The difference in the mass of the Nitrogen-14 and Nitrogen-15 atom is because nitrogen-15 has 8 neutrons while nitrogen-14 has 7 neutrons.
<h3>What is atomic mass of an element?</h3>
Atomic mass of an element is the sum of the masses of the protons and neutrons in the nucleus of an atom.
<h3>Why is the atomic mass of Nitrogen-14 and Nitrogen-15 different?</h3>
The difference in the mass of the Nitrogen-14 and Nitrogen-15 atom is due to the difference in the number of neutrons.
Nitogen-15 has 8 neutrons while nitrogen-14 has 7 neutrons.
Therefore, the difference in the mass of the Nitrogen-14 and Nitrogen-15 atom is because nitrogen-15 has 8 neutrons while nitrogen-14 has 7 neutrons.

<h2>Answer : Option D) The He quarks</h2><h3>Explanation : </h3>
The scientist uses an accelerator and high energy electrons to study the particles inside the protons of a helium atom, the particles under study are quarks.
Quarks are the elementary and fundamental part of matter. In Helium nucleus when the high energy is bombarded to study the particles inside the proton it is obvious that the scientist is studying the quarks inside the proton. In a proton there are two up quarks and one down quark present.
Answer: [H3O+] > [OH-] and Kw = 1 x 10 -14
Explanation:
i just had this question and tried to look it up and i got it right by guessing my bad but i hope this is ur answer as well
An oxygen atom is always made up of 8 protons.
The mass number of an atom is made up of both protons and neutrons.
So to find out the number of neutrons, you subtract the number of protons from the mass number.
Number of neutrons = Mass number - number of protons
So for oxygen with a mass number of 18:
There are: 18 - 8 = 10 neutrons
------------------------------------------------
Answer:
There are 10 neutrons in an atom of oxygen with a mass number of 18.
