Matter is anything that has ______and ______.
______was the Russian scientist who organized the periodic table of elements that we know today. He arranged the known elements together based on their similar properties. More importantly, he made accurate predictions about undiscovered elements.
The columns of elements on the periodic table are called ______or ______or ______. The noble gasses are a family that starts with ______and ends with ______. This family of elements is known for their properties of being ______
______. The Halogen family starts with the element ______and ends with the element ______. This family of elements is known for their properties of being ______.
The rows of elements that are arranged horizontally are called ______. As you go left to right on the periodic table, these elements gain one ______. As you go left to right in these rows, the elements also gain ______in their outer (valance)shells.
Color or highlight the most reactive column(or family, or group) in the periodic chart above yellow.
Which atom has the fewest number of protons in its nucleus? ______how many protons?_____
Which atom has the most protons in its nucleus? ______how many protons?_____
If the element Fluorine (fluoride) is so toxic, why do we put it in our toothpaste? ______
The fact that fluorine is toxic is a ______property.
Put an X in the box to indicate if the example is a physical or chemical property of matter.
Remember, a physical property describes something using our 5 senses, where a chemical property is indicated by the warning signs. Chemical properties describe how a substance could possibly change permanently.
