Elementary particles are not made up of other particles. Elementary particles can also make up larger particles making larger objects. When you think of an elementary particle, think of fermions, which are one type of the particles!

The temperature can affect the size of an atom. The hotter it is, the larger and farther away the components of an atom get from one another. In colder conditions, they're closer together and thus the atom is smaller in size.

Neutrons do not have any charge, unlike protons, which are positively charged. Did you know that neutrons are made up of two down quarks and one up quark?

Each element on the periodic table of elements has an atomic number. Its number is determined by the amount of protons in the nucleus. For example, hydrogen's atomic number is 1, meaning that there is only one proton in the nucleus.

This is true. In its liquid form, it has important qualities that make it fit for use in vehicles such as submarines. Did you know that it is also magnetic when in its liquid form?

An isotope is the same element but one has less or more neutrons than the other. Isotopes can be any of the elements as there are no exceptions. This can also affect the mass of the elements, as they will not be equal.

Mercury becomes a liquid at room temperature because of its low boiling point. But did you know that there is also another chemical that can do that as well? It's bromine!

The Bohr model is a diagram that shows the electrons that orbit the nucleus. The model can also show the amount of energy being generated and it is a simplified way to learn about atoms.

Subatomic particles are tiny pieces of particles that are even smaller than an atom. Often, these are the particles that make up the atoms themselves.

This is false. The softest mineral in the world is in fact talc. Have you ever heard of Mohs Hardness scale? Talc gets a score of one for its hardness, the lowest on the scale!

In order to make a molecule, there need to be at least two atoms that are fused together. The way they become fused together is through a chemical bond, that can include as many atoms as possible.

This process is called redox, which is a mix of reduction and oxidization, the names used for each of the processes. These processes also affect the oxidization number because of the number of electrons being moved around.

Plasmatic bonds are not a type of chemical bond. There is one other bond which was not mentioned, and that is hydrogen bond. Bonds are important in creating compounds like water or ammonium.

H20 is a molecular formula that means one part hydrogen, two parts oxygen. The formula also refers to the amount of atoms in the elements.

This is true. For example, this is why balloons are filled with helium, and it's also what makes them float! But did you know that the higher you go, the thinner the oxygen gets?

The law of constant composition calls for equal elements and equal mass. It is a rule for all elements that generally is followed. It's common for the elements to be measured in a ratio format to better understand the parts in the compound.

Rest mass and volume work together to make up matter, which is also made of particles. Did you know that matter can come in all different forms? Solid, liquid and even gas can all be classified as matter.

Oxygen is not one of the noble gases, as there are only six of them. The other three are radon, krypton and argon which fit the bill. Oganesson is a very rare element, in fact only a few atoms of it have ever been detected!

Biochemistry is all about chemicals within the bodies of living things. The chemicals that are studied in this area are things like protein and carbohydrates and how they work within the body.

This is false. The element that does this is actually water. As it turns into ice, the molecules expand, making the ice take up more volume.

Astrochemistry is the study of molecules and how they work in space. This can be in relation to molecules that are close to home and in our solar system as well as molecules beyond.

During a chemical reaction, the bonds of the atoms break as the entire composition transforms. The reaction can change the entire form of the substance.

This law is all about how light travels through a chemical or substance, with emphasis on the composition of the substance. It is calculated through an equation that takes the radial flux to determine how light is absorbed.

Charles's Law measures the volume of a substance when it is exposed to heat. Most of the time, the volume of gas goes up when it is hotter, as it starts to expand.

This is false. Ozone is the element produced by a lightning strike. Did you know that this is actually what creates the smell after a thunderstorm?

J.B. van Helmont was years ahead of his time living in the late 1500s to 1600s. He discovered carbon dioxide and did extensive work in the field of chemistry that laid the foundation for the subject we study today.

Chemistry is very important to two fields: biology and physics. They all work hand in hand and help us to understand science as a whole.

Homonuclear is a term used for a single element. For example, hydrogen is a homonuclear element and it also has only a single atom in it.

This is a word you don't hear every day! Enological chemistry is used to mix the right compounds into wine. Perfecting the chemistry of wine can be the key to making it taste great!

This is true. Carbon is actually in more than just diamonds. You'll find the substance in items like graphite pencils and it is even found within ourselves.

Gallium is a metal that will melt in your hand due to the heat. This is because the substance has a very low boiling point, meaning that our body heat is enough to break it down.

The Mpemba effect is about hot water freezing faster than cold water does. There is still a lot of debate over whether this works, and under what circumstances.

Dry ice is a form of carbon dioxide that is even colder than regular ice that is made of H20. Although it is cold, did you know that you can actually get burns if you touch dry ice?

Before you get a chemical compound, a chemical bond must take place. This is where two atoms attract to each other in order to create the compound. These bonds can be shown through a Lewis dot chart.

This is true. Antimatter is the opposite of matter. The difference is that antimatter has antiprotons, antineutrons and positrons that are directly opposite to those found in matter. No one has yet found stable antimatter!
