True or False: In writing a chemical formula, the subscripts of the elements involved should be in their lowest possible ratios.
THIS TYPE OF MATTER TAKES BOTH THE SHAPE AND VOLUME OF ITS CONTAINER
GAS
This is the formula to calculate the number of Moles from Grams.
What is Moles = Grams/Gram Formula Mass
THE SMALLEST PARTICLE OF AN ELEMENT THAT RETAINS ITS IDENTITY
ATOM
This is the most active Metal on the Periodic Table.
What is Francium or Fr?
This is the name of the atomic model that was proposed by Thompson.
What is it has either lost or gained electrons?
What is a physical change?
Found in the nucleus.
What are protons and neutrons
CUTTING HAIR, FILING NAILS, AND CRACKING AN EGG ARE EXAMPLES OF THIS TYPE OF PHYSICAL CHANGE
IRREVERSIBLE
This is the most active nonmetal on the periodic table.
What is Fluorine or F?
This is why metals are good conductors of electricity and heat.
This is the formula for Density.
What is D = M/V or Density = Mass/Volume
This is the amount of energy necessary to remove an atom's most loosely held valence electron.
What is first ionization energy?
Where do you find the formula to calculate Percent Error?
What is Table T.
The energy released in the formation of a Bright Line Spectrum can be used to do this.
What is identify the element?
What is Solid?
True or False: argon is a diatomic element
This is the phase change where a solid goes directly to a gas, without every going through the liquid phase.
What is sublimation?
Metal atoms tend to __________ electrons forming __________ charged ions.
What is lose and positive?
