Transition metals (elements between groups 2 and 13) are able to have varied charges that there is no real rule for.
Chlorine typically has a charge of -1 as an ion.
If an ion has more electrons than protons, it would have a negative charge. The charge of the ion would be equal to the excess of electrons over protons.
The charge on the potassium ion is +1, as it is a Group 1 element. The charge on the bromide ion is -1, as it gains one electron to achieve a full octet in its outer shell.
Aluminum (Al) is in group 3A and so has 3 valence electrons. It can easily lose these to become Al^3+, so the charge would be +3.
The ion would have a positive charge equal to the difference between the number of protons and electrons. For example, if there are 10 protons and 8 electrons, the ion would be a 2+ charged ion.
You would need one group 17 ion (e.g. a chloride ion) to balance the charge on one sodium ion, as sodium has a charge of +1 and group 17 ions have a charge of -1.
by subtracting 8 from the group number. this was answer by a Sone.
An ion is an atom (or group of atoms) with an electrical charge.
An iodine ion is named based on its charge. If it has a -1 charge, it is called an iodide ion. If it has a +1 charge, it is called an iodine ion.
Barium is in group two of the periodic table. Based on the information known for group one, it can be predicted (correctly) that barium will lose two electrons to form an ion with a plus 2 charge. Thus, the resulting ion in reactions of barium is Ba2+.
Chlorine typically has a charge of -1 as an ion.
If an ion has more electrons than protons, it would have a negative charge. The charge of the ion would be equal to the excess of electrons over protons.
The charge on the potassium ion is +1, as it is a Group 1 element. The charge on the bromide ion is -1, as it gains one electron to achieve a full octet in its outer shell.
The common ion charge of an element, Z, can be determined by looking at its position on the periodic table and its group number. Elements in the same group tend to have the same common ion charge due to their similar electron configurations. You can also refer to a periodic table to determine the common ion charge of element Z.
Aluminum (Al) is in group 3A and so has 3 valence electrons. It can easily lose these to become Al^3+, so the charge would be +3.
An ion is a particle that carries a charge, either positive or negative, due to losing or gaining electrons. It can be a single atom or a group of atoms that have an overall charge. A molecule is a group of atoms held together by chemical bonds and may or may not carry a charge.
The sulfate ion is SO42-. Elements in group 16 form anions with a charge of 2-, for example oxygen forms the oxide, O2- anion.
