Lesson 1.1
What are the three subatomic particles
Proton, neutron, and electron
Is a group on the periodic table horizontal or vertical
Vertical and there are 18 of them
How many valence electrons do elements--excluding Hydrogen and Helium--want?
8
Ionic bonding can be described as a "what" of electrons?
Transfer
Acids have a pH below...?
7
Where are electrons found?
Outside the nucleus or in "the electron cloud"
What is the name of group 17?
The Halogens
Where are valence electrons found?
In the energy level farthest from the nucleus
What type of elements bind together in a covalent bond?
2 or more nonmetals
What is the characteristic taste associated with acids?
Sour
What does Atomic number tell us about an element?
The number of protons that can be found in the nucleus of that atom.
What three things are found in a block of the periodic table?
Chemical symbol, atomic number, and mass number
How many Valence electrons does Gallium have?
3
What does a polar covalent bond mean?
An unequal sharing of electrons between two elements
What is another name for a positively charged Hydrogen ion?
A proton
Which subatomic particle is responsible for isotopes?
Neutrons
Sulfur
Name at least 2 qualities of metals--found on the left side of the periodic table
Ductile, Malleable, high heat transfer, luster, good conductivity
How many total electrons are held in a triple bond?
6
Do bases accept or donate a proton?
Accept
What did Rutherford's Gold Foil experiment reveal about the structure of the nucleus?
That there was a dense positively charged center which Rutherford called "the nucleus"
How did Dimitri Mendeleev originally organize his original periodic table?
By increasing Atomic Mass NOT by increasing Atomic number as the modern periodic table is organized by
Draw the orbital diagram and the dot diagram of Nitrogen
Drawings will vary
Draw the complete bond between H2O (Water)
Students need to make sure that they include polarity, and a sharing of electrons
What are the products of a neutralization reaction?
Salt and Water
