Which of the following is a good description of radioactivity?

• The energy necessary for the creation of zombies

• Elements that have unstable nuclei that may decay and result into transformation into a new element

• The way that atoms of elements clone themselves into new copies

• The method by which electrons are stripped from atoms to become charged particles

During this type of radioactive decay, a neutron splits into a proton and an electron, the proton stays in the nucleus raising the atomic number of the atom by one.

• alpha decay

• beta decay

• gamma decay

During this radioactive decay, gamma radiation is given off, but there are no other changes to the nucleus

• alpha decay

• beta decay

• gamma decay

The nucleus is held together by the ___________________________force.

• The Strong Nuclear Force

• The Weak Nuclear Force

• Electromagnetism

• Gravity
