How do valence electrons change across the periodic table?

Back

As you move from left to right on the periodic table, the number of valence electrons increases.

Front

What is the charge of an anion?

Back

An anion has a negative charge.

Front

What are thermal boundary layers?

Back

Thermal boundary layers are the boundaries between fluid layers where heat enters or leaves a convection cell.

Front

What is relative humidity?

Back

Relative humidity measures the percentage of water vapor in the air compared to the maximum amount the air can hold at a given temperature.

Front

Define an ion.

Back

An ion is an atom or molecule that has a net electrical charge due to the loss or gain of one or more electrons.

Front

What is the difference between cations and anions?

Back

Cations are positively charged ions, while anions are negatively charged ions.

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 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 chemical reaction?

Back

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