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.
How is atomic mass number calculated?
There are a few ways to determine the mass number, depending on what information you have about the isotope: 1. The mass number is calculated as the sum of an isotope's protons and neutrons. 2. The name of an isotope generally includes the mass number. For instance, carbon-14 has a mass number of 14. 3. The atomic mass (aka isotope mass or atomic weight) rounded to the nearest whole number is the mass number.
How many protons and neutrons in the fluorine?
Fluorine has an atomic number of 9. Therefore it has 9 protons and electrons. It has an atomic mass of 19 amu. Therefore, the number of neutrons present can be calculated by subtracting the number of protons from its mass, i.e., 19-9=10. thus, fluorine has 9 protons and 10 electrons.
An atom has 13 protons and an atomic mass of 27 How many neutrons does this atom have?
The atom in question has 13 protons, so is atomic number 13, which is Aluminium. Assuming that all of the atom's mass is formed from the protons and neutrons, and each of these have atomic mass 1, the number of neutrons is 27 - 13 = 14 neutrons. Almost all Aluminium is of this isotope.
How can the number of proton neutron and electron be calculated to get atomic number and atomic mass?
atomic number is the amount of protons, equal to the atomic number, the electrons, minus the mass number atomic number is the amount of protons, equal to the atomic number, the electrons, minus the mass number atomic number is the amount of protons, equal to the atomic number, the electrons, minus the mass number
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.
How is the number of of neutrons in the nucleus of an atom calculated?
Subtract the number of protons from the mass number.
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.
What determines the atomicity of the elements?
The Atomic Mass number tells the atomic mass of an element. The mass is calculated as the mass of all the protons and neutrons in the center of an atom.
How is atomic mass number calculated?
There are a few ways to determine the mass number, depending on what information you have about the isotope: 1. The mass number is calculated as the sum of an isotope's protons and neutrons. 2. The name of an isotope generally includes the mass number. For instance, carbon-14 has a mass number of 14. 3. The atomic mass (aka isotope mass or atomic weight) rounded to the nearest whole number is the mass number.
What is equal to the total number of protons and neutrons?
If you add the number of protons to the number of neutrons in an atom, you have calculated that atom's atomic mass.
How do you find the mass number on the periodic table for the elements are calculated?
The mass number is the number of protons plus the number of neutrons in the atomic nucleus.
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.
How many protons and neutrons in the fluorine?
Fluorine has an atomic number of 9. Therefore it has 9 protons and electrons. It has an atomic mass of 19 amu. Therefore, the number of neutrons present can be calculated by subtracting the number of protons from its mass, i.e., 19-9=10. thus, fluorine has 9 protons and 10 electrons.
An atom has 13 protons and an atomic mass of 27 How many neutrons does this atom have?
The atom in question has 13 protons, so is atomic number 13, which is Aluminium. Assuming that all of the atom's mass is formed from the protons and neutrons, and each of these have atomic mass 1, the number of neutrons is 27 - 13 = 14 neutrons. Almost all Aluminium is of this isotope.
