B atoms
C protons
D electrons


Sagot :

Answer:

The correct answer is explained below:

Explanation:

The chemical formula of water is - H2O where two atoms of hydrogen and one atom of oxygen are there.

A. Neutrons - hydrogen has no neutron (assume all H are protonium)  and oxygen have 8 neutrons

B. Atoms - Hydrogen - 2 oxygen - 1

C. Protons - hydrogen has 1 proton each and a total of 2 as two atoms are present, oxygen has 8 protons

D. electrons- hydrogen 1 and oxygen has 8 electrons.

Therefore, the water molecule has:

Oxygen+ hydrogen = total

8 + 1 + 1 = 10 protons

8 + 0 + 0 = 8 neutrons

8 + 1 + 1 = 10 electrons.
