<h2>
Answer: # of neutrons = 9</h2>
<h3>
Explanation:</h3>
# of neutrons = mass number - atomic number
= 17 - 8
= 9
<h3>∴ number of neutrons in an atom of oxygen of mass number 17, is 9.</h3>
The mass of electrons , i just did the same test and got it right
Answer:
His third law states that for every action (force) in nature there is an equal and opposite reaction. In other words, if object A exerts a force on object B, then object B also exerts an equal and opposite force on object A. Notice that the forces are exerted on different objects.
Explanation:
Answer:
14
Explanation:
there are 14 electrons in the shells
9/1 ratio so 9:1=36:x
X is your hydrogen in the 36g sample. To find the mass of Oxygen you subtract the mass of hydrogen from the total.
4 grams H
36-4=32 g h2o
