A bond formed between a metal atom and a non-metal atom in which electrons are transferred from the metal atom to the non-metal atom, forming ions. If an atom loses an electron, it becomes positively char...

Positive. The neutrons found in the nucleus have a neutral charge, however the protons are positively charged. Therefore the overall charge is positive.

Student should know complete combustion produces CO₂ and H₂O Once products are known, equation can be balanced as:  CH₄ + 2O₂ ---> CO₂ + 2H_2<...

Ethanol can be produced by hydrating ethene, through reacting it with steam under the influence of a catalyst e.g. phosphoric acid.

An atom is comprised of protons, neutrons, and electrons. Protons have positive charge and the number of protons is dictated by the proton number, which is the same as the number of electrons, which have ...
