Why does radiation decrease over time?

1 answer:

8 0

Radiation decrease over time due to the concentration of radioactive atoms and the concentration decreases as radioactive particles are emitted (Option D).

<h3>What is radiation?</h3>

Radiation refers to the transmission of energy by means of subatomic particles that travel as waves.

Radioactive isotopes are also known as radioisotopes, which have unstable combinations of subatomic particles (i.e., neutrons or protons) in their atomic nuclei, and thus may emit alpha particles, gamma rays or beta particles.

Radioactive isotopes such as C14 lost (emit) energy per unit of time, which is known as radiation or radioactive decay.

In conclusion, radiation decrease over time due to the concentration of radioactive atoms and the concentration decreases as radioactive particles are emitted (Option D).

What type of bond forms between two oxygen atoms

mr_godi [17]

Answer:A double convalescent bond is where two pairs of electrons are shared between the atoms rather than just one pair. Two oxygen atoms can both achieve stable structures by sharing two pairs of electrons as in the diagram.

Label each transition in this flow chart as a chemical change or a physical change

Elodia [21]

1) Left up: a chemical change. We can see new substance (red-blue) is formed from one blue and one red atom.

In chemical change new substances are formed, the atoms are rearranged and the reaction is followed by an energy change.

2) Left down: a chemical change. We can see new substance (red-blue) is formed from two blue and one red atoms.

3) MIddle: a physical change. There is no new substance. Bonds are not broken.

4) Right up: a chemical change. Bonds are broken.

5) Right down: a physical change. Change of state of matter.
