This is a better word for “stuff”
What is matter?
There are 2 elements on the periodic table whose valence shell only holds 2 electrons. One of these is a noble gas and the other one is this element.
What is hydrogen?
This state of matter has a definite volume but not a definite shape
What is a liquid?
This is the type of change that happens when condensation forms on a cold glass of water.
What is a physical change?
This is the most electron hungry element
What is the reactant?
This is what matters smallest parts are called
What are atoms or molecules?
This is another word for the shells of an atom where the electrons live.
True or false: All three states of matter vibrate
What is true?
This is the type of change that happens in souring milk.
What is a chemical reaction?
This is what the vertical columns in the periodic table are called
What is groups?
This is what the right side of a chemical equation is called.
What is the product?
A molecule is made of two or more of these bonded together
What are atoms?
Elements are happy (stable) when this is full
What is its Valence shell?
This is why the molecules in a gas don’t form a shape
What is because the attraction of the molecules is too weak?
This is the type of reaction that occurs when you ferment grapes into wine.
What is a chemical reaction?
What are Periods?
You can change this number when balancing a chemical equation
What is a coefficient?
These are the three states of matter found on Earth
What are solid, liquid, and gas?
What are Carbon, Nitrogen, Oxygen, and Hydrogen?
This is why a liquid takes on the shape of its vessel
What is because even though the molecules are attracted to each other, they are not as attracted as those in a solid?
This is what a chemical reaction is.
What is the process where one or more substances transform into one or more different substances with altered chemical properties, often involving the rearrangement of atoms and the breaking and forming of chemical bonds?
This is what the small number on the lower right of an element in a chemical equation is called.
What is a subscript?
This is the fourth state of matter that we don’t talk much about
What is plasma?
Matter is made up of tiny particles called atoms and molecules. The atoms or molecules that make up matter are always in motion. These two ideas are called the ____theory of matter
What is the Kinetic-molecular theory of matter?
This is the reason that a solid holds it’s shape
Why is because the molecules are very attracted to each other?
This is what a physical change in chemistry is
What is a transformation that alters the appearance but does not change the chemical composition of a substance?
This is what the bond of two nonmetal elements is called
What is covalent bond?
This is why you balance chemical equations?
Why is to make sure that there are the same number of atoms on both sides of the equation?
