Indeed it does. Deuterium, a heavy Hydrogen isotope weighs roughly twice as much as ordinary Hydrogen, and Tritium, the other hydrogen isotope weighs roughly thrice as much. [1H, 1.007; 2H, 2.014; 3H, 3.016.]
There is a small discrepancy due to 'binding energy'.
As far as ordinary radioactive isotopes are concerned, they lose mass when they eject a particle. Some of this mass is the ejecta, some is the 'binding energy'.

Why do Oscar fish change colors and start digging?
Oscar fish change colors when they are stressed. They dig because they are curious.
How will holding a mirror in front of a fish change its behavior?
it depends what fish u have if u have a gold fish it would have change their behavior and it will think its another fish
How do fish get their color?
Some fish such as cichlids will change color as they mature. Another reason for fish to change color is stress. When fish stress out they can loose almost all of the color until they calm down.
What is an air bladder?
An air bladder is an internal organ used by fish to control their buoyancy, which allows them to maintain or change depth depending on their density.
When tiger fish get sick what color do they change?
black
How is the density of a fish controlled?
Fish control their density with a gas-filled organ called a swim bladder. The average density of a particular fish's tissues, not including gas in the , is 1070 kg/m^3.
Does the shape of an object change its density?
Changing the shape CAN change the density. If you change it into a smaller shape, then you increase the density. However the mass will not change.
Is a change in density a chemical change?
Density is a physical property.
How do fish use density in order to move in the water?
Fish use density in order to move in the water since they do not have lungs. When the density of water keeps changing, fish use it to move and thereby using less energy.
Why does changing shape of an object dose not change the density?
Changing the shape CAN change the density. If you change it into a smaller shape, then you increase the density. However the mass will not change.
Why are fish not moving when you change the water?
The density of a fish is much smaller than the density of water, therefore the fish does not sink, but it should float. The only thing that keeps the fish from floating to the surface are their swim bladders. They are organs inside the fish that contain gas to balance out the density of the fish and make the fish achieve neutral buoyancy and stay in the water.
How do you change density?
To change density there are three ways. You can change the shape, mass or volume of the object
If an objects volume is unchanged then how will its density change?
It won't change. Density is volume divided by mass, so if volume doesn't change, density doesn't change unless you change the mass of the object.
How does the density of the metal in the crushed can compare with the density of the metal before the can was crushed?
The density of the metal doesn't change when you crush a can.
What does stocking density mean?
i love fish
When you cut something in half like a candy bar does the density change?
The density does not change.
How can you change density of a substance?
You can change the density of a substance by changing its volume. Density is equivalent to mass over volume. So changing the volume affects density.
