An experiment is set up to determine the type of radioactive decay coming from a certain hazardous nuclide. The analytical instrument used in this experiment detects the charge of the particles emitted from the nuclide. When interpreting the results of the experiment, it was discovered that the emitted particles had no charge at all. Which of the following could be the identity of these particles?A. Positrons B. Protons
C. γ particles
D. β particles

(C.) γ radiation

Explanation:

Gamma radiation, γ , does not consist of particles but a photon of energy. Hence, it has no mass or charge, allowing it to travel much faster than alpha or beta particles.

From the options, only γ-raiation does not have charge as opposed to positrons and protons which are + and beta which is either + or -.

answer: atomic mass was originally used to arrange elements on the periodic table, but is no longer used to organize the modern version.

explanation:

originally atomic mass was used to arrange elements on the periodic table from left to right in a row. each column then shows similar properties of elements of a group.

in modern periodic table, the atoms are arranged in increasing atomic number. as atomic number represents the number of protons in an atom which is unique for every atom.
