Calculate numbers of protons, neutrons, and electrons by using mathematical expressions (1-3): p = 11 (1) n = 23 - 11 = 12 (2) e = 11 - 0 = 11 (3) Alternatively, you can also calculate the atomic number, atomic mass, and charge. Choose your element. Let's assume that it is the sulfide anion. Find the numbers of protons, neutrons, and electrons.

You already know how to find the mass number of an isotope by adding the protons and neutrons. We can state the relationship between protons, neutrons, and mass number with the following equation: A = N + Z. atomic mass number = number of neutrons + atomic number (number of protons)

26 sie 2024 · Consider oxygen, which has an atomic number (\(Z\)) of 8. This means that oxygen atoms have 8 protons. Most atoms of oxygen also have 8 neutrons. Oxygen atoms with 8 neutrons would have a mass number of 16 (8 \(\mathrm p^+\) + 8 \(\mathrm n^0\)), meaning they would have a mass of about 16 amu.
The most important part you will need for calculating the number of neutrons is that together with protons, they make the atomic mass of the given isotope. So, if we have the mass number of the given isotope, we can easily determine the number of its neutrons.
1 wrz 2024 · For example, boron (B) has an atomic number of 5, therefore it has 5 protons. Determine the number of electrons. Protons are particles in the nucleus of an atom that have a positive charge equal to +1. Electrons are particles that have a negative charge equal to -1.
The phosphate/oxygen ratio, or P/O ratio, refers to the amount of ATP produced from the movement of two electrons through a defined electron transport chain, terminated by reduction of an oxygen atom.
