The proton an neutron both have a mass of about 1 amu.
(Both have a mass just slightly above 1 amu, and the neutron's mass is slightly larger than that of a proton.)
Hey, it's Song_Writer_Girl13 here! Protons have a +1 (postive) charge and a mass of 1 Neutrons have no electric charge and have a mass of 1 Electrions have a -1 (negative) charge and have a mass of about 0 (there actual mass is so small we just say it's about 0) Therefore, electrons have the greatest mass of the three subatomic particles. Hope I helped!
The two subatomic particles you add together to get the mass number of an atom are protons and neutrons. Protons have a positive charge, while neutrons have no charge, but together they contribute to the mass of an atom.
The neutron has a mass that is nearly equal to the combined mass of a proton and an electron. This is due to the fact that the neutron is slightly heavier than the proton, while the electron has a much smaller mass.
First of all, there's no such thing as the mass of a substance, or the volume of a substance. You can have 0.01 kilogram of water or 10,000 kilograms of water. It only depends on how much you decide to scoop out of the bucket. The water itself has no characteristic mass. Similarly, you can have 1 milliliter or 1 cubic kilometer of potato salad. It only depends on how much you buy at the deli. The potato salad itself has no characteristic volume. If you measure out the same mass of two different substances, then the sample of the substance with the greater density will have less volume. If you measure out the same volume of two different substances, then the sample of the substance with the greater density will have more mass.
Protons and neutrons have about the same mass, with slightly different values due to the binding energy in atomic nuclei. The mass of a proton is approximately 1.67 x 10^-27 kg, and the mass of a neutron is also approximately 1.67 x 10^-27 kg.
6 subatomic particles. 2 protons and 2 neutrons (that accounts for the mass of 4 amu) as well as 2 electrons.
Protons and neutrons. The amu of an atom is the total number of protons and neutrons added together.
The molar mass of potassium chloride is 74,5513.
Matter
Tritium has two neutrons and one proton: the mass is 3 amu.
Subatomic particles are measured in amu's--atomic mass units. Protons and neutrons are both approximately 1 amu, and electrons have a mass so much less as to be negligible (about 1/2000 that of a proton).
These particles are: proton and neutron.
Boron is the element that has two isotopes with atomic masses of approximately 10 amu and 11 amu. The most common isotope of Boron is Boron-11, which has an atomic mass of 11 amu, while the less common isotope Boron-10 has an atomic mass of 10 amu.
Sulfur is a non-metal with an atomic mass of 32 amu
The atomic mass of the element cannot be discovered with the given information. It was not specified as to the ratio of the isotopes of the element. If they two isotopes are equally represented, then it's half the sum of the masses of the two isotopes, which is 63 + 65 = 128, and 128 / 2 = 64 amu.If another ratio (or perhaps a percentage) of the isotopes if given, then a calculation can be made to discover the atomic mass of the element. This calculation will reflect the different amounts of the two isotopes present in samples of that element.Added:Though the answer given here is correct for the question stated above, there is a more clearing answer for the suggested question: Which element has two isotopes .... (etc.). This is typically true for copper, Cu, atom no. 29, of which two natural occurring isotopes exist:Cu-63, mass 62.92960 a.m.u., occurrence 69.1%Cu-65, mass 64.92779 a.m.u., occurrence 30.9%The average (relative) atomic mass = 63.55
In the atom, protons and neutrons; the mass of the electron is very small.
Neutrons and Protons.
