ions. : if the atom loses one or more electrons, it becomes a positively-charged ion. if the atom gains one or more electrons, it becomes a negatively-charged ion. A helium atom has two...
An ionic compound is made up of charged particles, called ions. It has a giant lattice structure with strong electrostatic forces of attraction. Part of Combined Science Bonding, structure and...

Ionic compounds - Edexcel. When a metal element reacts with a non-metal element an ionic compound is formed. They have a giant lattice structure with strong ionic bonds. A lot of energy is...
To find the formula of an ionic compound, first identify the cation and write down its symbol and charge. Then, identify the anion and write down its symbol and charge. Finally, combine the two ions to form an electrically neutral compound.

- The overall structure needs to be neutral in terms of charge. Thus Ca has a charge of +2 and Br has a charge of -1. Therefore, to get a neutral com...
- Parentheses are generally only used for complex ions. Since the anion here, Br, is a single atom, there is no need to include parentheses. If the a...
- -ide is just the negative anion of that element, chloride, sulfide, nitride -ate depends on the central atom, it's generally the most common n eg p...
- It wants to fill its outer shell, and if it can do that easily by gaining an electron, that's what it will do.
- You would need to know what oxidation state the metal is in first. It should always be included in the name. Iron(II) bromide would be FeBr2 while...
- For the most part it depends on the group (column) in which the element is found in on the periodic table. It corresponds to how many valence elect...
- Halides are chemical compounds that contain halogens, so this example, CaBr2, is a Halide. Bromine itself is a Halogen.
- Ionic compound’s empirical formulae always have a neutral net charge, or a total charge of 0. The positive charges must equal and cancel all the ne...
- Calcium commonly forms a cation with a charge of +2 Bromine commonly forms an anion with a charge of -1 In the formula of an ionic compound we are...
Valence electrons and ionic compounds. 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.
