In the periodic table, a row is more scientifically known as this.
What is a period.
100
This is what Mendeleev discovered that led him to creating the periodic table. (Must give both reasons to get credit)
What is 1. There were elements missing and 2. There was an order to the elements.
100
This is the scientific name for the middle portion of the periodic table.
What is a nucleus.
100
This is the part of an atom with a positive charge.
What is a proton.
100
The majority of the periodic table is made of this broad category.
What are metals.
200
The periodic table is sorted by this number.
What is the number of protons, or atomic number.
200
In the periodic table, a column is more scientifically known as this.
What is a group or family.
200
The nucleus contains these two pieces.
What are the protons and neutrons.
200
This is the part of an atom with a negative charge that rotates around the outside of the nucleus.
What is an electron.
200
These are the three major categories found out the periodic table.
What are metals, metalloids, and non-metals.
300
This is the person who sorted the periodic table.
Who is Dimitri Mendeleev.
300
This is what groups have in common on the periodic table.
What are properties.
300
Orbiting outside the nucleus, can be found this part of the atom.
What are electrons.
300
This is the part of an atom located in the nucleus with no charge.
What is a neutron.
300
This is a physical property.
What is a property of a substance that you can see, taste, touch, hear, or smell.
400
This is how the periodic table is sorted.
What is by atomic number (or number of protons)
400
This makes up the total atomic mass of an atom. (Not to be confused with AMU-average atomic mass)
What are the protons, neutrons and electrons.
400
Describe an isotope.
An isotope has either more or less neutrons than it has protons.
400
This is the reason a neutral atom has its name.
There is a neutral charge because there is an equal amount of protons and electrons.
400
What is a chemical property?
What is a property that describes a chemical change- something happening that you can not see, smell, taste, touch, or hear. Flammability or ability to oxidize would be examples of chemical property. A chemical property describes a substance change whereas a physical property describes a change that does not change the substance.
500
This determines the kind of element and the element itself.
What is the atomic number, or number of protons. Hydrogen will also have an atomic number of 1. If there was more than 1 proton, hydrogen would not be hydrogen.
500
This makes up the AMU for an element.
What is the average atomic mass- includes the atoms mass in both normal and isotope form.
500
Describe a neutral atom.
A neutral atom has the same amount of protons and electrons.
500
These are 5 pieces of information you can learn by looking at an element's placement and "id card" on the periodic table.
What is atomic number, react-ability, number of protons, AMU, chemical symbol, its broad and specific category.
500
Describe the difference between an isotope and neutral atom.
An isotope deals with protons and neutrons, a neutral atom deals with protons and electrons.
