a negative ion... this was Ben McClanahan for you A+ people out there :))
They become ions. If they lose electron they become positive - cations, and if they gain it they become negative - anions.
A negative ion, otherwise known as an anion.
Atoms which loss electrons becomes cations, positively charged.
Atoms which gain electrons becomes anions, negatively charged.
because then it's balanced
to become stable
Cations form when atoms lose electrons, they gain a positive charge as a result.
An ion is an atom with a net electric charge. An ion is formed when an atom either gains or loses a valence electron. Atoms with an unfilled outer shell tend to gain or lose electrons so they can achieve a filled outer shell. Atoms that gain an electron are negative ions, and atoms that lose an electron are positive ions.
In the simplest sense, an atom can either gain or lose an electron to become more stable. Very electronegative atoms like fluorine and oxygen tend to gain electrons, whereas atoms that are less electronegative like the alkali metals tend to lose electrons. In these cases, an electron is sent to a lower energy state, thus making the atom more stable.
Nitrogen atoms gain 3 electrons and form the nitride ion, N3-. Nitrogen atoms also form covalent bonds where they share 3 electrons and do not become ions. Bromine atoms gain 1 electron and form the bromide ion, Br-. Bromine atoms also form covalent bonds when they share 1 electron and do not become ions.
A stable electron configuration.
1. Gain an electron. 2. Lose an electron.
For example metals loss electrons and nonmetals gain electrons.
Lose or gain an electron
In a nitrogen atom's ground state, it has five atoms. The electron will have to gain three electrons to become stable.
The non-metallic atoms will gain electrons, while the metallic atoms will lose electrons to become ions. An ionic compound is thus formed and all ions will have the noble gas configuration/structure.
because then it's balanced
When ions are formed atoms can lose or gain electrons. If they lose and electron they become positively charged. This is typical for [although not exclusive to] metals in chemical reactions. If they gain an electron the become negatively charged. This is typical for [although not exclusive to] non-metals in chemical reactions. Electrons can also be knocked out of an atom by radiation. Again the atom would be come positively charged under these circumstances.
The atom needs to gain an electron so it has more than the protons Hope I helped
to become stable
Gain of an electron transform the atom in an anion.Loss of an electron transform the atom in a cation.
