BRAINLIEST TO THE BEST ANSWER. radium-226 is unstable. What is the process that allows the nucleus of radium-226 to become more stable? Question 14 options: hydrogen bonding nuclear fusion radioactive decay ionic bonding covalent bonding

Radioactive decay would be most suitable for radium-226 to be more stable. Radium-226 has 88 protons, but 138 neutrons. Thus, it would want to decay, in order to get rid of some of the neutrons, and maybe transform into another element.

I just took the quiz and got 100

answer is: c. the experiment shows that the red substance experienced a chemical change.

this is chemical change (chemical reaction), because two new substances are formed (metalig liquid and gas), the atoms are rearranged and the reaction is followed by an energy change.

this is example of chemical decomposition.

chemical decomposition (analysis) is the separation of a single chemical compound into its two or more elemental parts or to simpler compounds.  

chemical decomposition is opposite of chemical synthesis.

plants need sunlight, water, and carbon dioxide to make food. plants use the raw materials of water, nutrients they absorb from soil, and carbon dioxide to make sugars the plant can use. energy from the sun and chlorophyll are also needed.
