The symbol An doesn't exist.
A carbon atom with the symbol 12C has 6 electrons since the atomic number of carbon is 6, indicating the number of protons and electrons in a neutral atom are the same.

The are none.
Magnesium, an alkaline earth metal, has two valance electrons. The symbol of magnesium is, Mg ----
8 electrons are found in each neutral
A sodium ion with the symbol Na+ has 10 electrons. Sodium normally has 11 electrons, but when it loses one electron to form a Na+ ion, it has 10 electrons.
There are three unpaired electrons in the Lewis symbol for a Phosphorous atom, represented by three dots surrounding the atomic symbol P. This indicates that Phosphorous has three unpaired electrons in its outer shell.

The symbol "symbol" seems to be a placeholder and does not correspond to a specific element in the periodic table. Each element has a unique number of electrons that is equal to its atomic number. For example, hydrogen has 1 electron, while carbon has 6. If you provide a specific element symbol, I can give you the exact number of electrons.
A cation is a positively charged ion, meaning it has lost electrons. In the case of a 1+ charge on a carbon cation, it would have 5 electrons (neutral Carbon has 6 electrons).
