It's Element-ary
The number of protons in an atom is also called this.
What are atoms?
An object's density is equal to it's mass divided by this.
What is it's volume?
Sweetened tea would be an example of this special kind of mixture.
What is a solution?
The tiny central part of the atom containing protons and neutrons.
What is the nucleus?
Form of matter made with only one type of atom.
What is an element?
The atoms of hydrogen and oxygen combine to form this.
What is a molecule?
A solid object will do this if its density is less than the liquid it is placed in.
What is float?
A pure substance made of two or more elements chemically combined.
What is a compound?
The sum of protons and neutrons in the nucleus.
What is the mass number?
An atom of the same element that has a different number of neutrons is called this.
What is an isotope?
The size of a salt crystal would be this kind of property.
That is physical?
An object with a volume of 5mL and a mass of 25g has this density.
What is 5g/mL?
Very low temperature is required to make materials into these.
What are superconductors?
What is neutral?
All atoms of oxygen have 8 protons, but O-18 has this many neutrons.
What is 10?
A group of two or more atoms bonded together by sharing electrons
What is a molecule?
The method of finding the volume of an irregular object by placing it in water and measuring the change.
What is displacement?
These determine how an element will change when it reacts with another element.
What are chemical properties?
This negatively charged particle orbits the nucleus.
Chlorine has 17 protons. A Cl-37 isotope has this many electrons?
What is 17?
A combination of two or more substances that are physically blended but not chemically bonded.
What is a mixture?
Comparing the density of one substance to another is called this.
What is relative density?
A property of matter that does not depend on the amount of matter and can be observed without changing the substance’s identity.
What is an intensive physical property?
An atom that has lost or gained electrons, giving it a charge, is called this.
What is an ion?
