Web5 jun. 2024 · Ions are formed when atoms lose or gain electrons in order to fulfill the octet rule and have full outer valence electron shells. When they lose electrons, they become positively charged and are named cations. When they gain electrons, they are negatively charged and are named anions. Are formed by gaining or losing of electrons? Web19 sep. 2024 · Atoms that lose electrons acquire a positive charge as a result because they are left with fewer negatively charged electrons to balance the positive charges of the …

5.7: Ions - Losing and Gaining Electrons - Chemistry LibreTexts

WebIons are formed only through the loss or gain of electrons; there is no change in the number of protons in the nucleus of the atom (s). If electrons are lost, there are more protons than electrons in the resulting ion and so it has a positive charge. Web15 dec. 2024 · When forming ions, elements typically gain or lose the minimum number of electrons necessary to achieve a full octet. For example, fluorine has seven valence electrons, so it is most likely to gain one electron to form an ion with a 1- charge. We can use this method to predict the charges of ions in ionic compounds.
