Matter and Density
Anything that has mass and takes up space.
What is matter?
The three main states of matter.
What are solid, liquid, and gas?
The temperature at which a liquid boils and changes into a gas.
What is boiling point?
The smallest unit of an element that retains its chemical identity
What is an atom?
The maximum number of electrons in the first electron shell.
What is 2?
The amount of matter in an object.
What is mass?
In this state of matter, particles vibrate around fixed positions.
What is a solid?
The temperature at which a solid becomes a liquid.
What is melting point?
An ion that has a positive electrical charge.
What is a cation?
The maximum number of electrons in the second electron shell.
What is 8?
The amount of space an object takes up.
What is volume?
In this state of matter, particles move freely and expand to fill the available space.
What is a gas?
The temperature at which a gas changes into a liquid.
What is condensation point?
An ion that has a negative electrical charge.
What is an anion?
The electrons found in the outermost occupied shell of an atom.
What are valence electrons?
The upward force a fluid exerts on an object.
What is buoyancy?
32°F or 0°C.
What is the freezing or melting point of water?
This property causes the surface of water to behave like a thin, stretched film.
What is surface tension?
The two types of particles found in the nucleus of an atom.
What are protons and neutrons?
An atom or group of atoms that has gained or lost electrons and now has an electrical charge.
What is an ion?
Two objects have the same volume, but one has more mass. This object will have greater _______
What is density?
Changes in this form of energy can cause matter to change from one state to another
What is thermal energy?
This gooey mixture of cornstarch and water acts like a liquid when poured, but turns into a solid when you squeeze or punch it.
What is Oobleck? (Acceptable alternative: What is a non-Newtonian fluid?)
A pure substance made of only one type of atom.
What is an element?
In this type of chemical bond, atoms share electrons instead of forming oppositely charged ions.
What is a covalent bond?
