The atomic number of an isotope is the number of protons it contains, whereas the mass number is the total mass of the nucleus, which is the combined number of protons and neutrons in the nucleus. To find the number of neutrons, you must therefore subtract the atomic number of the isotope from the mass number of the isotope.
<span>In the above example, the atomic number is 8 and the mass number is 18. This isotope is known as O18. The number of neutrons in the isotope is: Mass number - Atomic number = Number of neutrons

Damage to heart valves can lead to heart murmur.
Explanation:
Heart murmur refers to the sound of blood flow. The sound of flowing blood in the heart is usually not heard.
The heart murmurs can result due to two reasons that is either a damaged valve or any condition that causes the heart to beat at a faster rate.
The types of damage to the heart valve that may lead to heart murmurs are:
Mitral valve prolapse, Mitral valve or aortic stenosis and Mitral or aortic sclerosis.
Sometimes, the murmurs do not signify a serious condition but under certain condition they may indicate the risk of heart failure.
The advantage to a scientist is that it makes calculations easy using exponential functions. The disadvantage is that it may not capture some subtle complication that changes the answer at the fifth place after the decimal point.<span>
