OILRIG:
Oxidation is loss (of electrons)
Reduction is gain (of electrons)
so...
The first one is an oxidation half-equation as the Sn loses electrons;
The second one is a reduction half-equation as the Cl₂ gains electrons
Answer:
C is the correct answer
Explanation:
The moon cycle is last 29.5 days
The correct statement is <span>(4) All atoms of a given element must have the same atomic number.
Atoms come in different isotopes(which have different mass), which differ in the number of neutrons, but are still the same element (this tells you why the other options are bad).

Answer:
The correct answer is: Electron
Explanation:
Electron (e⁻) is the negatively charged subatomic particle that has an electric charge of -1e (−1.6022 ×10⁻¹⁹ C). It was discovered by the English physicist, Sir Joseph John Thomson (J. J. Thomson) in the year 1897 by the <em>cathode ray experiment</em>.
In the cathode ray experiment, <u>Sir Joseph John Thomson used the </u><em><u>cathode ray tubes</u></em><u> </u><u>to conclude the presence of negatively charged small subatomic particle, known as electrons, in all atoms.</u>
