These are the 3 subatomic particles that make up the atom
What are protons, neutrons, and electrons?
These are the name for rows
What are periods?
Elements are pure substances made up of only 1 type of these
What are atoms?
Compounds are combined this way
What is chemically?
What is heterogeneous?
Protons carry this type of charge
What is positive?
These are the vertical columns on the Periodic Table
What are groups/families?
The majority of elements on The Periodic Table are made up of these
What are metals?
Compounds are considered to be this type of substance
Mixtures are combined this way
What is physically?

What is neutral/no charge?
This Russian scientist arranged what we now know as The Periodic Table of Elements
Who is Dimitri Mendeleev?
This is the most important physical property of elements and Dimitri Mendeleev used it to arrange The Periodic Table of Elements
What is the Atomic Number (or number of protons in the nucleus)
This common compound is made from Na (Sodium) and Cl (Chlorine).
What is table salt? NaCl
Sweet tea is this type of mixture
What is homogeneous or a solution?
These are the electrons in the outermost shell or layer of the atom
What are valence electrons?
The elements are categorized at the state they appear in this temperature
What is room temperature?
This group has the most chemically reactive elements
Group 1-Alkali Metals
If a substance is a compound, it will have two or more of these in the chemical formula
What are elements?
Salad is this type of mixture
What is heterogeneous?
On The Periodic Table of Elements this will clue you in to how many valence electrons are present
What are groups?
These 2 categories were placed below the Periodic Table in order to make it shorter in width
Elements in Group 1 on The Periodic Table are rarely found alone in nature. This is due to the number of these
They have 1 valence electron which causes them to want to combine with other elements
This common compound is used in making DumDum lollipops and many other delicious treats!

A homogeneous mixture (like salt water) is also known as this
What is a solution?
