Periodic Table
The periodic table is organized by increasing...
atomic number
particles that are compact and uniform can be found in which state of matter
solids
Physical properties are any traits that can be observed by the
senses
Chemical changes result in
something new cannot go back
the term used to describe rows on the periodic table
periods
What are the 3 main groups on the periodic table?
nonmetals, metals, metalloids
This is state of matter has a definite shape and volume
solid
I placed a cup of room temperature water outside on cold day and came back 10 minutes later to see that it was frozen. What type of change is this?
Physical
Solubility is an example of
Physical Property
have characteristics of both metals and nonmetals
metalloids
Rn has similar properties to which other element on the periodic table?
He, Ne, Ar, Kr, Xe
This state of matter has particles which can slide past each other
liquid
Sandra bent a piece of copper wire this is an example of what type of change?
Physical
You know it is a chemical change when
you cannot go back or changed into a new substance
Electrons on the outermost shell are called?
valence electrons
Bromine has how many orbitals and electrons on the outermost ring?
4 rings 7 valence electrons
State(s) of matter that have definite volume is/are
solids, liquids
If I have one cup of tea and a whole kettle with tea what does that mean for their boiling point?
boil at the same temperature
Shelly mixed to unknown liquids and it created bubbles, odor, and changed color. These are indicators of what type of change?
Chemical
all matter is made of atoms smallest unit of an element
Atomic Theory
identify the type of element that would be a great conductor of heat and can be shiny in appearance
Metals
As temperature increases what happens to the state of matter
they start to move more and change state
If something has high conductivity meaning it is able to transfer electricity and heat easily would I want to place inside the chord or outside the chord
inside
T or F
The amount of an object ( example volume, mass ) affects its boiling point, melting point, freezing point etc
F always boil, melt, and freeze at the same temperature
ability to conduct electricity
