Physical Science Mid Term Exam Review

Front

What type of chemical bond is formed by the electrostatic force between a positive ion and a negative ion?

Back

Ionic bond: A type of chemical bond that occurs when a positive ion (cation) and a negative ion (anion) attract each other due to their opposite charges.

Front

What describes a stable binary ionic compound?

Back

A stable binary ionic compound consists of two ions with opposite charges that combine to have a net charge of zero.

Front

What are the nuclear reactions that produce energy by splitting or joining nuclei?

Back

Fission and Fusion: Fission is the splitting of a nucleus, while fusion is the joining of nuclei, both releasing energy.

Front

What is the formula for the compound formed when aluminum ions (Al3+) and chloride ions (Cl-) unite?

Back

AlCl3: The formula indicates that three chloride ions combine with one aluminum ion to balance the charges.

Front

What is the biggest disadvantage of using nuclear power to produce electricity?

Back

Nuclear waste must be safely stored for many years, posing long-term environmental and safety challenges.

Front

Define ionic bond.

Back

An ionic bond is a type of chemical bond formed through the electrostatic attraction between oppositely charged ions.

Front

What is a cation?

Back

A cation is a positively charged ion that results from the loss of one or more electrons.

Front

What is an anion?

Back

An anion is a negatively charged ion that results from the gain of one or more electrons.

Front

Explain the process of nuclear fission.

Back

Nuclear fission is the process where a heavy nucleus splits into two or more smaller nuclei, releasing a significant amount of energy.

Front

Explain the process of nuclear fusion.

Back

Nuclear fusion is the process where two light atomic nuclei combine to form a heavier nucleus, releasing energy.
