They are calculated by Atomic Mass units (amu) proton-1amu neutron-1amu electron-0amu
What else can I help you with?
Protons are the same as the mass or the atomic?
The atomic number is the number of protons. For example, the atomic number of Hydrogen is 1, because it has 1 proton. The mass is calculated using protons, neutrons, and electrons.
An atom has 11 protons and 12 neutrons Its atomic mass is?
The atomic mass of an atom with 11 protons and 12 neutrons is calculated by adding the number of protons and neutrons together. In this case, the atomic mass would be 11 (protons) + 12 (neutrons) = 23 atomic mass units.
Which of the following particles is used to determine the mass of an atom?
Mass of an atom is determined by the no. of protons+ no. of neutrons in the atom.
A certain atom has 27 protons 27 electrons and 33 neutrons Its mass number is?
The mass number is calculated by adding the number of protons and neutrons together. In this case, the mass number would be 60 (27 protons + 33 neutrons).
What is the atomic mass of a number that have 8 protons and 9 neutrons?
The atomic mass of an atom can be calculated by adding the number of protons and neutrons together. In this case, an atom with 8 protons and 9 neutrons would have an atomic mass of 17 atomic mass units (amu).
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.
How do you find the mass of an element?
Mass number..can be calculated..by the sum of No. of protons and the No. of electrons. And this would give you the the mass number of the element.
Protons are the same as the mass or the atomic?
The atomic number is the number of protons. For example, the atomic number of Hydrogen is 1, because it has 1 proton. The mass is calculated using protons, neutrons, and electrons.
An atom has 11 protons and 12 neutrons Its atomic mass is?
The atomic mass of an atom with 11 protons and 12 neutrons is calculated by adding the number of protons and neutrons together. In this case, the atomic mass would be 11 (protons) + 12 (neutrons) = 23 atomic mass units.
The mass of a proton is 1.00727252 you The mass of a neutron is 1.008665 you What is the difference in the calculated and rest mass of an atom of lithium?
The rest mass of a lithium atom can be calculated by adding up the masses of its protons and neutrons. Lithium has 3 protons and 4 neutrons, so the calculated mass would be (31.00727252 + 41.008665 = 7.01600472 u). The rest mass of a lithium atom is approximately 7.016 u, so the difference between the calculated and rest mass is essentially zero.
How is the number of of neutrons in the nucleus of an atom calculated?
Subtract the number of protons from the mass number.
What is the mass number of ammonia?
The mass number of ammonia is 17. This is calculated by adding the number of protons and neutrons in the nucleus, which for ammonia (NH3) is 7 protons and 10 neutrons.
How can the number of protons electrons and neutrons be calculated when giving the mass number?
The atomic number must be known along with the mass number. Then the number of protons or electrons is the same as the atomic number, and the number of neutrons is the difference between the mass number and the atomic number.
Which of the following particles is used to determine the mass of an atom?
Mass of an atom is determined by the no. of protons+ no. of neutrons in the atom.
What mass number is calculated by adding the numbers?
the mass number of an atom is the number of protons in an atom, plus the number of neutrons.
A certain atom has 27 protons 27 electrons and 33 neutrons Its mass number is?
The mass number is calculated by adding the number of protons and neutrons together. In this case, the mass number would be 60 (27 protons + 33 neutrons).
What is the atomic mass of a number that have 8 protons and 9 neutrons?
The atomic mass of an atom can be calculated by adding the number of protons and neutrons together. In this case, an atom with 8 protons and 9 neutrons would have an atomic mass of 17 atomic mass units (amu).
