P.T. symbols
Hydrogen
What is an electron?
A negatively charged subatomic particle
Where are the electrons located in an atom?
Around the nucleus in "orbitals, energy levels, or shells"
What does the charge of an element tell us about the # of electrons it has?
It tells us
a. how many valence electrons it has
b. how many of 1 element will bond with another
c. help us to determine the chemical formula for 2 given elements
What is a pirate's favorite element?
Arrrrrrrrrrrrggggggon.
What symbol is He?
Helium
What is a proton?
A positively charged subatomic particle
What are Valence electrons?
Electrons in the outermost shell, or the energy level of an atom
Which Periodic Group NEVER bonds with other elements?
The Noble Gasses
Name any type of chemical bond
Ionic, Covalent,Single, Double, Triple, Nuclear
What information does the Group # tell you about an element?
the # of valence electrons
What is a Lewis dot structure?
Diagrams that describe the chemical bonding between atoms in molecules.
What is the term used for the way we model an atom of an element by showing us how many valence electrons it has?
Lewis Dot Structure OR Electron Dot Structure
2+
What is an ionic bond?
bond between two oppositely charged elements or 1 element and 1 polyatomic ion
Elements get larger in diameter
Does it matter where the dots go on the Lewis dot structure?
No, it doesn't matter where they go.
Name any element that has 5 valence electrons
Nitrogen, Phosphorous, Arsenic, Antimony, Bismuth
How do we calculate the charge of any group of elements?
"8 People at the Party"
Decide if it's easier to kick them out or find more people for the party.
Then, + charges are for groups 1,2,3, and 4
- charges are for Groups 4, 5,6 7,
neutral charges are for Noble gasses only
What is the nuclear strong force
The force that bonds the protons and neutrons in the nucleus of an atom.
WHat is the one group of elements that NEVER bond with another element?
Noble Gasses or Group 18 or 8
What purpose does the Lewis dot structure serve?
Allows you to know how it will bond and how many bonds it'll form.
Hydrogen or Helium
Nope
What are ionic compounds made of?
1 positively charged element and 1 negatively charged element.
