Why do some atom gain electrons to form ions and some lose electrons?

it depends upon factor how an atom can gain the stability. The atoms tend to reach the nearest Noble gas electronic configuration (octet- 8 electrons in outer most shell except Helium) , the atoms having less then 4 electrons in outer most shell usually lose the electrons ( cation formation), having more than 4 accept the electron (anion formation) and having 4 electrons in outermost shell form the covalent bonds by sharing of electrons.

Atoms of groups 1 elements have only 1 electron in their outer shells, which means to stabilize themselves it is easier for them to give this one atom away, rather than trying to gain 7 more. Once they have given the electron away there are more protons than electrons in the atom and so the atom become positively charged: a cation.
The reverse of this applies for group 17 - it is easier for them to gain electrons, thus becoming negatively charged and an anion.

∙ 12y agoAtoms of group1 elements lose electrons because they have a low ionization energy; therefore it is easier for other elements, with a high electronegativity, to pull the single electron away from the group1 atom's valence shell rather than the element in group1, which has a low electronegativity, to pull an electron away from another atom.
Atoms of group 17 gain electrons because they have a high electronegativity. Because of their high electronegativity, it is easier for these elements to pull an electron away from another atom. They do not lose electrons because of their high ionization energy.
Ionization energy is the energy required to remove an electron.
Electronegativity is the tendency to attract electrons.

∙ 13y agoThey lose their electrons to become Ions because they have alot of outer shell and as a result, alot of electons. Think of a nucleus of an atom like the positive end of a magnet... The electrons are the negative end and opposites attract... The further away you place two magnets, the weaker the pull... It is the same with the Alaki Metals (group 1)... This is why they are very reactive metals, because their outer shells are further away from the nucleus meaning it's easier for an electron to find the energy to escape, because the nucleus has a weaker pull on it...

∙ 11y agoGroup 1 elements have only 1 valence electron. Losing that electron gives the cation that forms a noble gas configuration, making it stable. Group 17 elements have 7 valence electrons and need only one more to have a noble gas configuration and become stable as an anion.
Wiki User
∙ 9y agoThe atoms in Group 17 elements gain electrons to form anions because they are trying to get 8 electrons in their valence shells. If they gain an extra electron they will have an octet.

How do you find the charge of an atom with 7 valence electrons?
The halogens, group 17, have 7 valence electrons. When they form ions, they gain 1 more valence electron and become ions with a charge of 1-.
How can you get a negatively charged ion?
When atoms lose or gain electrons, they are called ions. As electrons are negatively charged, it is when they gain electrons that they become negative ions, if they lose electrons they become positive ions. They can also form ions in pairs. for example sodium atom (NA) gives up it's outer electron and becomes an NA+ ion. the chlorine atom (CL) picks up the spare electron and becomes a CL- ion.
What is the name of the bond that takes place when the atom's electrons give or gain electrons?
Ionic bonding- the transfer of electrons from one atom to another. This results in ions, as the atoms which gain/lose electrons now have a charge.
How do positive and negative ions forms?
Atoms gain electrons to form negatively charged anions. Atoms lose electrons to form positively charged cations.
The type of ion that forms when atoms gain electrons?
Atoms that gain electrons are called anions, and atoms that loose electrons are called cations
What determines whether an atom forms a positive or negative charge in an ionic bond?
If an atom is electropositive (metals, in general), then they will lose electrons and form positive ions. If an atom is electronegative (non-metals, in general), then they will gain electrons and form negative ions.
Do isolated atoms form ions spontaneously?
No, the atom would have to be in an environment where it could gain or loose electrons.
Cations form when an atom gains electrons?
Cations are positive ions, so an atom is supposed to lose electrons to become a cation. Anions are formed when an atom gains electrons.
Will the valence electrons of calcium give or take away electrons?
Calcium atom will generally lose two electrons to form Ca2+ ions. Calcium will not accept (gain) electrons.
Why some atoms gain or lose electrons to form ions.?
if an atom gains or loses electrons, it is no longer has an equal number of electrons and protons. Because the charges do not cancel completely, the atom has a net electric charge.
Negative ions form when atoms-blank-valence electrons?
Negative ions form when atoms GAIN valence electrons.
How do you find the charge of an atom with 7 valence electrons?
The halogens, group 17, have 7 valence electrons. When they form ions, they gain 1 more valence electron and become ions with a charge of 1-.
How can you get a negatively charged ion?
When atoms lose or gain electrons, they are called ions. As electrons are negatively charged, it is when they gain electrons that they become negative ions, if they lose electrons they become positive ions. They can also form ions in pairs. for example sodium atom (NA) gives up it's outer electron and becomes an NA+ ion. the chlorine atom (CL) picks up the spare electron and becomes a CL- ion.
What ions are formed in nonmetals?
Non-metal atoms gain an electron, or electrons, from another atom to become negatively charged ions.
What is the name of the bond that takes place when the atom's electrons give or gain electrons?
Ionic bonding- the transfer of electrons from one atom to another. This results in ions, as the atoms which gain/lose electrons now have a charge.
When atoms lose or gain electrons they from?
When atoms lose or gain electrons, they form ions. These are charged particles.
What is the particle that an antom can loose or gain in order to form into a charged iron?
Atoms can lose or gain electrons. When they do, they form charged particles called ions: if an atom loses one or more electrons, it becomes a positively charged ion, I think ;]
