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 symbol

The symbol of oxygen is O.

Step2: Determine atomic number

The atomic number (top - left number) of oxygen is 8.

Step3: Determine atomic mass

The atomic mass (bottom number) is 15.999.

Step4: Find number of protons

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

Step5: Calculate number of neutrons

Neutrons = Atomic mass (rounded) - Protons. Rounding 15.999 to 16, Neutrons = 16 - 8 = 8.

Step6: Determine number of electrons

For a neutral atom, the number of electrons is equal to the number of protons, so it is 8.

Answer:

ATOMIC #: 8
ATOMIC MASS: 15.999

OF PROTONS: 8

OF NEUTRONS: 8

OF ELECTRONS: 8
