Question

7 identify the element based on the information below: it is a gas, has an atomic mass of 16 and 8 neutrons

Explanation:

Step1: Calculate number of protons

Atomic mass = Protons + Neutrons. Given atomic mass = 16 and neutrons = 8. So, Protons = Atomic mass - Neutrons = 16 - 8 = 8.

Step2: Identify the element

The number of protons is equal to the atomic number. An element with atomic number 8 is oxygen.

Answer:

Oxygen
