Calculate the number of neutrons of the atom whose atomic number is 42 and whose mass number is 96?
To find the number of neutrons, subtract the atomic number (number of protons) from the mass number. For this atom with an atomic number of 42 and a mass number of 96, the number of neutrons would be 96 - 42 = 54 neutrons.
Is the mass number equal to the number of protons and electrons?
No, it isn't. The mass of an electron is significantly smaller than that of a proton.The mass of 1,800 electrons is about the same as the mass of one single proton.The antiparticle of the electron, the positron, has the same mass as the electron.the mass of the electron is not the same to the mass of the proton
What particle has the lowest mass number?
The particle with the lowest mass number is the electron, which has a mass number of 0. This is because electrons are considered to be fundamental particles and do not consist of smaller subatomic particles like protons and neutrons.
An atom of carbon whose mass number is 14 differs from an atom of carbon whose mass number is 12 in that it has?
neutrons, subtract the atomic number from the mass number to find the number of neutrons, atomic number is the number is the amount of protons, atomic mass is the average mass of one mole of atoms. each particle wieghing one amu (atomic mass unit)
Who has the smallest mass electrons protons or neutrons?
Of the neutron, proton, and electron, the electron has the smallest mass.
Calculate the number of neutrons of the atom whose atomic number is 42 and whose mass number is 96?
To find the number of neutrons, subtract the atomic number (number of protons) from the mass number. For this atom with an atomic number of 42 and a mass number of 96, the number of neutrons would be 96 - 42 = 54 neutrons.
Why is mass number calculated with only the protons and neutrons and not electrons?
Because the mass of electron is negligible when compared to the mass of protons or neutrons.
Calculate the number of protons of the atom whose mass number is 19 and whose number of neutrons is 10?
To find the number of protons, you need to subtract the number of neutrons from the mass number. In this case, the atom has a mass number of 19 and 10 neutrons, which means the number of protons is 19 - 10 = 9 protons.
What is the number of neutrons mass atomic protons electrons in tritium?
1 proton 1 electron 2 neutrons mass = 3 amu
Why is the mass of an atoms electrons not included in the atoms mass number?
Mass number is defined as the number of protons and neutrons. It is related to Atomic Mass which incudes electron mass and nuclear binding energy , (binding energy reduces the overall mass relative to the combined masses of the protons and neutrons.) Electron mass is not included as mass number is element specific wheras the count of electrons varies depending on the chemical state. The mass of electrons is negligible compared to the mass of the protons and neutrons, binding energy is a larger effect.
What is hydrogen's number of neutrons equals mass number - atomic number equals?
The number of neutrons in an atom can be calculated by subtracting the atomic number (number of protons) from the mass number. For hydrogen, the atomic number is 1 and the mass number is also 1. Therefore, the number of neutrons in hydrogen is 1 (mass number - atomic number = 1 - 1 = 0 neutrons).
The electron has very little mass compared to the blank or blank fill in the blank please Number Standard Neutrons Protons Mass?
The electron has very little mass compared to the proton or neutron.

The particle with the lowest mass number is the electron, which has a mass number of 0. This is because electrons are considered to be fundamental particles and do not consist of smaller subatomic particles like protons and neutrons.
The number of neutrons in an atom can be found by subtracting the atomic number from the?
Atomic weight in atomic mass units = the number of protons + the number of neutrons. The number of protons is your atomic number. Subtract that from the atomic weight for the number of neutrons.
Why is the atomic mass generally used to refer to just the number of protons and neutrons?
The weight of an electron is negligible compared to that of protons and neutrons.
