Question

phosphorous
symbol:
no. of electrons:
atomic number:
atomic mass:

Explanation:

Step1: Recall the symbol of phosphorus

The symbol for phosphorus is \( P \).

Step2: Determine the number of electrons

For a neutral atom, the number of electrons equals the atomic number. Phosphorus has an atomic number of \( 15 \), so the number of electrons is \( 15 \).

Step3: Identify the atomic number

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

Step4: Find the atomic mass

Looking at the periodic table, the atomic mass of phosphorus (rounded to the nearest whole number) is \( 31 \).

Answer:

Symbol: \( P \)
No. of Electrons: \( 15 \)
Atomic Number: \( 15 \)
Atomic Mass: \( 31 \)
