DUE 5 JUNE 2026



QUESTION 1

Answer the following questions:



1.1) Define the term “particle” as used in physical science.



1.1) In physical science, a particle refers to a very small piece of matter. The study
guide states: "All matter in the Universe is made of very small particles" (NST2601
Study Guide, 2020, p. 16).



1.2) The subatomic particle discovered by J.J. Thomson is the electron (NST2601 Study
Guide, 2020, pp. 17–18).



1.3) The scientist who proposed the billiard ball model of the atom was John Dalton
(NST2601 Study Guide, 2020, p. 17).



1.4) The electrical charge of a neutron is neutral (no charge) (NST2601 Study Guide,
2020, p. 25).

, 1.5) The maximum number of electrons that can occupy the second energy shell is
calculated using 2n2. For n=2n=2: 2×(2)2=82×(2)2=8 electrons (NST2601 Study
Guide, 2020, p. 30).




1.6) The atomic model that proposes fixed energy level orbits for electrons is the Bohr
model (planetary model) (NST2601 Study Guide, 2020, pp. 22–23).



1.7) The symbol that represents a proton is p+ (NST2601 Study Guide, 2020, p. 25).

(NST2601 Study Guide, 2020, p. 25).



1.8) The atomic number of chlorine on the periodic table is 17 (NST2601 Study Guide,
2020, p. 26).



1.9) The scientific term for atoms of the same element that have different numbers of
neutrons is isotopes (NST2601 Study Guide, 2020, p. 27).



1.10) The part of an atom described as the positively charged centre is the nucleus
(NST2601 Study Guide, 2020, p. 21).
