If the atomic mass of an atom is 48 and the atom contains 20 protons how many neutrons does the atom contain?
If the atomic mass of the atom is 48 and it contains 20 protons, then the atom contains 28 neutrons. This can be calculated by subtracting the number of protons from the atomic mass, since the atomic mass includes both protons and neutrons.
Which part of the atom does the atomic mass measure?
The Nucleus contains Protons and Neutrons which comprise practically all the atom's mass.
What is the atomic mass of and atom?
the mass of an atom of a chemical element expressed in atomic mass units. It is approximately equivalent to the number of protons and neutrons in the atom (the mass number) or to the average number allowing for the relative abundances of different isotopes.
What is the atomic mass number of an sodium that contains 12 neutrons?
The atomic mass number of an atom is the sum of its protons and neutrons. Sodium (Na) has an atomic number of 11, meaning it has 11 protons. If it contains 12 neutrons, its atomic mass number would be 11 protons + 12 neutrons = 23. Therefore, the atomic mass number of this sodium atom is 23.
If an atom contains 7 protons and 8 neutrons its atomic mass is?
The atomic mass of the isotope 15N is 15,000 108 898 2(7).
If the atomic mass of an atom is 38 and the atom contains 15 protons how many neutrons does the atom contain?
Protons and neutrons each have an atomic mass of 1 So, 38-15=23 Neutrons
What is Atomic mass units of an atom that contains 8 protons 9 neutrons 8 electrons?
The atomic mass unit of an atom is the sum of the protons and neutrons in its nucleus. In this case, with 8 protons and 9 neutrons, the total atomic mass unit of the atom would be 17. The number of electrons does not significantly affect the atomic mass unit of an atom.
Does an atom of aluminum and an atom of gallium have the same atomic mass?
No, an atom of aluminum and an atom of gallium do not have the same atomic mass. Aluminum has an atomic mass of approximately 26.98 atomic mass units, while gallium has an atomic mass of approximately 69.72 atomic mass units.
What is the atomic mass number of an atom of sodium that contains 12 neutrons?
The atomic mass number of an atom is the sum of its protons and neutrons. Sodium typically has 11 protons, so if the atom has 12 neutrons, the atomic mass number would be 23 (11 protons + 12 neutrons).
Is a proton the least mass?
In an atom, there are 3 types of particles: protons, neutrons and electrons.Theoretically, protons and neutrons weight 1 Atomic Mass Unit. An electron weights 1/1836 of an Atomic Mass Unit. Therefore, in an atom, electrons weigh the least.
How do you determine the atom the atomic mass of an atom?
Proton + Nuetron = Atomic Mass
What is a mass number atom equal too?
An atom's mass indicates how many protons and neutrons it contains in its nucleus, since electrons have such small mass relative to them. This is also known as atomic mass.
