Question

use the periodic table to answer the following question. write the atomic symbol (including the atomic number and mass number) for phosphorus - 32. write the answer in the form $_z^a x$ using the atomic symbol button in the toolbar, where $a$ is the mass number, $z$ is the atomic number, and $x$ is the chemical symbol for the unknown element.

Explanation:

Step1: Find atomic number of phosphorus

From the periodic table, the atomic number ($Z$) of phosphorus is 15.

Step2: Identify mass number

The problem states it is phosphorus - 32, so the mass number ($A$) is 32.

Step3: Determine chemical symbol

The chemical symbol ($X$) for phosphorus is P.

Answer:

$_{15}^{32}\text{P}$
