100

What are groups?

These are the vertical columns on the table where all the elements act like 'family' and have similar traits

100

What is density?

This is a physical property that measures how heavy or packed together a substance is for its size.

100

What is the nucleus?

This is the brain or the center of the atom where all the mass is.

100

What is the solute?

In a mix of Kool-Aid and water, the powder is this part of the solution.

100

What are reactants?

In a science experiment, these are the ingredients or the stuff you start with.

200

What is the atomic number?

This is the number at the top of an element's square that tells you how many protons it has.

200

What is flammability

If a substance can easily catch on fire, it has this chemical property.

200

What are atoms?

These are the tiny, invisible building blocks that make up everything in the universe.

200

What is a homogeneous mixture?

This is a well-mixed mixture where everything looks exactly the same throughout.

200

What is the Law of Conservation of Mass?

This law says you can't just create or destroy matter it has to go somewhere.

300

What are metals?

You can find these on the left side of the stairs on the periodic table they’re usually shiny and good at conducting heat

300

What is a chemical change?

When you see bubbles, a color change, or a weird smell, it’s a big sign that this has happened.

300

What are electrons?

These are the negative particles that zoom around the outside of the nucleus.

300

What is a heterogeneous mixture?

A bowl of Chex Mix is this kind of mixture because you can easily see and pick out the different parts.

300

What is 50g?

If you have 50g of reactants, you have to end up with exactly this much product.

400

What are the Noble Gases?

This is the group of 'snobby' gases on the far right that don't like to react with anyone else.

400

What is a precipitate?

This is what you call a solid that suddenly forms when you mix two liquids together.

400

What is a compound?

This is what you get when you chemically bond two or more different types of atoms together.

400

What is the universal solvent?

Water is called this because it’s really good at dissolving almost anything.

400

What is gas?

If you burn something and it seems to lose weight, the missing mass usually turned into this.

500

What are Halogens?

This group of elements is super reactive because they only need one more electron to be happy and full.

500

What is a physical change?


Crushing a can or melting an ice cube are examples of this, because the substance is still the same thing.

500

What are protons and neutrons?


These two particles are found inside the nucleus and give the atom its mass.

500

What are physical ways?

Because the parts of a mixture aren't stuck together chemically, you can use these types of ways to separate them.

500

What is balanced?

To show that mass is saved, you have to make sure both sides of a chemical equation are this.
