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 GAIN valence electrons.
When atoms lose or gain electrons, they form ions. These are charged particles.
No. Atoms of an element lose or gain electrons to form ions.
Atoms gain electrons to form negatively charged anions. Atoms lose electrons to form positively charged cations.
they are ions
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.
Electrons always have their charge, when atoms gain electrons, they become ions.
ions are formed by the transfer of electrons. Cations are formed when atoms lose electrons, anions are formed when atoms gain electrons. Ionic bond is the electrostatic force of attraction between the oppositely charged ions.
No, the atom would have to be in an environment where it could gain or loose electrons.
They can do both to form ions. An ion simply means that there is an uneven distribution of charge, so it can be positive or negative.
Ions. Cations have lost electrons and have a positive charge. Anions have gained electrons and have a negative charge.
Metals have a low number of valence electrons, so it is favorable for metals to lose electrons to form positive metallic ions and gain a complete v.e. shell.
