What else can I help you with?
The region in an atom that contains most of the mass is called?
Most of the atom's mass is concentrated in the nucleus.
What part of the atom contains most of its mass?
The nucleus, made up of protons and neutrons, contains most of an atom's mass.
Where is the most of the mass in an atom?
Most of the mass in an atom is in the nucleus. The protons and neutrons are about the same weight, 1 amu. The elecrtons are 1/1840 of the mass of an proton. Neutrons are 2000 times heavier than electrons and protons have an equal mass of neutrons
What is the mass of an aluminum atom?
An Aluminum atom is 26.9815 AMU on *average*.
The particle in the nucleus of an atom with no charge?
It is called the nucleus and has a mass unit number of one.
Why is the atomic mass scale also called the relative atomic mass scale?
All atomic masses are determined by comparing them to the mass of an atom of carbon12. One atomic mass unit equals one twelfth the mass of an atom of carbon12. That's why its called relativeatomic mass.
What is the mass of a calcium atom compared with the mass of a helium atom?
5
Atomic mass of an element?
The atomic mass of an element is the relative mass of its atom as compared with the mass of a carbon-12 atom taken as 12 units.
An atom has no mass?
An atom does have mass. The mass of an atom is primarily concentrated in its nucleus, which is made up of protons and neutrons. Electrons, which orbit the nucleus, have much less mass compared to protons and neutrons.
What is the average atomic mass compared to the atomic mass?
Atomic Mass is the number of protons and neutrons in an atom.
The of an element is defined as the average mass of an atom of the element compared to 112th the mass of an atom of carbon-12. What are the three missing words?
relative atomic mass
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 a twizzler a large or small mass?
It depends on the context. Compared to an atom it is huge, compared to the sun it is tiny.
What is the mass of calcium atom compared with the mass of helium atom?
The mass of a calcium atom is around 40 atomic mass units (u), while the mass of a helium atom is around 4 atomic mass units (u). Therefore, the mass of a calcium atom is 10 times greater than the mass of a helium atom.
What is the standard for atomic mass unit called?
One twelfth (1/12) the mass of a carbon-12 atom is one atomic mass unit (amu, or just u).
Where is all the mass of an atom concentrated in?
The mass of an atom is concentrated in its nucleus, which is composed of protons and neutrons. The nucleus is extremely small compared to the overall size of the atom, but it contains almost all of the atom's mass. Electrons, which are much smaller in mass, orbit around the nucleus.
How do you prove that volume of an atom is chiefly empty space?
The mass and volumes of electrons are not significant compared to the volume of an atom.
