Radioactive Particles
What particle has the strongest penetrating ability?
gamma
When an atom releases an alpha particle, this value decreases by 2.
atomic number
This type of reaction occurs when small nuclei combine into a larger nucleus.
Fusion
The stability of a nucleus depends largely on the ratio of these two particles.
neutrons and protons
This process can be used to determine the age of ancient remains.
carbon dating
What type of emission causes the atomic number to increase by 1?
beta decay
This process changes one element into another element.
transmutation
The splitting of a heavy nucleus into smaller nuclei is called this.
fission
Naturally radioactive elements have nuclei that are this.
unstable
Scientists can make stable atoms radioactive by doing this.
bombarding them with particles
What particle has a positive charge and the same mass as an electron?
positron
The missing particle in a nuclear equation has a mass number of 0 and a charge of -1.
beta
Compared to chemical reactions, nuclear reactions release this kind of energy (larger? smaller? the same? cant be determined?)
larger amount of energy
This radiation is electromagnetic energy with no mass or charge.
gamma rays
This is one advantage of nuclear fission.
producing large amounts of energy
What particle cannot be deflected by an electric field?
gamma or neutron
A balanced nuclear equation must conserve both charge and this quantity.
mass number
In nuclear reactions, what is mass converted into?
energy
Arrange alpha, beta, and gamma from least to greatest penetrating power.
alpha, beta, gamma
Sodium-24 becomes magnesium-24 after releasing this particle.
beta particle
What particle is made of 2 protons and 2 neutrons?
alpha particle
In beta decay, what does a neutron change into?
a proton
This type of transmutation is caused by bombardment with particles.
Artificial transmutation
