Question

question 4 (1 point) given the following elemental symbol, how many protons and neutrons does the element have? oxygen 15.999 a 8 protons, 10 atoms b 8 electrons, 8 protons c 8 protons, 8 neutrons d 8 protons, 8 electrons

Explanation:

Step1: Identify atomic number

The atomic number of oxygen is 8. The atomic number is equal to the number of protons. So, the number of protons in oxygen is 8.

Step2: Identify mass - number and calculate neutrons

The mass - number (top right number) is 16. Mass number = number of protons+number of neutrons. So, number of neutrons = mass number - number of protons = 16 - 8=8.

Answer:

C. 8 protons, 8 neutrons
