Chapter 1
List 3 safety rules
Report all injuries or accidents, Long hair must be tied up, wear safety goggles
What is a chemical symbol
A symbol is a code for a chemical element.
what is a Subatomic particle
A particle smaller than an atom
What is the flame test
Detecting the presence of certain elements, primarily metal ions.
What is Bonding
A chemical bond between atoms, ions or molecules that develop attraction
What is the chemical symbol for Sulfure
S
What are Isotopes
Two or more forms of the same element that contain equal numbers of protons but different numbers of neutrons in their nuclei
What are the 3 main Subatomic Particles
Protons, Neutrons and Electrons
What is Transition Metals
Metallic metals occupying a central block
What 4 smell categories
Minty, Fruity, Putrid, Sweet
How is mass calculated
Mass number equals protons plus neutrons
What is conservation of mass
Total mass (grams) before the experiment, equals mass after in (grams)
What is the Nucleus
Center of the atom contains Protons and Neutrons
What is Valence electrons
What is Outer shell electron that associates with an atom
What is the formula for Ionic Compound
Mg3N2
What is Density
Ratio of an object mass to it's own volume
What is Matter
Has mass, volume (takes up space), particles
Who is John Dalton
proposed that all matter is composed of very small things which he called atoms.
What is electron configuration
distribution of electrons of an atom or molecule in atomic or molecular orbitals
Carboxyl, Hydroxyl, Methyl
How to break down density
Mass over volume, grams/Ml, Grams/Cm3
more than one hundred substances that cannot be chemically interconverted or broken down into simpler substances
How do you find the atomic structure
The number of protons in the nucleus of the atom is equal to the atomic number
What is core electron
Electrons in an atom not valance, do not participate in bonding
What is the Octet Rule
Rule of thumb that each atom has eight electrons in each Valence Shell
