∙ 6y agoit 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.

∙ 11y agoBy doing so, both end up having a noble gas configuration, with 8 valence electrons (known as an octet). They do this to become chemically stable. They become stable as they have filled their outer shell 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.

∙ 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.

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-.
When atoms lose or gain electrons and become positively or negatively charged, they form ions. Positively charged ions are called cations, while negatively charged ions are called anions.
Atoms gain electrons to form negatively charged anions. Atoms lose electrons to form positively charged cations.
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.
A negatively charged ion forms when an atom gains one or more electrons. This causes an imbalance between the number of protons (positive charge) and electrons (negative charge), resulting in an overall negative charge on the ion.
Negative ions form when atoms gain extra electrons to fill their valence shell. This results in the atom becoming negatively charged.
No, the atom would have to be in an environment where it could gain or loose electrons.
Atoms will form an ionic bond when one atom donates an electron to another atom. Typically, this occurs between a metal atom (which tends to lose electrons to form positive ions) and a non-metal atom (which tends to gain electrons to form negative ions).
The number of electrons an atom gains or loses determines whether it forms a positive or negative charge in an ionic bond. Atoms that lose electrons become positively charged ions (cations), while atoms that gain electrons become negatively charged ions (anions).
Charged particles that form when atoms gain or lose electrons are called ions. When an atom gains electrons, it becomes a negatively charged ion (anion). When an atom loses electrons, it becomes a positively charged ion (cation).
Nonmetals typically form anions when they gain electrons during chemical reactions. This results in the formation of negatively charged 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.
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-.
A negatively charged ion forms when an atom gains one or more electrons. This causes an imbalance between the number of protons (positive charge) and electrons (negative charge), resulting in an overall negative charge on the ion.
This statement is incorrect. Cations form when an atom loses electrons, resulting in a net positive charge.
Electrons are the subatomic particles that are transferred to form ions. When an atom loses or gains electrons, it becomes an ion with a positive or negative charge.
When atoms lose or gain electrons and become positively or negatively charged, they form ions. Positively charged ions are called cations, while negatively charged ions are called anions.
