What is Matter?
Matter is anything that takes up space (has mass and volume).
100
Pure substances include three things?
1. Elements 2. Compounds 3. Molecules
100
What is MIXTURES?
Contain 2 or more pure substances
100
What are two properties of Metalloids?
1. Separate the metals and non-metals on the periodic table. 2. Can have characteristics of metals and non metals
100
The number of protons equal the number of?
Electrons
200
What is in the nucleus of an atom?
Protons and Neutrons!
200
Mixtures include?
1. Solutions 2. Heterogeneous mixtures
200
What is Solutions (Homogeneous Mixture)?
Mixture with only 1 VISIBLE component (it’s not “chunky” - it looks like one thing, but you know it is 2 or more).
200
What is an element that is part of the Metalloids?
Silicon etc...
200
What is Periods are the ________ and the Groups or Families are the _________ in the periodic table.
Rows Columns
300
A stable Octet is when?
An atom has 8 Valence electrons. Therefore having a full orbital.
300
PURE SUBSTANCE
all particles that make up the substance are the same (have constant properties)
300
Mixture with 2 or more visible components (it’s “chunky”)
What is Heterogeneous Mixtures?
300
What are the 3 different families of metals?
1. Alkali Metals 2. Earth Metals 3. Transitional Metals
300
There are 2 groups in the Rare Earth Metals. What are they?
1. Lanthanide 2. Actinide
400
What are 3 properties of Alkali Metals?
Good conductor of heat and electricity Soft Metals Have one electron to give up freely so therefore they can bond with other elements easily.
400
What is Elements?
pure substances that cannot be broken down into simpler substances (contain only one kind of atom) - they are what are listed on the Periodic Table of ELEMENTS!
400
What is Compound?
Pure substances that contain 2 or more DIFFERENT elements stuck (bonded) together.
400
What is This Family does not want to bond with other elements because they have 8 valance electrons?
Noble Gases
400
What is an Isotope?
Atoms with the same number of protons but different number of neutrons.
500
Matter is classified into two main categories. Which are?
1. Pure Substances 2. Mixtures
500
What is a Molecule?
pure substances that contain 2 or more of the SAME element stuck (bonded) together.
500
Halogens are cool because?
At room temperature they can be a solid, liquid, or gas.
500
Halogens are the most ________ non-metals?
Reactive
