Matter
Of the 4, this is the most energetic state of matter.
What is plasma?
These are the basic building blocks of all matter, living and non-living.
What are atoms?
The 2 main types of changes that matter can undergo.
What are physical and chemical?
This is the lightest element on the periodic table.
What is hydrogen?
The number of elements in the formula FeMgOHg
What is 4?
The state or phase of matter that has a definite shape and volume.
What is a solid?
These particles consist of 2 or more atoms which are chemically bonded together and can be either compounds or elements.
What are molecules?
During a physical change, this is never created.
What is a new substance?
This is the largest family group on the periodic table.
What is transition metals? (metals is acceptable)
This is the name for the elements and compounds found on the left side of the arrow in a chemical equation.
What is the reactants?
This is the term for how much space matter occupies.
What is volume?
These are the 2 subatomic particles found in the nucleus of an atom.
What are protons and neutrons?
This is one evidence that a chemical change in matter has occurred.
What is a temperature change, light created, a new substance is formed, a gas is created, A sudden color change? (any one of these will do)
What are electron shells or energy levels?
This is the name for the elements and compounds found on the right side of the arrow in a chemical equation.
What is the products?
This term tells us how much matter an object has in it and affects its weight.
What is mass?
These negative particles are loosely bound in energy levels around the nucleus of an atom.
What are electrons?
The common name of the chemical change where oxygen reacts with iron to form iron oxide.
What is rust?
The noble gas family of elements don't react with other elements because these parts of their atoms are full.
What are their valence shells (outermost electron shells etc)
When balancing a chemical equation, these are the numbers that you can change.
What are coefficents?
When a vapor or gas cools and becomes a liquid, we say this process has happened.
What is condensation?
The outermost electrons which are farthest from the nucleus and can be shared with other atoms during bonding.
What are valence electrons?
Unlike many physical changes, you can not do this to a chemical change very easily.
What is reverse them? (undo, change them back etc.)
Silicon has properties of both metals and nonmetals and is therefore a part of this oddball family of elements.
What is metalloids?
The total number of atoms in the products side of this is equation: BF3 + Li2SO3 = B2(SO3)3 + LiF
What is 16?
