Question

5 fill in the blank 1 point 8 o type your answer... 15.999 atomic #: type your answer... atomic mass: type your answer... # of protons: type your answer... # of neutrons: type your answer... # of electrons: type your answer...

Explanation:

Step1: Identify element

The element is oxygen (O) with atomic number 8.

Step2: Determine number of protons

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

Step3: Determine number of electrons

In a neutral atom, the number of electrons is equal to the number of protons. So, the number of electrons is 8.

Step4: Calculate number of neutrons

The atomic mass is approximately 16 (rounded from 15.999). The number of neutrons = atomic mass - number of protons. So, number of neutrons = 16 - 8=8.

Step5: Fill in atomic number

The atomic number is 8.

Step6: Fill in atomic mass

The atomic mass is 15.999.

Answer:

ATOMIC #: 8
ATOMIC MASS: 15.999

OF PROTONS: 8

OF NEUTRONS: 8

OF ELECTRONS: 8
