Which of the following elements tend to be radioactive? check all that apply. a. mgb. puc. fed. th

Explanation:

An atom which has greater difference in the number of number of protons and neutrons will be unstable in nature. This is because then nuclear binding energy will not be strong enough to hold the neutrons and protons together.

For example, and are both radioactive in nature due to large difference in the number of protons and neutrons.

Whereas for and there is not much difference in the number of protons and neutrons.

Thus, we can conclude that both Pu and Th elements tend to be radioactive in nature.

the focus of lesson 1 is newton's first law of motion - sometimes referred to as the law of inertia. newton's first law of motion is often stated as. an object at rest stays at rest and an object in motion stays in motion with the same speed and in the same direction unless acted upon by an unbalanced force.
