Which statement compares the masses of two subatomic particles?
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).
What is water mass?
What is water mass?depends on the volume of water but one molecule should be about ahhh lets seemolecules are measured in Atomic Mass Units (amu)hydrogen is 1 amu and oxygen is 16 amu so..h20 =h * 1 amu * 2 molecules= 2o * 16 amu * 1 molecule = 162 + 16 = 18 amu or 18 grams/ mol
Which unit would be used to measure the size of an atom?
The mass of atoms is generally measured in amu (atomic mass units), where 1 amu = 1/12th the mass of an atom of carbon-12. The mass of subatomic particles may also be expressed in amu, or sometimes as the energy equivalent in eV (electron volts). Usually MeV or GeV are required to specify mass... an electron volt is a tiny amount of energy.
What is smaller in terms of size than an atom?
Subatomic particles are smaller than atoms. Subatomic particles are found inside the nucleus of an atom and include protons, neutrons, quarks, and gluons. Protons carry a positive electrical charge while neutrons carry a neutral charge. Inside these protons and neutrons are quarks which are held together by gluons. (1 atom = 0.000000001 meters while 1 quark = 0.000000000000000001 meters) The smallest known particle, however, that has mass is the neutrino.
How do you calculate relative formula mass?
An example of how to get formula mass is shown below with the example of water (H2O). H2O 2 H atoms x 1.01 amu/atom = 2.02 amu 1 O atom x 16.00 amu/atom = 16.00 amu 2.02 amu + 16.00 amu = 18.02 amu
What is the subatomic particles mass of 1amu?
The neutron and the proton have masses close to 1 amu.
Which subatomic particle has a mass of 1amu?
Protons and neutrons have the mass of 1 amu.
What is the subatomic particle that has the greatest mass?
The largest subatomic particle (by mass) is the proton. The mass of subatomic particles is measured in atomic mass units (amu). The proton has a mass of 1.007 amu, the neutron has a mass of 1 amu, and the electron has a mass of .0005 amu.
What is 1amu?
1 amu (atomic mass unit) is a unit of mass equal to one twelfth of the mass of a carbon-12 atom. It is used to express the mass of atomic and subatomic particles.
What are is the 3 subatomic particles and their masses?
The three particles are protons, neutrons, and electrons. the masses of protons and neutrons both approximately 1 amu (Atomic Mass Unit). The mass of an electron is, in most applications, negligible, but is about 1/1836 amu.
What two subatomic substances have a mass of about 1 amu?
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.)
Which subatomic particle has a charge of 1 and a mass of 1 AMU?
Both one proton and one neutron each has a relative mass of 1 a.m.u.
How do you identify the relative mass the relative charge and location of the three smaller subatomic particles of an atom?
protons --- rel. mass 1 amu, rel. charge +1, location in the nucleus. neutrons --- rel. mass 1 amu, rel. charge 0, location in the nucleus. electrons --- rel. mass 0 amu, rel. charge -1, location outside the nucleus.
The mass and charge of each subatomic particles and the nucleus?
Subatomic particles are measured in AMU.1 Proton = 1 AMU (Positive Charge [think pro])1 Neutron = 1 AMU (No Charge [think NEUtral])1 Electron = 1/1836 AMU (Negative Charge)
What are the Subatomic particles of the atom with their charges?
Neutron: Mass: 1,00866491600(43) amu. Charge: neutral James Chadwick, 1932 Electron: Mass: 5,4857990946(22)×10−4 amu. Charge: negative J. J. Thomson, 1897 Proton: Mass: 1,007276466812(90) amu. Charge: positive
The weight of subtomic particles is measured in units called atomic mass units true or false?
Yes, true: the mass of 1 proton is exactly the same as of 1 neutron: 1 a.m.u.
Mass of a subatomic particles?
For the particles in atom: Neutron: Mass: 1,00866491600(43) amu. Electron: Mass: 5,4857990946(22)×10−4 amu. Proton: Mass: 1,007276466812(90) amu.
