Valence electrons - Coggle Diagram
Valence electrons
Anion formation
An anion is a negatively charged ion. They can easily gain electrons to obtain a stable outside ring of electrons.
Naming Anions
If you take away the end of an ion and add -ide to the end, this means that it is a negative charge.
Cation Formation
Cations form when an atom loses one or more valence electrons in order to obtain noble gas configuration.
Crystal
A crystal is highly ordered. All of the atoms are put together into one crystal. For example, it could be a sodium chloride crystal. Since positives and negatives attract, they are all ordered in a way where no positives and negatives are touching.
Crystal Lattice
It is a three-dimensional geometric arrangement of particles. Each positive ion is touching a negative ion and vice versa. No positives are touching and no negatives are touching.
Lattice energy
because the ions in an ionic compound are arranged in a crystal lattice, the energy required to separate 1 mol of the ions of an ionic compound is referred to as the lattice energy. Lattice energy is directly related to the size of the ions bonded.

are defined as electrons in the atom’s outermost orbitals. Generally, those orbitals are associated with the atom’s highest principal energy level. Also, valence electrons recall than electron-dot structure is a type of diagram used to keep track of valence electrons.
