Ionic bonding is when atoms either give away or take electrons. You do not need an outer shell.

What is a chemical bond formed by?
Chemical bonds are formed by sharing of electrons between two atoms. Atoms tend to achieve electronic configuration of their respective inert gases i.e. in the outer shell they need to have 8 electrons. e.g. Sodium has 1 electron in the outer shell by donating it it is left with electronic configuration of 2, 8. and Chlorine which has 7 electrons in its outer shell receives 1 electron and gets electronic configuration 2,8,8. Between Sodium and Chlorine ionic bond is formed and NaCl is produced. Chemical bonds are formed by sharing of electrons between two atoms.

Why do noble gases not normally form compounds?
Noble gases have a full outer shell, meaning that they have no valence electrons and have 8 electrons in their outer shell. If the outer shell is full they do not need electrons, so they would not want to bond with another element to form a compound.
Will neon and lithium bond with each other?
No, neon already has 8 electrons in its outer shell. Why would it need more?
How do atoms or ions combine to form molecules?
They can do this in many ways, most commonly through either ionic and covalent bonds. usually metals will bond with non metals through ionic bonds. non metals will bond with non metals through covalent/molecular bonds. it all depends on the valency electrons. an example of a ionic bond is sodium (Na) and Chlorine (Cl). sodium has 1 electron in its outer shell and chlorine has 7 electrons in its outer shell. they both want to be stable and have a full outer shell. so sodium will give its one electron to chlorine (now sodium has a full outer shell) and chlorine will receive this electron and will now have 8 electrons in its outer shell (full outer shell now).... the compound is now sodium chloride and its written like this: NaCl.in covalent bonds non metals can share electrons to be stable. the most common example is two hydrogen atoms. they both have 1 shell with 1 electron in it. since the first shell only needs 2 to fill, they both need 1. so they will share this 1 electron they both have to form a full outer shell. it will look like this:H . + H . = H : Hsee how at the end both has 2? even though they are shared. this is a covalent bond.Source(s):im in year 10
Does phosphorus and chlorine form an ionic bond?
The outer shell on phosphorus (P) has 5 electrons -- it needs 3 electrons The outer shell on chlorine (Cl) has 7 electrons -- it needs 1 electron The electronegativity of P is about 2.2 The electronegativity of Cl is about 3.2 -- it will attract electrons slightly more So the simplest arrangement here is: PCl3 (P shares three electrons, and each Cl shares one.) They are just sharing electrons (covalent bond). If the electronegativities were a little stronger (delta of 1.7 is the magic number), then you could have an ionic bond -- but in this case both atoms need electrons, so ionic bonding wouldn't occur with P and Cl.
How are electrons involved in chemical bonding?
In chemical bonding, there is either a transfer of electrons from one atom to another(ionic bond) or a sharing of electrons between 2 or more atoms(covalent bond) In chemical bonding, there is either a transfer of electrons from one atom to another(ionic bond) or a sharing of electrons between 2 or more atoms(covalent bond)
Why do noble gases usually dont form chemical bonds?
Their outer energy shell is full of electrons and so it does not need to form a bond to fulfil this.
How many valence electrons are needed to achieve a full outer shell?
It depends, most atoms need 8 total valence electrons in their outer shell (some need 2). So subtract the number they have (determined by the group that the element is in) from 8 and that is how many they need to fill their outer shell!
Why do the sodium ion and the chloride ion form an ionic bond instead a covalent bond?
because they can each get a full valence shell by combining electrons, and have no need to share with other elements. (NA gives away one electron, giving it eight in its valence shell, and CL gains that electron, which also makes its valence shell eight).
What do non metals do to achieve a full outer electron Shell?
The nonmetals usually gain or share however many electrons they need to complete their outer shell. Metals tend to lose the electrons in their outer shell, so that one of the inner shells essentially becomes the outer shell.
Is FeCl3 ionic or covalent bonding?
Two of them is present here.to build cl3 it needs covalent bond and to build fecl3 it need ionic bond.
What is a good sentence using the word ionic bond?
example: When two unstable valence electrons need to become stable, they form an ionic bond.
