it loses a proton or gains an electron
Oxygen becomes a negatively charged ion, specifically the oxide ion, when it combines with a metal. The oxide ion has a charge of -2.
When an atom gains an electron, it becomes negatively charged and forms an anion. This process is known as reduction, and it can change the chemical properties of the atom by affecting its reactivity and ability to form bonds.
generally negatively charged chloride ion. but there are a few species where chlorine has positive charge like ClO3-, ClO4- etc.
Electrically Charged or Negatively charged
A negative charge attracts a positive charge and repels a negative charge. OPPOSITES ATTRACT ;)
When an element becomes an ion, it can either gain or lose electrons. If it loses electrons, it becomes a positively charged ion (cation). If it gains electrons, it becomes a negatively charged ion (anion). The charge of an ion is determined by the number of electrons it has gained or lost.
anion
A negatively charged ion.
If the atom was neutral, it becomes an anion. Since electrons have a (-) charge
electric charge
For a neutral atom to become an ion with a 2 plus charge it must LOSE TWO ELECTRONS.
A neutron. Negatively charged ion?
