Question

If you can answer as many of these as possible that would be great, will give thanks, 5 stars, and brainliest :)


1. Considering the ​structure​ of the atom (our 2nd unit of Chemistry) what location of the
atom do you think nuclear chemistry deals with?
2. Look at the periodic table image in the notes (also use your own periodic table that
shows more information). What can you say about the size of the majority atoms
described as radioactive (colored purple on the periodic table image)?
3. What 2 features of nuclei make them likely to be radioactive?
4. Which 3 of the chemistry reference tables do you think you’ll be using during this unit?
5. What is your favorite particle from table O? Guess which particle is my favorite!
6. Which number on the periodic table identifies an element?
7. What does that number represent?
8. Ipso Facto (​aka therefore​): the number of _______indicates the identity of the _______
9. These notes include the word “spontaneous(ly)” which we used in the RedOx unit. What
does the word spontaneously mean?
10.List the particles from table O that have no mass
11.List the particles from table O that have no charge
12.List the particles from table O that have neither mass nor charge
13.List the negatively charged particle from table O
14.What does the word “transmutation” mean in the study of nuclear chemistry? Do you
think it’s aptly named?
15.Based on the description of transmutation and your answer to number 8 above , the
number of which subatomic particle must change for transmutation to occur?

Answer 1

Answer:

1. The nucleus of the atom as suggested by "nuclear" chemistry.
2. Radioactive element are generally very large due to both their high number of protons, neutrons, and electrons.
3. An excessive amount of protons or neutrons.
4. Periodic table, table O, and table N.
5. Personal opinion question.
6. The atomic number.
7. It represents the number of protons, and can also represent the number of electrons in a neutral atom (an atom with no charge).
8. Protons ---- element.
9. Random, self-generated.
10. Gamma radiation is the only thing on table O that is mass less. Close to being the same is Beta particles which have almost no mass.
11. Neutrons and Gamma radiation.
12. Gamma radiation.
13. Electrons and Beta particles.
14. To turn one element into the isotope of another. Yes, I believe it is aptly named because you are changing the identity of the element.
15. The number of protons because they are what define the identity of an element.

Goodluck!
