Matter
What is matter? Provide the two necessary qualities.
Matter 1.has mass and 2.takes up space.
What is the periodic table and who came up with it?
The periodic table was created by Dmitri Mendeleyev and it is a table where the elements are arranged by properties.
What are the properties of Metals?
Metals are shiny, can be bent/stretched, and can conduct electricity.
What is a molecule?
A molecule is group of two or more atoms that are chemically joined.
What is an atom?
An atom is the smallest particle of an element that still has the properties of that element.
Complete the following sentence: The three states of matter are _________.
The three states of matter are solid, liquid and gas.
How are elements arranged?
Elements are arranged by their atomic number.
Non-Metals
Complete the analogy.
If atoms are like letters, then Molecules are like ______.
If atoms are like letters, then Molecules are like words.
What overall charge do atoms usually have? Why?
Atoms have the same number of protons and electrons. Since protons have a positive charge and electrons have a negative charge, they balance the atom out and give it an overall neutral charge.
Complete the chain:
Matter --> _______ ---> _________
Matter --> Elements --> Atoms
What kind of information does the atomic number provide about the element?
The atomic number states the number of protons found in an elements nucleus.
What are the three groups elements can be classified based on their properties?
Metals, Semimetals, and Nonmetals.
A water molecule is made up of: two Hydrogen atoms and one oxygen atom.
Draw an atom. Label all it's particles and indicate their charge.
Drawing should have a nucleus made up of protons (+) and neutrons (0), and electrons (-) floating outside the nucleus.
Substances that cannot be broken down any further are ____________.
Substances that cannot be broken down any further are elements.
Where does the name periodic table come from?
Fill in the blank: ___________ are elements that hardly ever combine with other elements to make compounds.
Noble gasses are elements that hardly ever combine with other elements to make compounds.
Why is the element carbon so important?
Carbon makes millions of compounds (carbon compounds) and are the main parts of all living things.
Where is most of an atom's mass found? Name the particles that contribute most to the mass.
Most of the atoms mass is on the nucleus, so protons and neutrons make up most of an atom's mass.
Why is it possible that so many kinds of matter exist?
So many different kinds of matter exist because atoms can join together in different ways.
The atomic number of Magnesium is 12. What does this reveal about protons and electrons found in Magnesium.
Atomic numbers tell the number of protons found in an element. Elements have the same number of protons and electrons. So, Magnesium has 12 protons and 12 electrons.
Elements in the same group share the same properties.
What are compounds? Give an example of a common compound?
Compounds are made up of two or more elements that are chemically combined. Water, Salt, and paper are some common compounds.
Silver has 47 protons. If you remove a proton, what charge will it have?
