What happened to the mass of an atom that decays by alpha decay?
During alpha decay, an atom emits an alpha particle, which consists of two protons and two neutrons. As a result, the original atom loses mass equivalent to the mass of the alpha particle released. This loss of mass results in a decrease in the atomic mass of the parent atom, and according to Einstein's equation (E=mc^2), the lost mass is converted into energy, which is released during the decay process.
How is atomic mass affected by an alpha particle?
The atomic mass of an element decreases when it emits an alpha particle. An alpha particle consists of two protons and two neutrons, so when an atom undergoes alpha decay, it loses these four nucleons. This results in a decrease in the atomic mass number by four and the atomic number by two, transforming the original atom into a different element. Consequently, the atomic mass of the resulting atom is lower than that of the parent atom.
The relative atomic mass of an atom can be found by comparing the mass of the atom to the mass of?
The Hydrogen atom. Beware, Hydrogen has an atomic mass based on one proton, as it doesn't have a neutron. So Helium has a mass of four times Hydrogen.
What represents most of an atom's mass?
The nucleus of an atom represents most of an atom's mass.
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.

Do you increase or decrease in mass?
you increase or decrease mass by taking the mass out
Is an oxygen atom have twice the mass of a sulphur atom?
No, an oxygen atom does not have twice the mass of a sulfur atom. An oxygen atom has a mass of approximately 16 atomic mass units (amu), while a sulfur atom has a mass of approximately 32 amu. Therefore, a sulfur atom has twice the mass of an oxygen atom.
Which would have more of an affect on the mass of an aluminum atom removing ten electrons or one neutron?
Removing ten electrons would have a larger effect on the mass of an aluminum atom than removing one neutron. Electrons have very little mass compared to protons and neutrons, so removing ten electrons would significantly decrease the mass of the atom. Neutrons contribute roughly the same mass as protons, so removing one neutron would have a smaller impact on the overall mass of the atom.

Why the mass of hydrogen molecule is greater then the mass of hydrogen atom?
The mass of a hydrogen molecule is greater than that of a single hydrogen atom because a hydrogen molecule consists of two hydrogen atoms bonded together. When two hydrogen atoms bond to form a molecule, they share electrons, resulting in a decrease in the individual mass of each atom. However, the total mass of the molecule is slightly higher due to the binding energy that holds the atoms together.
What does adding A neutron to an atom's do to the atom's mass?
Adding a neutron increases the atom's mass by about 1 AMU assuming it remains stable.
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.
Is the mass of an iron atom any different from the mass of a copper atom?
Yes, the mass of an iron atom is different from the mass of a copper atom. The mass of an iron atom is approximately 56 atomic mass units, while the mass of a copper atom is approximately 63.5 atomic mass units. Therefore, there is a difference of about 7.5 atomic mass units between the two.
What will happen to the density if you keep the volume the same and you decrease the mass?
If you decrease the mass while keeping the volume constant, the density of the object will decrease. Density is calculated by dividing mass by volume, so a decrease in mass with a constant volume will result in a lower density.
