Atoms
Atoms are the building blocks of all this.
What is matter?
The flammability of a substance is this kind of property.
What is a chemical property?
This is the ability to do work.
What is energy?
This is the big number in front of a chemical formula that tells you the amount of molecules in the substance.
What is the coefficient?
Horizontal rows across the periodic table are called this.
What are periods?
Particles that float around the nucleus of an atom.
What are electrons?
The color of a substance is this kind of property.
What is a physical property?
These are listed on the right side of a chemical equation.
What are the reactants?
This states that in a chemical reaction, the total mass of the reactants must equal the total mass of the product.
What is the Law of Conservation of Mass?
This group of metals are mostly man-made and all of them are radioactive.
What is the Actinide Series?
These are atoms with different numbers of neutrons.
What are isotopes?
Iron, cobalt, and nickel all have this physical property.
What is magnetism?
Group 18, also called this, do not react with anything at all.
What are Noble Gases?
A change in color is a clue that a new this has formed.
What is a substance?
Groups on the periodic table are also called this.
What are families?
This signifies the amount of protons in an atom.
What is the atomic number?
This type of property describes the characteristics of a substance that can be observed without changing it into a new substance.
What is a physical property?
This is the first element, which makes up over 70% of the atoms in the universe.
What is hydrogen?
This type of change can alter the appearance or form of matter, but it does not create any new substances.
What is a physical change?
Alkaline Earth metals react by losing this many atoms, which is also their group number.
What is two?
The nucleus of an atom has this kind of charge.
What is positive?
This type of property describes a substance's ability to change into another substance.
What is a chemical property?
If a substance is this, it makes a ringing noise when hit.
What is sonorous?
This states that every pure substance always contains the same elements combined in the same proportion by weight/mass.
What is the Law of Definite Proportions?
The first periodic table, made by Dmitri Mendeleev, had this many known atoms in it, with 3 blanks lefts for yet-to-be-discovered elements.
What is 63?
