A type of covalent bond where both shared electrons come from a single atom (e.g., Ammonium ion - NH4+cap N cap H sub 4 raised to the positive power Important Chemical Reactions chemistry notes ssc

: Physical changes are reversible and do not form new substances, whereas chemical changes are irreversible and result in new substances.

Focus on these high-yield areas frequently seen in previous years' papers:

: The force of attraction between conduction electrons and positively charged metal ions. Types of Chemical Reactions Combination : Two or more reactants form one product ( Noble Gases or Inert Gases (Helium, Neon, Argon,

). They feature high melting points and conduct electricity in molten or aqueous states.

Discovered by J.J. Thomson using the cathode ray tube experiment.

Substances formed by the chemical combination of two or more elements in a fixed ratio by mass (e.g., Water - H2Ocap H sub 2 cap O , Carbon Dioxide - CO2cap C cap O sub 2 Matter and Its Composition

Atoms of the same element having the same atomic number but different mass numbers (e.g., Protium 11Hsub 1 to the first power cap H , Deuterium 12Hsub 1 squared cap H 13Hsub 1 cubed cap H

Chiefly consists of Butane and Propane . Ethyl Mercaptan (a sulfur compound) is added to give it a distinct odor for leak detection.

) is the only non-metal that remains liquid at room temperature.
