What happens when chlorine forms an ion? It gains an electron and has an octet in its outer shell.

In ionic compounds, atoms gain or lose electrons to form ions. For example, table salt is made from the elements sodium and chlorine. When they get close enough, an electron transfers from the sodium to the chlorine. This makes a positive sodium ion, Na+, and a negative chloride ion, Cl-.

Sodium has 1 electron in its outermost shell, and chlorine has 7 electrons. It is easiest for sodium to lose its electron and form a +1 ion, and for chlorine to gain an electron, forming a -1 ion.

What happens when potassium forms an ion? It loses an electron and has an octet in the next-lowest energy level. The bond strength of compounds A, B, C, and D as measured by their bond energies (kJ/mol) are 350, 500, 180, and 1,450, respectively.

Chlorine gains an electron, leaving it with 17 protons and 18 electrons. Since it has 1 more electron than protons, chlorine has a charge of −1, making it a negative ion. When ions form, atoms gain or lose electrons until their outer energy level is full.

To find the ionic charge of an element you’ll need to consult your Periodic Table. On the Periodic Table metals (found on the left of the table) will be positive. Non-metals (found on the right) will be negative.

That means an atom with a neutral charge is one where the number of electrons is equal to the atomic number. Ions are atoms with extra electrons or missing electrons. When you are missing an electron or two, you have a positive charge. When you have an extra electron or two, you have a negative charge.

Key Points

1. The electronic configuration of many ions is that of the closest noble gas to them in the periodic table.
2. An anion is an ion that has gained one or more electrons, acquiring a negative charge.
3. A cation is an ion that has lost one or more electrons, gaining a positive charge.

Cations and Anions

Phosphate rock is processed to produce phosphorous, which is one of the three main nutrients most commonly used in fertilizers (the other two are nitrogen and potassium). Phosphate can also be turned into phosphoric acid, which is used in everything from food and cosmetics to animal feed and electronics.

Phosphate(3-) is a phosphate ion that is the conjugate base of hydrogenphosphate. It is a phosphate ion and a trivalent inorganic anion.

ion, respectively. These names are also used for salts of those anions, such as ammonium dihydrogen phosphate and trisodium phosphate….Phosphate.

Weak acids are only slightly ionized. Phosphoric acid is stronger than acetic acid and so is ionized to a greater extent. Acetic acid is stronger than carbonic acid, and so on….Strong and Weak Acids and Acid Ionization Constant.

Phosphate ion is a reasonably strong base. It hydrolyzes in water to form a basic solution.
