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.
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.
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.
Negative ions form when atoms GAIN valence electrons.
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).
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.
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).
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.
Non-metal atoms gain an electron, or electrons, from another atom to become negatively charged ions.
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-.
Cations are positive ions, so an atom is supposed to lose electrons to become a cation. Anions are formed when an atom gains electrons.
Ions are formed by the gain OR loss of an electron.
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.
When atoms lose or gain electrons, they form ions. These are charged particles.
