Valence Electrons
Name an element with 7 valence electrons
Florine, Chlorine, Bromine, Iodine, Astatine
What is the pattern of the Periodic Table?
It goes by Atomic Number (by 1)
What does the Bohr Model look like and what was it used for?
It looks exactly like an atom and used to number of electrons in an atom.
How many valence electrons are needed in a atom to achieve stability?
8 is the usually the "Magic Number".
What’s the difference between Metals and Non-metals?
Metals are a great conductors, they're also malleable and ductile and generally shiny, while nonmetals is he complete opposite.
How many valance electrons can fit in one ring?
8 MAX (except the first ring)
What five elements only need two electrons to be stable?
Hydrogen, Helium, Lithium, Beryllium, Bromine
Who created the Bohr model?
Neils Bohr (Danish Physicist)
How many particles does K (Potassium) have? (Neutral Atom)
P: 19
N: 19
E: 19
What’s the properties of a metalloid?
Properties of both Metals and Nonmetals.
How many valence electrons does H (Hydrogen) have?
1 valence electron
How many common groups are in the Periodic Table?
8
When was the Bohr model created/purposed?
1913 Neils purposed the idea and created the Bohr model.
Whats the max amount of protons that can be held in an atom?
112 protons (up to date)
What group makes up the stair ladder in the Periodic Table?
Metalloids
What does it mean if a atom has 8 valance electrons?
It means the atom is stable.
Which side of the Periodic Table loses/gains valence electrons to achieve stability?
Right - Gains
Left - Loses
What does the Bohr model represent?
An atom.
What is an atom?
A small piece of matter that makes up everything.
What group is the left/right side of the Period table?
Metals-Left
Nonmetals-Right
Can any element have 8 valence electrons? If so explain why.
Yes, because any element can become stable.
How the properties of an element change?
It changes depending on the number of valence electrons.
What atoms can you use the Bohr model for?
All of them.
How can you find the average atomic mass of an atom?
The Periodic Table will tell you the most common.
What is the biggest group?
Metals
