Atoms that gain electrons are called anions, and atoms that loose electrons are called cations
When an Neutral atom gains an electron its polarization changes and the neutral atom changes into Anion Which will atract positive Kations.
Atoms gain or lose electrons to get stable. Negative ions are made when electrons are gained. Positive ions are made when electrons are removed.
Since electrons are negative, they get a negative charge.
metals
an ionic bond forms
Metals lose electrons, nonmetals gain electrons.
Valence electrons-electrons that are farthest from an atoms nucleus- are the electrons that form bonds with other atoms.
Since electrons are negative, they get a negative charge.
nonmetals
metals
ions. (atoms that have lost or gained electrons)
Uranium loose electrons becoming a cation.
Atoms react to gain more stability and each element tend to obey octet rule. One atom react with other atoms and form different type of bonds either by complete transfer of electrons or by sharing of electrons, thereby trying to gain more stability by obeying octet rule.
an ionic bond forms
Atoms NEVER lose protons, just electrons.
Covalent bond
Electrons are transferred between atoms.
Electrons are smaller than atoms. There are electrons in atoms, but no atoms in electrons.
Non-metals gain electrons.
