(03 Marks)
An atom has a neutral charge and an equal number of protons and electrons. Electrons
arrange themselves in layers or rings called “shells.” One shell holds up to 8 electrons.
An atom can have many shells, depending on how many electrons it has. Shells always
fill up all the way to 8 before adding a new shell. The outermost shell may have fewer
than 8 electrons. The electrons in the outermost shell are known as valence electrons.
Sometimes (such as during bonding), these valence electrons jump and attach to
another atom. If an atom gains or losses electrons, its charge changes and it does not
remain neutral. The atom is then known as an ion.
If an atom loses electrons, its charge becomes positive and it’s called a cation.
If an atom gains electron, its charge becomes negative and it’s called an anion.
