Which statement describes what happens to elements during radioactive decay

1)  They release energy.

Explanation:

The radioactive decay of chemical elements is a phenomenon in which the unstable nucleus of an atom disintegrates becoming a more stable nucleus, but due to the decay, particles such as alpha and beta particles among others are released.

A Radioactive decays releases energy (it is important to remember that energy is not created or destroyed, only transformed), in order to move from a non-stable nucleus to a more stable one.

The radioactive decay has an exponential decay, which means that it is reduced steadily over time, and this depends on the element.

The statemente that best describes what happens to elements during radioactive decay is: 1)  They release energy.

the correct answer is - d. china has a large and growing population.

the fact that china has a large (the biggest) population, and it is still growing, doesn't hinder the agriculture production in the country. in fact, it can for increased production in the agriculture, since there's more labor force, as well the sheer mass of people produces lots of scientists that come up with new inventions as to how to improve this sector. nice example is the inner mongolia region in china, in general dominated by the gobi desert, but few scientist came up with a nice idea as to how to make the region productive by using plants that are very resistant to droughts, so lots of people have been employed, and the region is becoming greener and greener each year, and the production of food in this region is also increasing.
