To find the total mass of an atom, you sum the masses of its protons, neutrons, and electrons. Although electrons contribute very little to the overall mass, the combined mass of protons and neutrons, which are located in the nucleus, accounts for most of the atom's mass. The Atomic Mass can be found on the Periodic Table, typically expressed in atomic mass units (amu), which reflects the average mass of the atom's isotopes. For a more precise calculation, you can use the actual masses of protons (approximately 1.007 amu) and neutrons (approximately 1.008 amu) along with the negligible mass of electrons (approximately 0.0005 amu).
What else can I help you with?
How do you you find the mass number of an atom?
To find the mass number of an atom, you add together the number of protons and neutrons in the nucleus of the atom. The atomic mass listed in the periodic table is the weighted average of the mass numbers of all isotopes of that element.
How do you define the atomic mass of an element?
The total mass of the atom. In other words the total mass of the protons and neutrons of an atom
What is the total amount of protons and neutrons in an atom?
The total amount of protons and neutrons in an atom is its mass number.
Is An atom's atomic mass is the total mass of all of its electrons and protons?
No, an atom's atomic mass is the sum of the total number of protons and neutrons in its nucleus. Electrons have such a tiny mass that they are usually not included in the calculation of an atom's atomic mass.
Why do you subtract the atomic number from the mass number?
We can find atomic mass and mass number in chemical elements. Atomic mass is about weight of the atom. Mass number is about total of neutrons and protons.
How do you you find the mass number of an atom?
To find the mass number of an atom, you add together the number of protons and neutrons in the nucleus of the atom. The atomic mass listed in the periodic table is the weighted average of the mass numbers of all isotopes of that element.
How do you define the atomic mass of an element?
The total mass of the atom. In other words the total mass of the protons and neutrons of an atom
What is the total amount of protons and neutrons in an atom?
The total amount of protons and neutrons in an atom is its mass number.
What is the atomic mass of an element the number?
We can find Atomic Mass and mass number in chemical elements. Atomic mass is about weight of the atom. Mass number is about total of neutrons and protons.
What is the mass number and what equation can it be written in?
We can find atomic mass and mass number in chemical elements. Atomic mass is about weight of the atom. Mass number is about total of neutrons and protons.
What is the total mass of the protons and neutrons in an atom called?
The total mass of the protons and neutrons in an atom is called the atomic mass or mass number. It is often represented by the symbol A.
Is An atom's atomic mass is the total mass of all of its electrons and protons?
No, an atom's atomic mass is the sum of the total number of protons and neutrons in its nucleus. Electrons have such a tiny mass that they are usually not included in the calculation of an atom's atomic mass.
Why is the atomic mass number not a whole number?
We can find Atomic Mass and mass number in chemical elements. Atomic mass is about weight of the atom. Mass number is about total of neutrons and protons.
Why do you subtract the atomic number from the mass number?
We can find atomic mass and mass number in chemical elements. Atomic mass is about weight of the atom. Mass number is about total of neutrons and protons.
What is the same about a atomie mass and atomie mass number?
We can find atomic mass and mass number in chemical elements. Atomic mass is about weight of the atom. Mass number is about total of neutrons and protons.
How do you find an atomic mass?
It is nothing but the total no of protons and electrons .So it is found by summing the total no protons and electrons present in an atom It is not electrons but the total of neutrons and protons present in the nucleus of any atom.
What is the difference between mass number atomic mass and atomic number?
Mass number is the total number of protons and neutrons in an atom's nucleus. Atomic mass is the average mass of an element's isotopes taking into account their relative abundance. Atomic number is the number of protons in an atom's nucleus, which determines the element's identity.
