if the atom loses one or more electrons, it becomes a positively-charged ion. if the atom gains one or more electrons, it becomes a negatively-charged ion. A helium atom has two electrons in an...
The strong electrostatic attraction between the positive metal ions and the sea of negative delocalised electrons hold the metal together. Covalent Bonding. A covalent bond is a chemical bond where electron pairs are shared between atoms.
When the electrons are transferred, it creates charged particles called ions . Oppositely charged ions attract through electrostatic forces to form a giant ionic lattice .

Revision notes on 1.1.6 Ionisation Energy for the AQA A Level Chemistry syllabus, written by the Chemistry experts at Save My Exams.
Ion, any atom or group of atoms that bears one or more positive or negative electrical charges. Positively charged ions are called cations; negatively charged ions, anions. Ions migrate under the influence of an electrical field and are the conductors of electric current in electrolytic cells.
