Answers
Answer:
a) Ans :-
each of two or more forms of the same element that contain equal numbers of protons but different numbers of neutrons in their nuclei, and hence differ in relative atomic mass but not in chemical properties; in particular, a radioactive form of an element.
b) Ans :-
i) Aluminum + Hydrochloric acid that gives raise to Aluminium chloride + Hydrogen (Gas)
ii) Zinc sulphide + Oxygen that gives raise to Zinc oxide + Sulphur dioxide
iii) Ferric chloride + Sodium hydroxide that gives raise to Sodium chloride + Iron hydroxide.
c) Ans :-
i) Chadwick is best known for his discovery of the neutron in 1932. A neutron is a particle with no electric charge that, along with positively charged protons, makes up an atom's nucleus. Bombarding elements with neutrons can succeed in penetrating and splitting nuclei, generating an enormous amount of energy.
ii) Goldstein contributed greatly to the study of cathode rays. He discovered protons with the experiments he did with cathode rays which would knock electrons of atoms and attract them to a positively charged electrode.
