Verified step by step guidance

Identify the element and its position in the periodic table. Phosphorus (P) is in group 15, which means it has 5 valence electrons.

Understand the charge of the ion. The P3– ion indicates that phosphorus has gained 3 additional electrons, resulting in a total of 8 valence electrons.

Draw the electron-dot symbol for phosphorus. Start by placing the symbol 'P' in the center.

Distribute the 8 valence electrons around the phosphorus symbol. Place one pair of electrons on each side of the 'P' symbol, ensuring that all sides have a pair of electrons, representing a full octet.

Enclose the electron-dot structure in brackets and indicate the charge of the ion as 3– outside the brackets to show that it is an anion with three extra electrons.
