Which 2 parts in an atom have the same mass?
Protons and neutrons have approximately the same mass in an atom. Protons have a mass of about 1 atomic mass unit (amu), while neutrons have a slightly larger mass of about 1 amu.
Is the mass of a single electron one mass unit?
No, it's about 1/2000th of an amu (atomic mass unit). Protons and neutrons are 1 amu.
Which subatomic particle has a mass of 1amu?
Protons and neutrons have the mass of 1 amu.
What is the number of neutrons mass atomic protons electrons in tritium?
1 proton 1 electron 2 neutrons mass = 3 amu
What are the sizes of portons neutrons and electrons?
Protons and neutrons, which are found in the nucleus of an atom, have masses of approximately 1 atomic mass unit (amu), with protons having a mass of about 1.007 amu and neutrons about 1.008 amu. Electrons are significantly smaller, with a mass of about 0.0005 amu, or roughly 1/1836 of a proton's mass. In terms of size, protons and neutrons are roughly 1 femtometer (10^-15 meters) in diameter, while electrons are often considered point-like particles with no defined size.
Electrons have a mass of 1 amu?
1 atomic mass unit = 1.66053886 × 10-27 kilograms-Greg
Are neutrons neutal and do thay have a mass of 1amu?
Yes, they are neutral; and yes, their mass is close to 1 amu.
What sub-atomic particles have a mass of 1 amu?
neutrons and protonsbut NOT electrons (the almost have no mass)
How do you identify the relative mass relaitive charge and location of the three smaller subatomic particle 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.
What is the mass of an atom with 34 protons 34 electrons and 45 neutrons?
The mass of an atom is primarily determined by the sum of its protons and neutrons, as electrons contribute negligible mass. In this case, the atom has 34 protons and 45 neutrons, giving it a total nucleon count of 79. The atomic mass is approximately 79 atomic mass units (amu), assuming the mass of protons and neutrons are roughly 1 amu each. Thus, the mass of the atom is about 79 amu.
What is the mass defect of lithium-7 Assume the following Atomic number of lithium 3 Atomic mass of lithium 7.016003 atomic mass units. Mass of 1 proton 1.007276 atomic mass units. Mass of 1 neutron 1?
To calculate the mass defect of lithium-7, we use the formula: Mass defect = (mass of protons + mass of neutrons) - mass of lithium-7. Given that lithium-7 has 3 protons and 4 neutrons, the total mass of protons is 3 x 1.007276 = 3.021828 amu, and the total mass of neutrons is 4 x 1 = 4 amu. Therefore, the total mass of protons and neutrons is 3.021828 + 4 = 7.021828 amu. The mass defect is then 7.021828 - 7.016003 = 0.005825 amu.
An atom of tritium an isotope of hydrogen has 1 proton 2 neutrons and 1 electron What is its mass in amu?
The mass of tritium (T) can be calculated by adding the masses of its constituents. The mass of a proton is approximately 1.0073 amu, the mass of a neutron is approximately 1.0087 amu, and the mass of an electron is negligible. So, the mass of tritium would be approximately 3.016 amu.
