The electron is the only subatomic particle that has a negative charge
Answer:
Answer is: 20 min.Bismuth 214 decay mode to lead is beta minus decay and alpha decay.Beta decay is radioactive decay in which a beta ray and a neutrino are emitted from an atomic nucleus.
There are two types of beta decay: beta minus and beta plus. In beta minus decay, neutron is converted to a proton and an electron and an electron.Alpha decay is radioactive decay in which an atomic nucleus emits an alpha particle (helium nucleus) and transforms into an atom with an atomic number that is reduced by two and mass number that is reduced by four.
Explanation:
Answer:
3
Explanation:
To balance the equation, you need the same number of each atom on both the left and right sides of the equation.
The balanced equation would be:
2 Fe + 3 S ---> Fe2S3
You then have:
2 Fe on both sides
3 S on both sides
