Which statements describe what is gained or lost during radioactive decay? check all that apply. atoms gain other atoms. elements take in energy. atoms lose smaller particles. elements gain smaller particles. energy and particles are released.

During radioactive decay ionizing particles and energy are released from the unstable atom.

The answer is;

In radioactive decay, large unstable isotopes (such as Uranium-283) decay into smaller more stable isotopes of different elements. In such nuclear decays, neutrons and radiation are released. The released neutrons are then used in the splitting of other unstable isotopes in the vicinity. Different isotopes have different half-lives which are the time take for the mass of a decaying element to decay by half.  

there are 35 white marbles

step-by-step explanation:

y- yellow marbles

4y + 5 = 45

subtract 5 from both sides

4y = 40

divide for from both sides

y = 10

plug in 10 to get 40 yellow marbles then subtract by 5 to get 35 marbles

thus there are only 10 yellow marbles
