100
These are the positive particles inside an atom.
What are protons?
100
An atom is broken into 2 basic parts; the electron cloud and this.
What is a nucleus?
100
This person first laid out the periodic table of elements on cards and put it in order of increasing atomic mass.
Who is Dmitri Mendeleev?
100
The atomic number on the periodic table of elements gives you the number of these in an atom of the element.
What are protons?
100
The number of this type of particle of an atom determines what the element is.
What are protons?
200
These are the negative particles inside an atom.
What are electrons?
200
This is the core of an atom.
What is the nucleus?
200
Today's periodic table of elements is organized by this.
What is increasing atomic number? or What is by metals, nonmetals, and metalloids?
200
The atomic number on the periodic table of elements gives you the number of protons in an atom of the element. IF the atom has no charge, then it is also the same as the number of these in an atom of the element.
What are electrons?
200

How do we know if an atom is an isotope?

Different mass than Periodic Table
300
These are the particles that do not have a charge inside an atom.
What are neutrons?
300
The electron cloud contains these types of particles inside an atom.
What are electrons?
300
These are located on the left side of the periodic table of elements.
What are metals?
300
This is the number of protons plus the number of neutrons in an atom.
What is the atomic mass or mass number?
300

An atom has 3 electrons, 5 protons, and 5 neutrons; what element is it

What is Boron?

400
These are the building blocks of matter.
What are atoms?
400

What two particles weigh about 1 amu?

What is a proton and neutron?

400
These are located on the right side of the periodic table of elements.
What are nonmetals?
400
Using a periodic table of elements, you do this to find out how many neutrons are in an atom of an element.
What is subtract the atomic number from the atomic mass?
400

An atom has 3 electrons, 5 protons, and 5 neutrons;Isotope or Ion?

Ion

500

What two particles of the atom are in the nucleus?

What is protons and neutrons?

500

What particle does not weigh anything (roughly)

What is an electron?

500
These are located along the "zig-zag" line between the metals and non-metals.
What are metalloids?
500
85% of the periodic table of elements is made up of this type of element.
What are metals?
500
This is the name of the columns of the periodic table of elements. This is the name of the rows of the periodic table of elements.
What are groups? What are periods?
