Chemistry S1 Review (without electron configurations)

Front

What are the states of matter?

Back

The states of matter are solid, liquid, gas, and plasma. Each state has distinct properties based on particle arrangement and energy.

Front

What is the mass number of an atom?

Back

The mass number is the total number of protons and neutrons in an atom's nucleus.

Front

What is an endothermic process?

Back

An endothermic process is a reaction or change that absorbs energy from its surroundings, often in the form of heat.

Front

What happens to particles in a liquid?

Back

Particles in a liquid are relatively close together, allowing them to flow but not easily compress.

Front

What is alpha decay?

Back

Alpha decay is a type of radioactive decay in which an atomic nucleus emits an alpha particle, consisting of 2 protons and 2 neutrons (a helium nucleus).

Front

What is the difference between an element and a compound?

Back

An element is a pure substance made of only one type of atom, while a compound is made of two or more different types of atoms chemically bonded together.

Front

What is the significance of the periodic table?

Back

The periodic table organizes elements based on their atomic number, electron configuration, and recurring chemical properties.

Front

What is a chemical reaction?

Back

A chemical reaction is a process that leads to the transformation of one set of chemical substances to another.

Front

What is the law of conservation of mass?

Back

The law of conservation of mass states that mass is neither created nor destroyed in a chemical reaction.

Front

What is a solution?

Back

A solution is a homogeneous mixture of two or more substances, where one substance (the solute) is dissolved in another (the solvent).
