Question

How many electrons does a neutral atom of oxygen-18 have? 8 O 16.00

A. 8
B. 10
C. 18
D. 16

Answer 1

Answer:A

Explanation:The answer is a because a neutral atom of oxygen is represented as O. It is atomic number of 8. Hence, it contains 8 electrons and 8 protons.

Answer 2

A. 8

Step-by-step explanation:

Atomic number of oxygen = 8

Oxygen is the 8th element in periodic table.

Atomic no. = 8, means one oxygen atom has 8 protons. Now, because the atom is neutral, so number of electrons = no. of protons in an atom.

Hence, the number of electrons in a neutral oxygen atom is 8.
