It Matters!
Everything is made up of this word.
What is matter?
Matter is made of over 100 of these, which cannot be broken down into simpler substances.
What are elements?
This table organizes elements in order of increasing atomic number.
What is the Periodic Table?
This is the name for an atom with an overall charge.
What is an ion?
We use this to represent compounds by using their element symbols.
What is a chemical formula?
Matter is anything that has these two properties.
What are volume and mass?
Elements are made up of these small particles.
What are atoms?
This is what we call rows on the Periodic Table.
What are periods?
This type of ion has a negative charge.
What is an anion?
Sr has 38 protons and two valence electrons. If it became a cation, it would have this many electrons.
What is 36?
The three states of matter common on Earth.
What are solid, liquid, and gas?
Atoms are made of these three subatomic particles.
What are protons, neutrons, and electrons?
This is what we call columns on the Periodic Table?
What are groups?
This type of ion has a positive charge.
What is a cation?
A fluorine atom has 9 protons and 9 neutrons. This is it's mass number.
What is 18?
This fourth state of matter is commonly found in stars, but can also be generated by lightning and neon lights.
What is plasma?
This is the name of the center of an atom, which contains protons and neutrons.
What is the nucleus?
These three descriptions are used to classify all elements on the periodic table - those of the same type share similar qualities of melting and boiling points as well as conductivity.
What are metal, nonmetal, and metalloid?
This subatomic particle is gained or lost from an atom to form ions.
What are electrons?
This hypothetical form of matter does not appear to interact with the electromagnetic field and is difficult to detect.
What is dark matter?
This subatomic particle is located outside of the nucleus.
What is the electron?
These two values are present for every element on the periodic table.
What are atomic number and average atomic mass?
These electrons are in the outer shell, and they are the ones used in chemical bond.
What are valence electrons?
