Atomic Personalities
This scientist is attributed with creating the modern periodic table.
Who is Dimitri Mendeleev?
The periodic table is arranged by increasing # of these.
What is the atomic number?
(also acceptable: What are protons?)
Atomic number 1
What is hydrogen?
This is the smallest particle of an element that still retains all the characteristics of that element.
What are atoms?
Group two of the periodic table
What are Alkaline Earth Metals?
This scientist created a still heavily used model of the atom that shows the electrons in orbits around the nucleus.
Who is Neils Bohr?
These are the horizontal rows on the periodic table.
What are periods?
I have an average mass of 192.22
What is Iridium?
This is the super dense center of the atom.
What is the Nucleus?

What are groups?
I am the basis of life as we know it.
What is Carbon?
When calculating the mass of an atom this is the mass of an electron.
What is zero?
