Question

Please answer either True or False to the following questions... I forgot my Chem book at school and this stuff is due tomorrow.

TRUE or FALSE

1. Two atomic nuclei join together during nuclear fission.

2. gas molecules are ionized by a radioactive substance in a bubble chamber.

3. Iodine-131 can be used to study the function of the thyroid gland.

4. Radioisotopes are used to kill bacteria.

5. A skeleton of an ancient ish is found to contain one eighth the amount of carbon-14 thaht it contained when it was alive. Assuming that the half-life carbon is 5,730 years, the skeleton would be 11,450 years old.

6. Electrons in the outermost energy level are called oxidation electrons.

7. Covalent bonds form crystals.

8. The tendency of an atom to attract electrons is called electron affinity.

8. The combining capacity of an atom is described by its crystal lattice.

9. Malleable solids are substances whose molecules are very large.

10. A charged atom is called a molecule.

Answer 2

fake. it normally is helping. but it surely does not must be. simply ensure you examine relaxation of your items considering the fact that often you utilize celcius, however then there's a unit that's like joules in line with kelvin. and you then'd be screwed up. however yeah, def. fake. except your different conversions use kelvin as a unit, then actual.
