What is a nucleus?
Center of the atom. The mass of an atom is found here.
What elements is the fusion reaction staring with. He + Li --> B
Helium and Lithium
What two atoms add together to find mass?
Protons + Neutrons
How do you find the starting total mass of the reaction?
You add the mass of the atoms being added.
What is nuclear fusion?
The process that produces energy in a star.
what is the total starting mass of this fusion reaction?
he+Li --> B
10.94amu
What is something neutrons and protons have that electrons don't?
Mass
What is the total final mass of a reaction?
It is just the mass of the ending atom.
What is a atomic number?
Used to identify the name of the element. Found on the periodic table.
What elements is the fusion reaction ending with?
He + Li-->
Boron
What happens if you don't have a proton?
It won't be an atom
How do you calculate the percent change in a Fusion reaction?
Final mass- starting mass/ starting mass x 100
What are an Isotopes?
Two or more atoms with the same numbers of protons, and a different number of neutrons.
What does negative percent mean in this equation?
A negative percent change means that it is generated from the missing mass.
What particles does nuclear fusion start with?
It starts with two protons colliding.
What is an example of a fusion reaction equation?
h+h+h+h=he energy
What is a proton?
Positive particle found in the center of an atom. Equal to the atomic number.
What is the total final mass of this fusion?
10.81
What is the final product of nuclear fusion?
energy
How to find if it is a positive or negative change.
Subtract the starting mass and final mass to see if you have a negative change and if you lost energy or gained, if your starting mass is greater than your final it is likely to be negative change.
