A.
The atomic number is 16 and the atomic mass is 8.
B.
The atomic number is 8 and the atomic mass is 8.
C.
The atomic number is 8 and the atomic mass is 16.
D.
The atomic number is 16 and the atomic mass is 4.
E.
The atomic number is 4 and the atomic mass is 16.

Answer 1

Answer:

Atomic no. 8 and atomic mass 16

Answer 2

Answer:

C

Explanation:

Atomic Number= Number of Protons

Thus, Atomic Number=8

Atomic Mass= Number of protons + Number of Neutrons

Thus, Atomic Mass =8+8

                               = 16u

Therefore, correct option is (c)
