Explanation:
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.

They are converted into a single “o” when "ao" or "oo" are together when naming covalent bonds.
<h3>What is a covalent bond?</h3>
A covalent bond consists of the mutual sharing of one or more pairs of electrons between two atoms.
Sometimes, while naming the chemical compounds, a problem arises when compounds with “ao” and “oo” are written with -ide name. Conventionally, they are converted into a single “o”.
For example, the “ao” in the dichlorine hept-ao-xide (
). This “ao” in the
can be converted into “o”. As the result, the correct name of this compound would be dichlorine hept-o-xide.
Hence, they are converted into a single “o” when "ao" or "oo" are together when naming covalent bonds.
