s2, 2s2, 2p6, 3s1) metal has one valence electron and it is easy for it to loose 1e rather to gain 7e to attain stable configuration. Hence it loose 1e forming Na+ cation.
Do metals usually gain or loose electrons to be stable?
Metals will LOSE electrons to become stable.
How many electrons must beryllium loose to become stable?
Beryllium is a stable element.
What happens when there are too few electrons?
All the atoms in the universe have a tendency to become stable by having 2 or 8 electrons in their outermost cells. So, if an atom has very few electrons i.e 1,2,3 or 4 electrons in it's outermost cell it will tend to loose electrons in order to become stable. hope it helps!

Does pottassium (k) gain or lose electrons?
Potassium is more likely to lose its electron to become a positive ion.
Why can't neon loose electrons?
Neon is stable in nature. It has completely filled octet.
If metals loose electrons to non metals are metals now anions?
No, it is not true. When metals loose electrons they become cations.

When atoms become ions their outer most shells of electrons become?
they add or loose electrons from the outer most shells
Is anodized aluminum nonreactive?
Yes is is non reactive because of the electrons that are on the exterieur energetique layers of its atome. The attomique number for aluminum is 13 meaining it has 3 valence electrons ( 3 electrons on its outer layer). When an element does not have a completed exterieur energetic layer it is unstable, so it tries to gain electrons or loose electrons to become stable ( to be stable you need to have 8 electrons on the outer layer). So in this case aluminum wants to become stable, by loosing three electrons, but the ponostrophic energy required to loose them is to high, so it basicly gives up until it can react with a moleculos element, which is a whole different topic.
What is the reason noble gases don't become ions?
Noble gases have eight electrons in their outermost (valence) shell (an octet)and due to this they are very stable so they don't need (or want) to loose or gain electrons to be stable and thus don't take part in chemical reactions and don't form any negative or positive ions.
How will sodium and chlorine become stable?
Sodiumbeing in group 1 needs to loose 1e- to become stable. Chlorine being from group 17 needs to gain 1e- to become stable. Sodium gives its extra electronto the chlorine atom. Now both have 8 electrons in their valence and are stable. The sodium gets a positive charge because it lost and electron. The chlorine gets a negative charge because it gained an electron.This creates an ionic bond
