Answer:
Covalent compounds.
Explanation:
Hello,
In this case, when forming chemical bonds in order to form compounds, we say that if electrons are shared, covalent compounds are to be formed and they usually have subscripts that need prefixes to be named, for instance phosphorous pentachloride (PCl5), dichlorine heptoxide (Cl2O7), carbon tetrachloride (CCl4) and many others.

Answer: the oxidation of the copper (it turning green)
Explanation:
Ions<span> are electrically </span>charged particles<span> formed when </span>atoms lose or gain<span> electrons. They have the same electronic structures as noble gases. Metal </span>atoms form<span> positive</span>ions<span>, while non-metal </span>atoms form<span> negative </span>ions<span>. The strong electrostatic forces of attraction between oppositely </span>charged ions<span> are called </span>ionic<span> bonds.</span>
Answer:
Solids.
Explanation:
In a solid object, particles are packed tightly together in fixed positions even if in a container.
Answer: b. common ion effect
Explanation: because the saturated ionic compound (the lead II chloride) precipitated when a soluble compound (sodium chloride) was added. The solutions had an ion in common causing one to precipitate. Therefore it is b.
