Subatomic Particles
What are the three main subatomic particles and what are their charges?
protons- positive
neutrons- neutral
electrons- negative
What is the name of the number above the element name and symbol on the periodic table? What does it tell us?
Atomic Number- tells us the number of protons
Which of the two is the ability of an atom to attract electrons from the outside?
Electronegativty
What is the Bohr atom of Boron?
Two rings, first ring has two electrons and second/outer ring has 3 electrons.
What number is at the bottom of an element square on the periodic table?
atomic mass
What are valence electrons?
Electrons in the outermost orbital
What is a column on the periodic table called? What does it tell us?
Groups OR Families
It tells us that all of those elements have the same number of valence electrons.

How many valence electrons does Francium have?
*Hint- do not draw it out, think about rules of rows or columns to help you figure it out easily
1 valence electron
*Families or groups all have the same number of valence electrons, the first family all only have one valence electrons.
