Cations donate electrons from their valance shell, have less, to reach their octet state.
Anions accept electrons into their valance shell, have more, to reach their octet state.
Actually all the ions will have. Al3+, O2- and N3- ions will have the same number of electrons as neon (10 electrons), whereas Br- ion will have the same number of electrons as krypton (36 electrons)
Ions that are deficient in electrons are called cations. Cations have a positive charge due to the lack of electrons compared to the number of protons in the nucleus. These ions are typically formed by metals losing electrons during chemical reactions.
The number of electrons does not equal the number of protons.
This is not a general valid rule; ions have a different number of electrons.
Ions always have an unequal number of protons and electrons, resulting in a net electric charge. This charge can be positive if there are more protons than electrons, or negative if there are more electrons than protons. The number of neutrons in an ion can vary.
Ions have electronic charge. As ions are molecules or atoms with a different number of electrons(-1) to protons(+1) a positive ion has less electrons, and a negative ion has more
Ions are changed atoms of elements that have an unequal number of protons and electrons. This imbalance gives the ion a net electric charge, either positive (if there are more protons) or negative (if there are more electrons).
Ions.
Ions form when electrons are transferred between atoms, resulting in a difference in the number of protons and electrons. This creates ions with either a positive charge (cation) or a negative charge (anion) based on the imbalance of electrons.
To maintain the neutrality of an atom the number of neutrons must be equal to number of electrons; in ions this number is not equal.
Ions are formed when an atom gains or loses electrons and gets charged. If an atom gains electrons, number of electrons exceed from the number of proton and hence an atom gets negatively charged. Similarly if an atom looses electrons the total number of protons become more than the number of electrons.. and the atom becomes positively charged.
In stable atoms, number of protons = number of electrons. In positively-charged ions, number of protons = number of electrons + charge of the ion. In negatively-charged ions, number of protons = number of electrons - charge of the ion. Hope this helped! NO THATS A COMPLETE LIE. all you have to do is split the atom and look inside of it.
