Ahh the charges! I know just how to help!!
One thing I do is I draw each individual proton or electron out. Make sure you label each proton with a + and each electron with a -.
Then I cross them out. For each proton you cross out, cross out an electron and vice-versa.
If you end with a proton, then the atom is positive.
If you end with an electron, then the atom is negative.
If you end with nothing, then it is neutral.
HOPE THIS HELPS!!!!!! Let me know if you have more questions!!
The atomic mass can be defined as the mass of neutrons and protons in the atom. The atomic mass of the oxygen isotope is 18 amu.
<h3>What is an atom?</h3>
An atom is the smallest particle comprised of three subatomic units, namely electrons, protons, and neutrons.
The number of electrons in the atoms determines the atomic number, while the number of protons and neutrons determines the atomic mass.
The atomic mass can be given as:
The oxygen isotope has been comprised of 10 neutrons and 8 protons. The atomic mass of the isotope is given as:
The atomic mass of the oxygen isotope is 18 amu. Thus, option C is correct.

Stratigraphy is a branch of geology which studies rock layers (strata) and layering (stratification). It is primarily used in the study of sedimentary and layered volcanic rocks. Stratigraphy has two related subfields: lithologic stratigraphy or lithostratigraphy, and biologic stratigraphy or biostratigraphy.
